Peter cheated this time;

Ugly!

Peter, those amps are looking incredibly good, indeed
I had hoped for your oppinion on the nonpolar BG's versus film caps, hope you find time to get around to do a test.

Thanks guys, especially to Mr. Pass for inspiration.

Steenoe,

I see no way to install 100uF film caps in place of BGs.

I did comparisons of films vs BG N in DAC coupling and I could only find one type of cap that was better in that particular application: it was teflon V-Cap, everything else (Jensen copper, MIT RTX, Hovland, Siemens MKV, Russian PIO, Woner Cap, Infini Cap) didn't perform how I like it. However, I was not looking for a sound that was impressive, but one that is true and convincing.

Peter,

How hot does the binding post and input RCA get? I noticed you didn't decouple the angle alluminum from the copper plate.

Did you source the copper plate from Metal Supermarket?


thanks,
m.

Yes, the copper plate is from Metal Supermarkets.

I was also concerned with temp of aluminum angle, but because of small gauge it does not transfer heat well, so RCA and binding posts are only slightly warm.
