Wow, very impressive. Now I want to do something like that!

Oddly enough, I just finished this build a little less then an hour ago over at Skudmunky's house. (He's the only person I know with a soldering iron).
My very first audio DIY and it works, what shocks me to no end.
There is only one problem with it, I don't have a bloody male-to-male 1/8th inch connector cable anywere in my entire apartment!
So I'd better get out to you-do-it and get some parts soon.
Yeah, turned out quite well. His entire build is a heck of a lot cleaner than my first. I had a ton of wire mess, chopped up the tin with scissors since I didn't have a dremel, and I still loved it.

You know, I honeslty I have no idea what those caps are. I was expecting to get a set more like these but ended up with the pair you see in the pictures. Its the same model number and specs from mouser electronics, just twice the size.
But the amp works, so no complaints.
Just finished burning in my Ultimate M3 preamp. I sourced the case from DIY fidelity. I used a DACT CT3 source selector for handling my inputs. I used a 50k stepped attenuator from DIY fidelity which I assembled. I installed two switched headphone jacks which terminate to two preamp RCA outputs. I used a fully populated STEPS power supply set at 30V. My M3 is populated with vishay dale metal films, Nichicon Muse caps, etc. The gain is set at 7.5 but I installed Sip pins for gain adjustment. OPAMPS are BURR Brown 637au and 627bp for the ground channel. All wiring is 24 gauge silver tinned copper wire.
This is one sweet sounding headamp/preamp. I connected it to my HYPEX power power amp and was rewarded with the M3 sound that I am familiar with, tubey, quick and impactful. I never knew that a stepped attenuator could have such an impact on the sound. Much more transparent than the alps blue velvet.
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)
I started and finished a PINT today. My first SMD work, aside from the 627's I mounted on Browndogs before I started the PINT. Turned out pretty nice, and sounds fantastic. The Duracells will be replaced with 170mah's when they arrive.
