It would certainly be interesting to hear the two together. My experience is Arcam and Rotel are opposites as far as their sonic presentation. Maybe this would compliment each other but I have my doubts. I have a Sheffield Labs cd, James Newton Howard & Friends, that I have had for years and played through many a systems. On an all Arcam system this cd had the fastest attack of any system I've yet to hear. The kick drum hit unbelievably hard. This cd played through an all Rotel system made it sound very laid back. It was pleasant but it sounded like the band cut the tracks after being just woke from a sound sleep. My preference is the quicker more dynamic sound of Arcam and personally wouldn't degrade that by mixing the two brands. As told by me, Arcam is one of the best values going in cd playback. Their ability to reveal more detail from the disc and give that detail a more realistic presentation puts them ahead of the competition. One may prefer Rotel over Arcam, that's understandable, but not to be able to hear the difference between them or other brands is truely unfortunate.
