My case mod:   It's simple - I just dremelled a hole in the top of the case and attached some mesh I found around the house.   Lets me see the tube and lets all the heat easily escape.           I <3 my Mav 

Quote: Mine's the one on the left (with the blue cap) in that picture.   There's also an identical one on the other side of that jack (not visible in the picture).   Is the serial number the number on the sticker? I'm assuming, since that's the only number I can find...

Just pulled off some major resistor-replacing! Swapped R70 and R71 with 300ohm resistors. Swapped R54 and R55 with 5.7Kohm resistors. All swaps with DIP socket brackets! Completely removed hum/noise from headphone out with my 64 ohm HD280 Pros! Holy ****! It sounds soooooo good...

Haven't had time to try the soldering yet, but when I do I'll let you know how it goes.

From spanky's FAQ thread: 8 PIN SOLDER TAIL DIP SOCKET - 08-3518-10 Got mine today, along with a bunch of resistors and a couple heatsinks

lol..... The MK III? Or a new mystery product?

It's about as noob-friendly as upgrades get. Order the parts, open up the D1, pull the old op-amps out and put the new ones in. No soldering or anything. LT1364 goes in the socket next to the tube, LM4562 goes in the other one.

Just swapped op-amps to the recommended LT1364CN8#PBF - LM4562NA/NOPB combo. Huge difference! Sounds soooooo goood. Cut down a lot of the headphone hiss, too.

bear, I'm assuming those op-amp impressions were for the headphone amp. Have you tried any different op-amps for the DAC? Which do you think would yield the best sound quality? Also, does anyone have a better place than ebay to buy some 5670 Raytheon Windmill Getters? PS. Mine...
