Classdaudio vs Channel Islands amps


I was wondering if anyone has heard any models from both Classdaudio and Channel Island amps. I searched the threads, but I couldn't find a comparison. I want to know how the two brands compare in terms of sound, durability, and build quality. I know that Classdaudio builds their own circuit board while Channel Islands use Hypex. I would appreciate any information.

Are there any class D amps that have a high bandwidth? Not all manufacturers publish this information.
Parasound uses Abletec amps in their multi-channel Zamp Quattro amplifier. TEAC uses Abletec in their AI-501 DA integrated amplifier.
Patrik Bostrom has filed six patents in the U.S. patent office on his Class D technology between March 2011 and December 2012.
So what, the M amps cost $45,000 - unless the technology trickles down the vast majority of folks won't be able to avail themselves to this
Now now Facten..I was just answering Izora's question. You are right that the majority of folks won't be able to avail themselves to this..after all..Bill Gates has two M-Amps in the trunk of his Maybach Landaulet. (just kidding)..
