Yes there is snobbery and the RXV2700 is a very good receiver and may sound different than the Arcam. Different does not mean better necessarily, just different. I am a Denon guy, so I would go with a Denon 4306 or 4806, but be sure to leave some money in the budget for room treatments, that is where the real SQ work is done IMO. The receivers play a much smaller role in SQ. If it comes right down to it, buy the less expensive receiver to open up funds for room treatments.
