After 11(!) years i have finally finished my amp...... Finally having a home studio i decided to give this build a final try, only to find that i had connected the powertransformer incorrectly....oh well....
I coupled the amps with the Darwin source selector and and Joshuatree volume control.

The amp pushes some diy speakers and i really like the sound: detailed and it pushes some low end.

Thanks Mauro ande the guys at Twisted Pear!

I want to bump this up. Recently I changed speakers. From 25 year old Thiel CS-3.5 to new Klipsch Heresy iii. The impedance is close, around 5+ohms for both as a minimum impedance. The efficiency difference is large, 87 dB for the CS-3.5 and 99 dB for the Heresy iii.
I wondered how my Evo single with the last mod would sound at several milli watt output. The linearity and tone are way better than expected. The graphs and measurements done by George are vindicated. These amps are spooky quiet and deliver dynamics at sub watt output. Used with Lowther’s many years ago. But the coloration from the drivers masked how well the amps worked. Plus maybe the 15 ohm impedance was a little issue.
With a more normal load and very low distortion speaker the amplifier is so transparent. The sound is easily the best I have heard.
