Music Maker of the Month - in Munich!


It is fitting that I have let Music Maker of the Month slide for so long. With the work Dietmar has done in building his system, he deserves a Music Maker of the Year award....

Dietmar has built nearly every component in his system. It is very evenly balanced with no excesses in any one area.. ok.. well, that sentence is probably best written as even excesses in all areas... but what I mean is that his front end is not in a different class than his amplifiers or speakers... every area has received careful, well planned attention... he built his amplifiers... his horns... modified his drivers.. treated the room... worked up the crossovers..

and the sound? he nailed it... natural is the only word you can use... and that is the perfect word... from the first words out of Elvis's mouth, you knew he had it... absolutely stunning...

(so, how about we proceed to a bunch of bad cell phone pictures? classic hifi heroin from my side... I spend my money on junk, not camera equipment... more horns! more tubes! more drivers!)


Basshorns were built into the wall.. this is his attic... see the slope on the top right? the horns are actually on hinges to act as doors... so this one is open so JC and I could climb back there and look around...

which reminds me.. in the first picture, you can see how he has filled the peak of the attic with sound absorbers of differing density and then covered it to look like a flat ceiling.. genius!


JC for scale... note behind the mid horn you can see the floor to ceiling and wall to wall basshorns... which use the room as natural extension... eat your heart out PW Klipsch!


Have you tried a few drivers, Dietmar?


here is the control center... EMT... (check out the cabinet he built for it!).. phono and line stage.. digital crossover and delay... all right in front of the listening position.. why get up when you do not have to?


horn front shot... on rollers for easy movement left and right... why? you ask..


because of the well known dispersion characteristics of snail horns... check out those graphs....


amplifiers in use...


yeah, he made this himself.. of course he did...


ever built a transmitting tube amp with mercury rectifiers? yep... done that as well...


more Dietmar and more scale....


and you know a humble, soft spoken guy like Dietnar measures.. it is the proper engineering way.. you have to listen *and* measure.. you just have to.... one of the rules... yeah.. and how many of you have a flux probe? (yes, dave, I know you have Sid Smith's old flux probe.. I was not including you)...

Astounding work, Dietmar...

more Munich High End Impressions....


This post gets to the heart of why we go to shows. Yes, we want to walk around and sample the gear as we are always looking for new and different, but we mainly go to see friends... and make new ones... However, when Silbatone shares something from the archives, you listen.. listen for what it does right... of course you will note what it may not be doing perfectly, but man, oh, man does the Western Electric 16 horn do something right....


it is not like you need to see any more pictures of this horn from me.. I have admired its form for years and years. I think it belongs in the Museum of Modern Art. Dave and I are never ones to copy, but when a commission came in for me to make this one - with the option to make improvements where I deemed necessary as long as I kept the theme in place - my mind started swirling... that form in my life on a daily basis?... and now having heard the directness... and the absolute best "scale" I have ever heard.... well, sitting in front of the 16 while in Munich has pulled my vote over to "Amen. Let's do it!"...


Yeah, as always with such high resolution we struggled a bit. The bass was not really integrated perfectly, and the new 300b was too forward for this setup. But by day three with the WE242 amp now in play and Frank having done his Frank thing with the Van Den Hul cartridge, it was doing something so very right in the middle. I guess four field coil compression drivers running full range will do that! roughly 80 to 6k at what, 120dB? that is crazy talk... and directly connected to the amp... no crossover parts??? whew! So, considering that I tell people a year to get a good horn tuned, three days for phenomenal mids is not bad at all!


I did lament the fact that we had to close the room at night. That is my pet peeve with HiFi shows. With all of this gear here, we should be hanging out and listening late into the night. That is what Dave and I like to do. But we had to settle for too much Bavarian brew and giant round tables filled with thirty of your closest friends from a dozen different countries. I guess that is a good second choice. Oh, even the vegetarian ate well. No sausage, but plenty of super good food - that giant white asparagus, cheeses, pastas, potatoes, salads with real greens, and of course a barrel of pretzels to go with my beer!


so who made up the rambling wreck this year? man.. Silbatone...Bae, Joe, JC, Lee, Manho.. too many Euro Joes - Wolfgang, Christian, Manfred, Rogell, Holger, Sikking, Mayer, Von Langa.... Japan and GIP in the form of Suzuki, Kikawa, and Kawanishi... the analog guys, Schroder adn Schick.. the dutch kids, of course... a few Americans - Stewart and me.. even a real deal local diy superman - Dietmar... and I am sure there were others.. what a mess it was trying to get this group to move about.. like three year old soccer teams.. a slow moving blob.... so the table shot is of about half the "team".... were took up a few tables...


oh.. a funny one to me.. after the show one night... sitting in a really wonderful outdoor beerhall, I mentioned that I had not eaten in twelve hours and was also quite dehydrated... so traditional German rehydration was ordered up special just for me - 72 ounces of half lemonade and half weiss beer! by the time I was halfway through, I had to stop for fear of embarrassing my 150 pound, now drunken self in a foreign country! and of course the waitress, who was barely taller standing than I was sitting down, could have carried me out under one arm... she was bringing those giant steins ten at a time... I was genuinely scared..


