I have read comments on Audio Review that indeed Mac is using Denon transports. One fellow removed the cover of an 871 and it showed the transport sporting the Denon name. However, the electronics were Mac's own. They are owned by the same company, D & M Holdings.
Your really asking about two different kinds of sound. I've owned two complete systems, one Mc one Krell. Both are great with the Mc more tuneful and Krell more complete. I found myself turning the volume down on the Krell and up on the Mc. All this depends on the rest of your system. Unless you need DVD you should consider the Mc 201 or 301 instead.
