USAFA: Audigy 4 (roommate's computer) ---> DIY GB-150D-based integrated amp (stereo configuration, remote-controlled, power-on delay for output, and heavily class-A biased (3.9mA/channel) LM4562NAs used in preamp section) ---> Yamaha NS-527 (modified with Vifa 6 1/2" woofers, Panasonic film caps in crossover, and heftier internal wiring)
Ghey-C'97 (my piece-o-crap issued laptop) ---> PPAv2 (class-A biased AD8620 (2.5mA/channel), 8600uF pre-regulator, LM338 high-current regulator, 40mA/channel output bias) ---> Grado SR-225 (yes, I bring my headphones home from the Academy during leave)
Very nice case and engraving including the font, the remote is a nice added touch, thats why we have long headphone cords so we can sit back a ways from the amp, at least you can control your amp remotely now.

Outstanding work, rille. Did you program/design the logic board yourself?
Do you mean this board?
It's a kit, Remote1 from Dantimax. I only added some parts for the indication of the selected input. I'musing the mute relais for this. Dantimax has also other kits, e.g. relais attenuator or input bords for 3 or 5 inputs.
Here's my switch box with 5 inputs and three outputs. I'm waiting on knobs and I'm going to install DC blocking caps and eliminate the ones in the amps.
This is my first real DIY build (from scratch that is)

This is my 3rd attempt in building headphone amplifiers, the first solid state design for me and my most recent (finished) build...
As has been said before the M3 is an awesome amp that easily shows the quality of source and recording. It is extremely neutral and very transparent and, after many hours of burning in, has almost entirely lost a certain edginess that I noticed in the beginning.
Thumbs up to Amb (and Morsel) who designed the amp...!