I also was able to get a bunch of JC and Stewart time in... joe and I hung out non-stop in Holland, but the two of us together do not push each other much.. we are just observers of culture on a stroll... a fabulous time, but WAY different than JC and Stewart time... those dudes were great... talk of tube construction.. regulation.. self noise.. stuff to try... early Eimac audio experiments.. and then quickly somehow we are back to the city.. Ornette, Kirk, and Ulmer.. then Mingus... and Hartman and Coltrane.. wrecking me with my own favorite things: Eimacs, direct coupled circuits, Trane, Mingus, and what happened to jazz... late into the night and into the morning.. hanging out with those guys was inspiring... stewart, I am waiting for teh day when I can come visit that brain bank of yours and that vinyl... and JC, brother, I just want to stroll Sweden, preferably in summer, and talk life and circuits, after all, they are the same thing....


and back to "the sound"... well, I can honestly say that I have never heard piano and violin like I heard in that room... so direct, so honest... MJ always says, "metal horn"... repeats it like a mantra.. and based on my experience with the 24 and 16, I get what he is saying.. preservation of energy may be the single most important tenet of HiFi... it somehow preserves more of the emotion when you have this drama of scale... the best example of this is when a very well known cartridge maker came in.. he was weeping in a room of fifty other people.. most total strangers.. he was just moved.. and I know exactly where he was... it was heavy... overwhelming, really...

Remote Intact Autoformers...

.

I forgot to show you guys what I shipped right before I wandered over to Holland and Bavaria...


The knob drives the display and the volume (duh)... in addition to volume, the remote controls balance, mute, and display on and off.... with the logic, -56dB to +7dB is available in 1dB steps...


The bright sun exaggerates the display glass... I really like the soft glow in a dark listening room... not too much light...

the traveling demo unit should be back any day now... so speak up if you want on the list...

Peace,
Me

Munich High End - show impressions...

.
ok.. I have to be honest. This is rather awkward for me. I am not a reviewer. I am a manufacturer. However, I am always asked for show reports. It would be very easy to read this as my attempt at shooting down my competition. But, as you guys probably know, that is not really my style. I am always looking for potential. That is my gig. The eternal quest for something that communicates music. Besides, my demand is far exceeding my ability to supply as it stands today. The last thing I need now is to pick up all of their orders...

so, with all of that having been said, take it however you want.. this is my best pick from a an hour or two of wandering each day.. I am 99% sure I heard all the horns that were there.. if it is not mentioned below, there was something, or a lot of things, that really got to me.. as always, your ears may vary...

+++++++++++++++

first, the best all around sound at the show... and super nice guys.. was Musique-Concrete....



this blurry picture is perfect... you can't tell which handsome scruffy guy is which... (big laugh).... anyway, their sound was good.. good all around.. maybe the highs could have been a touch sweeter, less electronic, but it was good... not as dynamic as the big WE system, but balanced, integrated, easy to listen to.. made music.. good work, Marco!

(that picture kinda freaks lisa out.. paint the speaker black and it is also eerily similar to what is in our den... and Marco and I just met when this picture was taken!)

+++++++++++++++++++++


Auto Tech had some Le Cleac'h horns there.. fiberglass... but well built.. the seam has been minimized.. but the rear has that black damping spray that Lisa won't allow in the house.. however, for a DIY'er on a budget, they were noticeably less plastic sounding than Avant Garde...


++++++++++++++++++++++

on a general horn note, many systems, as always, were very restrained.. not sure why.. what is the trend of making horns sound polite? sad for a dynamics and scale guy like me.. I like *life* in my music.. if you can read the paper while listening to Sonny Stitt, you goofed...

and then there was *dry*.. horns that had no flesh.. I guess a little bit of Beryllium can be nice, but a whole stack of it is way too much....

as you can see, not much to write home about in regards to sonic marvels.. I guess even a well done show in Munchen is still just a hifi show.. the good news is that there was lots of vinyl...lots of turntables... woo hoo!!

my next post will have more good stuff... fun people and a lot of thoughts on Silbatone and the WE16...


