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...

For CD ripping: EAC guide Mine was on hold in China for several days before it moved.

I have my HD280s hooked up to the tube out this way. ^ Sounds great with only a couple volume notches.

On a whim today, I decided to test my D1 headphone amp with some Sony MDR-V150s I had laying around. Weirdly, even though they're even lower impedance than my HD280s, the hum was just barely audible, and the gain was acceptable on the first few notches. Why is this, because they have a lower...

Would there be some way to easily replace a few wires that run to the headphone amp with shielded ones? I'm anxious to hear what the engineer has to say about it. I'd still want to upgrade my phones, though. Anyone have any suggestions that would pair well with the super-high-gain...

So you've tried your k601s (120 ohm?) out of the headphone amp and don't get any hum?

Thanks for the quick reply. I guess I should have mentioned those two things in my first post. The first time I tried the headphone amp it was fine, except for the hum. The solid state out on the back still works just fine. Sounds like a loose cable issue, then. I'll double check to make...

I've encountered some puzzling behavior in the headphone amp of my maverick. Firstly, I tried disconnecting everything and plugging it in to a separate power outlet, the hum is still there. The hum is the worst when the volume dial is all the way down, as I turn the volume up the hum...

It appears that the S suffix just means it's a straight cable instead of a coiled one.
