Hi everyone, how does cmoy look? This seems to be the only cmoy on ebay nowadays :/

 

[Sinbios]

It looks pretty neat, but can only take one 9V battery. 3300uF caps? WAY overkill. At that size, they're probably pretty low quality too. No idea how good the opamps are.

 

[skybl4ck]

Well I'm really trying to find a nice portable amp to get my feet wet in. Are there any that you would recommend under $100?

 

[jerb]

what headphones you got? the go vibe is nice

 

[skybl4ck]

I'm actually looking for headphones, too. Hopefully also under the $100 mark. I was looking at the Ety ER6 & Shure E3c's.

 

[skybl4ck]

I think I might just get a go-vibe V3

 

[Sinbios]

The Go-Vibe might be nice and small, but it's still an unbuffered cMoy design. I'd recommend that you get a nice MINT instead, as one could be easily be had around $70.

 

[skybl4ck]

where can i find one of those?

there's mine.. kinda looks cheaply made and nothing to hold the 9v battery (it gets a bit loose).

btw, how much better are the mints?

Well, I just won another auction for the same cmoy. I bid too much on it and went to 52$, I didn't think I'd win! Oops. I will hook this amp to my 595's went it arrives and give you a full detail on the sound quality. The amp having the ability to plug into the wall is a definite plus.

I really hope this amp does something for me, I had a super dual that I didn't really notice a difference between using and excluding it from the loop. I sold it for this reason and the volume control (not a fan of a 'switch').

The MINTs have output buffers, which increase the current it could put out, and also get rid of thermal feedback.

And how does that make it sound better?

I have a MINT and a Headsave Classic. The Classic is also designed by Norm who's designed the go-vibe. And doesn't have any buffers either (at least not like the one in the MINT.) but it sounds a lot better anyway. With Grados non the less.
Wish I could have a listen to the go-vibe and see what sounds better a MINT or a go-vibe...

 

[afobisme]

another question: how good are the headroom bitheads? they work as sound cards too, so i would no longer need my soundblaster audigy 2 pcmcia right?

The OPA627's could put out 45mA per channel, while the buffers raise that to 250mA. 45mA may not be able to drive low efficiency headphones as well. Reducing thermal feedback would reduce distortion, I think.

Thanks for the explanation. I have had no trouble with any headphones I've tried with either of my amps but then again, I'm a low volume listener so I haven't tried to push the amps to their limits, I think.