Oh, one really cool item that I forgot to mention:



this sweet little 7", in combination with an Iphone (or others) app named platter speed is just what I need for my 50Hz strobed Garrard 301... yippee! oh, platterspeed is a free app... so if you already have a test record that you know is accurate....




ok.. back to work...

The (almost) original Strain Gauge


First I want to offer my most sincere apologies to Barbara and Julius because if Frank ever sees this installation it will surely kill him.


I finally scored another piece of history and had to do the typical get it done installation to see how it works.  I grabbed a piece of 1/4" plywood and hacked out an armboard which is held in place by amorphous and 80% nickel cores :-).   


Unfortunately the PS was kaput so that bummed me out a bit... sure i could spelunker into it but I know it is a crappy compromised solid state design that really isn't worth the effort particularly when a fine supply such as this is resting on the shelf below.


Before all of you gasp at the fact that I actually built something without wheels, I'll point you to the german version of the PS that Frank (hope you are still with us mate) took to the ETF in 2008. (pic borrowed from holger)







If the german one is still to crude (I think it is beautiful) I guess I could get off my arse and assemble the last two of the 'drug through the hudson ones.


Now that I think of it... I'll just keep listening to the rats nest and take the boys Kayaking... Summer has officially hit NY.

Because Dave is too humble...

.
to even tell me this review is out there!!

it just landed in my inbox... Enjoy the Music... a glowing review of his autoformer volume controls...


Olsher's quote:
"The sonic benefits of the Slagle AVC accrue from the elimination of an unnecessary electronic gain stage and replacement of resistive attenuation from the signal path. Bottom line: a superb volume control and the best $350 investment in audio! "

yeah... that is how I feel about them....

Those Dutch Kids, Again.....

.

WOW... yeah... I said it.. wow... Joe and I knew when we met Caspar, Remko, and Wilco at CES that they had the passion... so when they invited us up and said they would have a party, we had to make that happen... fly into Schipol... train to Utrecht and then Geldermalsen... and only an hour from Schipol is Audio-Life... and their shop is wonderful! ... I just found this six moons road tour page...



it is in an old factory... five stories... there is some retail being done, but it is always in the background... just hanging out listening to music is in the foreground.. the rooms are chill... the lighting is just right... and for the party, well, it was phenomenal... family style barbecue... a pretty out there jazz band... and DJ'ing from an Ongaku and a laptop...


it appears that someone has covered the audiophile portion of the party... so click HERE if you want the youtube party video from a local rag... when we landed they were doing the serious audiophile thing with Musical Affairs and PEL... you can see from the video... that stuff is pretty good for cello and low volume vocals... nice and rich... clearly constructed by people who care.. better than nearly everything at Munich High End... but it just cannot handle complex... so, for the office, perhaps perfect... it just cannot be your only system... Bruckner eats it for breakfast...


but what that perspective misses is all of the kids underfoot.. they know all the best hiding spots... they showed me the super loft... oh, and there was Bob Marley on the projector.. and lots of friends until the first rays of the sun... super, duper thanks, guys... you will see and hear more about them over the years... we just hooked them up with Suzuki, so now they are a destination... if you want to hear GIP outside Japan, you need to go to the Netherlands.. trust me, you will have fun...

Another Giveaway.... 2 UTC ouncers for free.


Put your name in the comment field to enter.  Read below for the story and specs.

I was down in DC a few weeks back for a family celebration and I was able to sneak in some time with my audio family.  I saw Barry on the way down and then had a great time with family at my nieces graduation.  When the festivities ended about midnight I rang Ijaz and as usual he was ready for the third shift.  Mike was interested in coming by to chat about crazy ideas and when he showed up he came with booty in hand that he had pulled from equipment over the years.

It was an assortment of UTC "ouncers" he wanted to see put into use and I felt obligated to accept them.  In the lot there were 4 of them marked 25A27 and my internet searches didn't turn up anything so to the bench I went.

I suspected they were lineout transformers but the interesting thing is when put in reverse they seem to function comparably to the mic inputs as SUT's.  The nice thing about them is the step up ratio is much lower than the traditional "vintage" mic input units re-purposed for SUT usage which means you do not automatically load your cartridge down.  They appear to be 1:9 devices with a CT that will allow for a 1:18 ratio.

 The above measurements are using a 15 and 40 ohm source impedance (denon 103 and 103R) and the termination is 47K.  Ratios are roughly 1:10 and 1:20 with some losses and the 20Khz top end is met.  On the low end bandwidth will be low enough to pass the footsteps of your neighbors.

