wow, I love the red, blue and silver. Here's my black Caliente, looks like all the others:

I'm listening to 'United Abominations' and my HD650 sounds AWESOME!!!
I don’t care what other people say, this headphone is NOT slow or unsuitable for metal, I think rock fans will be pleased with the Caliente-HD650 combo, I know I am.
I’m hearing beautiful guitars, full rhythm guitars and bass, snappy drums and clear strong vocals. I think the highs could be extended just a tad, I’m waiting to see if burn in opens them up a little bit more. So far I’m very pleased and I’m certain this is an upgrade over my Perreaux SX-1.
Good news for Grado fans, my SR225 sounds really good with the Caliente as well, lower guitars and bass are a little more present now, same great mid guitars and airy feeling, this is the fullest I’ve ever heard my Grados sound.
It still sounds crunchy but more chunky.

I’m keeping the volume pot between 8 and 10 for the Grados and 9-11 for the Senns, anything more is too loud for me. I have no channel imbalance even at low volumes and I like the size and feel of the knob.
Overall I’m very happy with this amp, it was a good purchase for me and I don’t see myself upgrading anything for a long time.
