Feedback (The good kind ) !

“Pat,
Thanks for the great work on the Fisher 400cx2.  It has brought new definition to the Zu Definitions IV.  Following the power supply rebuild, ground scheme improvements, recapping with Super Caps, and flawless build of the Gold Point attenuator/power switch this is one of the finest vintage preamps I have ever heard.  I try to shy away from the audiophile adjectives because I have a hard time finding much meaning in them, but this baby is musical with explicit definition.  Midrange expression is phenomenal and nothing is lost at the extremes.  I would put it up against just about anything (within reason of course) and am confident it could hold its own, particularly the phono stage.  Great job, money well spent.

I really enjoy improving the performance of the classics
