I can pick out certain notes or noises and always remember them, maybe i'm good at this with having been an audio engineer

I suppose one could train ones hearing for remembering small details. But can you remember these changes over a period of time, say one week?

for bass, Herbie Hancock did an album and the double bass solo on it was incredable, perfect for testing lows.

I think it was a record (vynal), still trying to find it.
still looking.

Many times good sounding vinyl albums get 'remastered' for digital. Probably because of the larger headroom on digital. I rarely found a remastering job worth the effort. Please try before buy

Yes very easily, 2 weeks would be pushing it though.

I have always worked with audio so I suppose I have got good at it.

I built a new, serious version of the passive filter part, with 1% PS caps, precision resistors and matched inductors. I've just spent an hour listening to it. Wow. Guys, you really should try this.
The clarity, resolution, it's great. It beats the hell out of my opamp setup.

Thanks guys,

The filter part is very easy. Building the FET-stage using the HDAM lay-out is a bit tricky.
But it fits without cutting any traces .
I use some MKC output caps that I had, but I think i'm going to put in some Auricaps, or Reliable.

Maybe i'm even going to put those nice shiny metal cans back....

Ray.

Maybe it's worth the effort making one dedicated PCB, for both the FET-stage and the passive filter? I have the old acid tank standby...
