From amp w/ "bare wire" output to headphones...

[lordroy]

So I have the signal coming from my computer, to an Amp (PFA300). The output on the amp is for bare speaker wire (would normally power a speaker either in a car or home stereo system). I would like to find some adapter that would convert it to a 1/4 jack for my headphones. I have seen this setup before, but I dont know what to look for... any ideas?

You can't easily. Those amps use a tripath chip, with bridged outputs, so you cannot tie the - terminals together. Doesn't work thus for headphones with common ground.

So that's it then? No real (easy) way to do this then??

Don't even try, you will most likely damage the amp.

You can pick up a headphone amp pretty cheap. Your computer probably has a headphone output anyway? Unless you have fitted another soundcard.

Most of the headphone amps I have seen are USB and wont use my soundcard (Asus Xonar). I want something that will go from my computer soundcard -> (amp) -> headphones... not something to replace the soundcard itself.

I found this in less than 30 seconds, they have a US site and you can probably buy from Amazon.

Looking for something a little more... desktop friendly (not portable)... with a volume/bass/treble control knobs maybe... something with power NOT from my USB port...

I appreciate you doing some bit of research, even if your reply was a bit snarky.

Which Xonar do you have ? Some have pretty decent headphones out.

Otherwise, in order to help you, we'll need to know: the headphones you use and your budget.

I have the Xonar DG, and while it has decent amp out for headphones, I need something to control volume/bass/treble (not the software). I am replacing the in-line volume control cord.

I am also planning on replacing the headphones soon as well, so this should work for a general pair. Maybe going the Koss ProDJ100 Headphones (with different pads) or perhaps the NVX Audio XPT100. I have yet to decide.

For the budget... well anything over $50 is more than I want to spend. If it is gonna cost that much I may just re-purpose my old Sony STRDE597 receiver to be my headphone amp.

For under 50$, have a look on ebay. Not many amps with treble/bass controls though.

Either a chinese thing (plenty of ac powered ones on sale, especially some using tpa6120a, which is a good chip for a start).

Or an used amp geared towards musicians such as the art headamp (at the limit, the berhinger ha400).


Edit: that assumes you don't want to diy ?

I think I will just use my receiver. Thanks anyway.
