After installing the foobar plugin I've noticed some CDs I ripped long ago showing up as HDCD (with PE). When I try decoding sample tracks from them with eac3to (using -decodehdcd) they all come up with a constant/average bit depth of 17.   Is something wrong with the way eac3to decodes them...

Your photos are great. I can't even pretend to understand what you've done but it helps to see the finished work.   I somehow missed hearing about removing those caps at C8 and C9. Does that have a similar effect to removing the ones at C6 and C7? I'm wary of those just in case my amp (or...

Thanks for the photos It helps to see the actual mods.   If I rolled up strips of tin foil and taped them in place with insulating tape, would that short out the caps without using solder?   Ideally, I'd just like to see if/how the mods work without making any permanent or visible changes.

What are the caps there for originally? Will removing them have any knock-on effect electrically?

Do you mean all 4 of the caps (as seen in this pic) or just the 3 that sit between the TDAs? I still have to try removing/shorting the output caps but if you think removing these other ones helps the sound as well I might give that a try too.

I might try this but how can I tell if an amp has input capacitors? Short of opening it up and looking (and even then I wouldn't know what to look for).   Quote:  

I dug out a 9v 500mA PSU and the DAC ran just fine with it. However, the PSU got quite hot after a while. I'm mostly using a 9v 1.2A regulated supply for now. It's a brick but it works fine. The 12v PSU that came with the DAC was rated 1.5A.   This is with the white PCB DAC with the 15-18v...

I briefly tried the PSU it came with but didn't like the buzzing noise coming out of it. When I cranked up the PSU I have been using to 12v I noticed the unit got warm fairly quick. So I guess I'll stick with 9v.

And I'm still running mine on 9v. Maybe it's not a good idea to be using such a drop in voltage (?) but it seems to be working fine.   Quote:  

Are you using the 12v adapter it came with? I see the AMS1117 there is 5v, same as mine.   Quote:

Yep, that's it.   Quote:

Yep it came with a 12v adapter. I emailed them to ask about the different components and from the broken english reply I gather they may have made some improvements to the design. They recommended I use the 12v adapter that it shipped with, but I ran it for a few hours with a 9v one instead just...

I got it from here   Quote:  

Quote: Mine also says 15-18v on the DC-IN. The PCB is white and under the heatsink is a label saying "2010.01.22 ver 01".   It also has the 5v regulator :(   Any idea if this is an older version of the ones with the blue PCB? What does the label under the heatsink on the blue PCB...

Quote:   I've used it a little but I'm wouldn't be comfortable running it 24/7. It works well though :)   I'm using a phone for my portable music these days too. Sounds good to my ears anyway. Quote: If mine has a 5v regulator when it arrives, will it run OK so long as I...

Hi all I found this thread when I was looking for a cheap and good DAC for my PC here. After reading through the first and last few pages I went ahead and ordered one of these ones. I'm just a little concerned about the overheating. Will this happen even in a stock config? I'm not going to be...
