SRH940 velour pads are larger and thicker than the stock M50 ones. I'd recommend them over the DT250 pads. But although the replacement pads give increased comfort and room, they are probably still not going to completely prevent your ears from touching the driver lining.   The SRH940 pads...

T5, Thunderpants, Paradox.

I use a linear regulated USB isolator for this. The amount of benefit really depends on just how good or bad your existing USB port and computer PSU are.

The velour vs leather ear pads difference was probably also a factor.

The ground loop problem I had before is gone now. My Teralink-X2-M lives again!   I mounted a USB isolator on top, and wired the USB cables directly to the board. Here the isolator draws clean power from the Teralink's built in PSU. But normally this isolator has its own linear regulator...

"Create an Equalizer for All Audio in Mac OS X" http://osxdaily.com/2012/05/18/equalizer-for-all-audio-mac-os-x/   This uses Soundflower and AU Lab. Both of which are free to download. Have not tried it myself yet.

Agreed. And the initial checks on the Mini³ website are a good place to start.   Try reflowing R5L, R1L, and L1L if you have not done so already.

The last two items you listed are by fred_fred_2004. He's an established Head-fi member and regularly contributes in the DIY forum here. If you're looking to buy a CMoy, you won't go wrong with him.   I'm not familiar with the other two sellers. (Doesn't mean they're not good, I just don't...

Not really related, but with tube amps it's best to leave the headphones unplugged for 30 seconds or so while the amp warms up.

Quote:   They're also used to filter the noise generated by the device itself so it doesn't interfere with other devices.

It's true that the problem is from some Javascript code on Head-Fi. But tracking down exactly which parts of the code are responsible is not always a simple thing. Since different browsers and even different versions of the same browser can react in subtly different ways to the same code, it...

It depends on the specific laptop and DAC/amp. But yes, a USB DAC/amp will almost definitely improve sound quality compared with a laptop's default headphone output. 5V isn't a lot, but it is enough to drive most 32Ω headphones.   The DACport you mentioned earlier is well regarded, though I...

Quote:   While that is the goal of all amps, some achieve it better than others. Everything that you can plug headphones into has an amp. The source's built in amp may have enough voltage to get loud, but it may also get slightly noisy at the same time. Or it may fail to supply enough...

Looks like the TRS jack's pcb pins are just wired that way.  

Works well for me. And the gallery bug is gone. Thanks for the quick fix!
