jaxwired:Here's the difference. I regularly post on several different forums. The subject of NAD comes up occassionally on all of them. Everytime it does, people come out of the woodwork to comment how great their amps sound. They have very few unhappy customers. NAD amps sound fanstastic for the money. People often move on to more expensive kit, but they always remeber their NAD gear fondly. Now obviously, this is unscientific and anecdotal, but I still think it speaks volumes for NAD amps. Overwhelmingly, people enjoy their music when they own NAD. Rotel is more of a mixed bag. I'd recommend NAD over Rotel everytime. Rotel is miles ahead of NAD in appearance. That's about it.
Your comments are very valid - like you, I like the Nad very much and thus cannot say anything negative about their products.
When I upgrade my system, I will have the same affection towards my Arcs and will probably refer to Arcam as and when, because, like the Nad stuff, for the money, there's very little to moan about.
However, when I've compared Rotel and Nad in the past they are two different animals: The nad is dynamic and errs towards the warm side of neutral; detail levels are very good indeed. The Rotel, on the other hand, has all those sonic virtues, but with added pace. It produces a rapid sound that, metaphorically speaking, has your body tapping with shear pleasure.
Plus factor in it's almost twice the price as the Nad. The other downside to Rotels, in my experience, is they demand a bit more care when system matching.....and I think this is why many people always refer to the Nad with fondness; like the Arcam, it'll pretty much sound impressive with a wider range of equipment.
