I got the Caiman MKII, and also theri new Capella headphone amp as well.
My impression of the Caiman II is that it should have a wider base of owners. The level of detail, imaging, dynamics, and analogue presentation is once of the best I have ever heard from any DAC. I only decided to really give it a try, under the Beresford very generous returns policy if I was not 100% satisfied, after I was tempted by someone on a forum trying to sell his Naim DAC. He was downgrading to a Caiman MKII after comparing the two DACs.
I did give the Audiolab DAC atry before that, but I was not impressed with the electronic like presentation from that one. The Caiman MKII is a lot warmer, with better bass and spatial separation, and even detail. The detail bit I think is down to a very low jitter performance.
I had mine delivered free of charge via Royal Mail next day delivery, which was an added nice touch. I can't think of any other item that I bought for a long while that was delivered so quickly after ordering. So a very nice touch to top it all off.
