I've had my Caiman for over a week now, and it has been playing pretty much constantly to run in.

I'm using it purely to drive my Denon AHD-5000 headphones to play FLAC files from my laptop, and I have to say I'm extremely pleased with it.

In my rather limited vocabulary, I'd describe the Caiman as having a very enjoyable and detailed sound. It doesn't seem to have a preference for any particular type of music, as I've thrown a fair variety at it. It pulls a lot of detail out of the mix, but not in a distracting way. The real benefit for me is that it has good timing and plays basslines _properly_ - this is key to a lot of the music that I'm more biased towards playing.

I don't have any of the older Beresfords to compare it with, but from the perspective of using it as a DAC and headphone amp it's great. I think my Little Dot Microtube headphone amp has just become superfluous and may end up on eBay soon

In summary - I'm very impressed with the Caiman.
