Just wanted to say thanks for this, I used it to do the mod last night (did everything except the front side of the drivers with all the holes). Took me about 40 minutes total. A tip for everyone else, stick the dynamat in the freezer for a while before working with it and its a lot easier to...

I was speaking about clipping on the DAC section, which madwolf found is due to a possible design defect. Wasn't talking about the difference between the battery and usb power (though I definitely hear a difference between the two, even with my low impedance denon d2000's). Quote...

I did the fix and I no longer hear clipping, haven't had too much time to evaluate but I like what I hear. This was my first experience soldering SMD's, it was pretty easy - at least after watching a couple how-to videos on youtube. I did spend a good bit of time practicing on some old computer...

I found a good test to demonstrate the clipping on the ibasso d4 DAC section - play Radiohead, In Rainbows, 15 Step, right about 2:30 - 2:36, there's a quick kick drum section. When i have the itunes volume turned up to 100%, there's definite clipping/artifacts. If I turn it down to ~70%, and...

Does anyone have a few extra 2.2k resistors? I'll pay for the stamp, just don't want to buy 200 of them for $10. (TIA) I thought I noticed a bit of clipping on a few songs, and turned down itunes - that seemed to get rid of it but would rather have full resolution on the dac. Quote...

that karaokeequipment.com site looks pretty cool - good merchant reviews. And they even have the d7000's for $549
