Interesting DIY AMP from China on Ebay ( need advice)

post #1 of 11
Thread Starter 

Hello,

Thinking to get my feet wet with DIY. This AMP get my attention but being total newbie I probably need advice form Gurus.

http://cgi.ebay.com/HD8-HEADPHONE-AMPLIFIER-BOARD-KIT-Ref-beyerdynamic-A1-/220749148830?pt=LH_DefaultDomain_0&hash=item3365acb29e

I already ask this guy for details but he didn't give me much info on this. Item description pretty useless .

So, I just wondering if anyone can tell is it worth to try with this one or look for something else. May be it's silly to ask for opinion based just by look but anyway will very much appreciate it.

Thanks.

For $50 delivered it looks pretty good. 

 

You might later decide to upgrade the op-amps which will be easy as they are socketed.

 

Edit: Oh, wait - I just noticed: "A FINISHED AMP FOR YOUR REFERENCE(NO CASE, TRANSFORMER AND HEATSINK INCLUDE IN THE LISTING!!):"

The ad seems to mention it is a rip-off of the beyerdynamic A1.

I think we frown on "for profit" clones around here...
