I wanted to share my experience with the C&C BH2. I have had it for a month now and I have to agree with what everyone has said here. It really is a nice amp for the price class it's in. Interestingly I also have a WISS Audio Sound Gun 2, and I'll be darn if they don't sound very similar? Yes the WISS does not have the SF or the LF but I have found that with the LF on it adds muffling to the presentation not at lower volumes, but more at the higher ones.
Now the SF is nice and clean at any level and the WISS sounds very similar with this switch on the C&C which was interesting. Yes the WISS is a bit more ($126.00 Amazon) and not as flexible as the C&C with the additional two options, but it's really nice and clean and simple and has the same dimensions as the C&C which is nice and you don't have to wait 2-3 weeks to get it.
The WISS is as quiet as the C&C which is nice but not sure about the battery replacement. It does have two outs that are exactly the same which some people have complained they would of preferred on the C&C. I have to say that they both seems drive dual driver and triple driver IEM's that I used to test very well. Both are very quiet with no hissing until you engage the HI switches. The WISS should really be added to the list of portables to have someone with a real ear test it as see if it's another nice portable amp others may wish to consider in a shoot out.
Tested with .m4a lossless audio files with Weston 3's and dual driver Aurvana's Cardas cable via 3.5mm out.
