Stop the Insanity

We have been playing with the high voltage supplies on the "direct drive" quads and on a whim we tried some higher valued caps that the "stock" 0.001µf values.

I just happened to have a bunch of these 4µf caps and we gave that a go and things improved.  Onward and upward we went in values to see if there was a limit we could exceed.

10µ was better than 4µ and I think it may have had something to do with the Italian made capacitors which are obviously audiophile approved which can be seen by a closer inspection of the brand.

25µ was next and again for some reason things got better so next up are these banks of 50µ @ 900V caps.

Stay Tuned (or come listen to them in early November at the Capital Audiofest.)
