The Cherry and 4800 amps have sounded great in my system during long and short borrowings, respectively. Powering VonSchweikert VR4JRs.
Although my system is not the same as it was when I owned the CIAD200s or borrowed the 100 watt Rotel ICE amp, I feel that the DAC amps sounded better than I remember the other Class Ds sounding.
Gobs of power yet very clean w/out being etched. Complete control top to bottom, soft to loud. Not based on ICE or UcD, they are a proprietary design.
There is a new version of the Cherry coming out but I have not heard it.
(Disclaimer - I'm getting to be friends w/ the owner/designer, so take the above as you will - Won't hurt to check them out though)
