C&C BH

I've seen this one on eBay, the C&C BK:

And I see there is a BH, as you asked about also for $99.

Zero description about these except for here:

But, I'm with you -- anyone tried either of these amps?

Please allow me to chime in here, if I may.  I came across this amp through a purchase from another Head-Fi member.  Ultimately, the amp wasn't my goal - the goal was to get a LOD cable for a Sansa Fuze and a spare Sansa Fuze, but the amp was part of the package.  My initial thoughts were that I'd quickly put the amp up for sale and not keep it for my personal use.

However, once I received everything - in beautiful condition, I might add, I started to use the amp.  After a few days, my mind was convinced that I was not going to sell that little baby at any cost... well, maybe if I were to get a few hundred bucks for it so I could turn around and buy a few more of them for my use.  I use the amp quite frequently.  Initially, it started off as my amp that I'd carry to work to power my Magnum-modified Grados with.  The amp performed flawlessly.  It lives up to its state charge retention times, too.  I charge it about once per week and that's only because I end up listening to it at night and waking up 4 hours later to power it off.

The amplifier housing is quite solid and constructed of aluminum, which includes the oval outer shell and both ends.  There's a gain switch, a low frequency boost and a 3rd switch for adjusting the sound field / sound stage.  I've rarely used the bass boost because the amp does a great job of handling the music from the source that feeds it.

There is one small complaint, though, which I will bring up as a negative item that could concern some people.  When turning the amp on, there is a slight "pop."  To avoid this, I'd suggest turning on the amp and then plugging your headphones in.

Enjoy!
