NAD C320BEE Vs Audio Refinement Complete

The Nad is more vesitile (main-in/pre-out).
The Audio Refinement Complete has no pre-out or main-in.
The Audio refinement Complete Alpha (latest itteration)has pre-out but no main-in.

The AR is a much better amplifier though. It may say 50watts but it is a very beefy 50 with a steep slope to the volume pot. I have it on a pair of speakers that are a dreadfully inefficent 86db. At about the 12 o'clock position they are as loud as most would want.

The AR just adds another layer of depth to music. THere is more air around instruments and voices.

Good luck!

Do not know anything about the AR unit, but I have an NAD 320 BEE with a pair of Odyssey Epiphony speakers. This is a very musical combo - I use it for Home theater. I used the Epiphony in my main system for a while - they throw a huge soundstage and have good bass for the size. They are $600.00/pair through Odyssey Audio direct.
Hope this helps.

I have heard the NAD driving some Proac floorstanders in a large treated room. It sounded great with the sound quality also impressing the owner who was doubtful about its ability to drive them properly (home based sales guy).

I have a complete alpha myself and all I can say is that its absolutely magical for me. I've had it for nearly 2 years and I still can't believe what a joy it is to listen to. Great bass, sparkle, soundstage, pace, rich tone and just enough softness to cover up imperfect recordings.
