Anyone go from a NAD and able to comment on any listening difference (Highs-mids-lows)? My NAD has been excellent performer and powers Magnepan 1.7is with ease- but always interested in finding something better since I'm on 'the upgrade road'.
I can't comment on a NAD comparison but I am sure you don't need a 20 amp circuit even though it would be a good idea. Also depends on The configuration you get. The 5400-7 should probably have a dedicated 20 amp even though I have no problems with my 5400-7 plugged in to a UPS/surgeprotector with 5 other things plugged in and I crank it to refenence and above regularly. These are very efficient amps.