For comparison, I'll offer up some earlier plots from some peerless 4722's and 4665's.  Of course these are not apples to apples comparisons but if you can deduce that this particular apple is your flavor....

Put your name below and claim them.

They may be brilliant, they may be a headache, they may even hum yet the rule remains the same.  If you win it, you need to try them and report back.

Addendum...  As with all of the giveaways here, things are random and you need to enter your name.  We don't do first come first served and let lady luck determine who gets them.   They came to me for free and they will all go out to people for free.  I just need to measure and document them so it may take some time.

Precious Metals

 



My newest investment strategy is moving away form cash under my mattress to silver on my shelf.  Given the worth of the US dollar, I hope it is the correct move.  Pictured above is about 8 pounds of high purity silver magnet wire in assorted sizes.  These sizes will allow me to do a small number of autoformers and some nice low ratio SUT's for a handful of customers that have been pestering me for years for silver.


 First up are 6 pair of the chapman/bent modules to go to Korea with some Step-Ups to follow.  Next a few samples go out to some OEM's and family members to try.  If all goes well I may try to do what the Hunt bros. couldn't accomplish in the 80's.


As a final note,  in the next day or so we should crack the 100,000 pageview threshold and JJ and I want to thank you all for putting up with out antics and coming back for more!  I'm sure the content is about to increase a bit in the next weeks with Munich on the horizon.

so let me hear about your DHT headphone amp!

.
I love this blog and was flattered Jeffrey asked me to write something. Few days ago I finished this 56 dc 171a headphone amp (more than 50% dht – 80 rectifier) – nothing fancy, scrap chassis, low cost.


Both my son and I thought it was OK at first - a bit flat. Today Jeffrey suggested to remove the 9ohm load resistors I had on the 5K:8 OPT's for the 32ohm headphones. I let my son have the first listen and in two notes he pronounces "It's Better!". It really came alive – open and fluid. Ten minutes later, thinking of Jeffrey, I treated my son to his first experience with Jimi...

I am working on my Juju..

I am working on my Juju.... or perhaps more properly titled "Robert Johnson's Deal with the Devil"...

It all started innocently enough.. a simple link to this new set


but it began to come on like the locusts... twenty emails in three days... all about Robert Johnson... maybe I should say it came on like the floods... yep... definitely.. it came on like the floods...


Everything in this picture from the first row of trees up should be land. Seriously. We drove the bridge today. The water goes for miles and miles and miles into Arkansas.

I *know* why. I am not sure anyone else has noticed this, but this is clearly a direct result of Robert Johnson and his deal with the devil. Do not accuse me of being gullible. I know what I am talking about. I used to ride my bicycle up and down Highway 61 on a daily basis.. and not just anywhere... right smack dab in between the two intersections that are believed to be the crossroads where the man sold his soul to the devil. Do you know what year the Mississippi River set the record? 1937. Do you know what year Robert Johnson recorded the vast majority of his records? yep. 1937. He only recorded for less than a year - he was dead by summer '38. Do you think it is a coincidence that we are going to inch right up to that record, maybe breaking it, maybe not, in the very week of his 100th birthday? Not me... that is the devil at work... the ongoing deal of his pact...



Today is the 100th birthday of Robert Johnson.. I am scared... ... you know I am working on my Juju... and my Juju comes tonight... Jon Spencer Blues Explosion at the Hi Tone... if that ain't Juju, nothing is... I will be with the devil and I will be spared...

Jon Spencer Blues Explosion at YouTube

and another thing... I will not be around in May of 2037!

Peace,
Me







p.s.... a few more pictures and thoughts... we were extremely lucky... we live in the 100 year flood plain... after the storms last weekend, my shop flooded.. just an inch or two... and my yard was saturated and had that same inch or two... but the house was spared.. it was flash flooding.. however, had it been only a few days later it would have coincided with the Mississippi peaking and it would have certainly been a foot or two into my house and many, many, many more homes... my house is just out of view of this shot to the top right... there should be NO water in this picture.. this is a high school and a hospital complex...


to give you an idea of high high it was locally, this is JP on a bridge in the neighborhood park.. yes, bridge.. so the water was supposed to be below this... clearly it was not...


and lastly.. this shot taken yesterday... God's apology for passing on Robert Johnson's record deal...

Offshore scams or mistaken email??

This showed up in my inbox today and I thought it funny that the scammers had Simpson humor.

WooHoo... a full sawbuck!  How can I collect?


Funny thing is, I suspect the above $20 deposit is legit and some other Dave Slagle in St. Augustine FL has far better friends at the bank than I do.

I just wish his Honda Dealer would stop sending me notices that it is time for service on his accord.
