I was looking into purchasing a Cmoy from ebay to go along with my sennheiser hd25's.

I know pretty much nothing about sound besides plugging my headphones into my Ipod so any advice on which one I should buy would be appreciated.

Here's the ebay choices...

Thank you very much.

well whats your budget? CMoys can be good for the price but other portable amps can blow it out of the water if you pay a little more

Well I would say $70.

But I'm mainlyl interested in quality of the amp and how thin it is as well as easy of use. Keep in mind this would go with my HD25's.

For that price you can get a Go-vibe 5 or PA2v2 which would be better choices in my opinion.

Is this the 25-1 or the 25-sp? If the former, I doubt you will get any significant improvement with a cmoy. The 25-1, even at 70 ohms, sounds great unamped, and does not improve signifcantly, if at all with a cmoy.

I have not tried the sp version of this phone, so can't comment on that.

It's the 25-1's. So are you saying that I wouldn't get a significant improvement with an amp?

The HD 25-SP's sound like garbage, very blanketed and muddy. But the HD 25-1's sound very very good, clear mids and highs, tight low bass.

There are afew CMoys for sale on the F/S board, do a search there and see what comes up. I found one there last week for $25 shipped CONUS.

I was researching CMoy amps, and built one myself over the weekend. It was quite fun! I want to build more, try different components, different op-amps, etc.

I for one have been very impressed with the Zero Audiocraft.

That is correct. When I had my 25-1, I did not notice a significant difference with a cmoy. I think you would need something like a RSA Tomahawk to notice a significant improvement with these phones. But ears (and opinions) vary, of course.

Even a Tomahawk is not going to blow a CMoy out of the water. Both amps amplify the signal they are given. They do not change the signal that much. I would stick with your CMoy and get better phones to improve the sound. IMO, the headphones affect the sound quality the most.

If the OP is using the HD 25-1 as a portable closed can, there aren't many better choices out there.

But I think you're right, too, in that this is one can that a lot of people seem to think is "impervious" to amping.

I got one of the CMOYs from juice2214 on eBay. The first one had a problem in the L channel (that he couldn't hear) but he sent a replacement anyway and that one is great. I'd highly recommend one of his as a decent portable amp (plus a Penguin or Altoids tin amp makes a great conversation piece).

Me too. I am glad I went for a Zero A as my first amp.

The amp seems to be very well built and there is no added hiss.
