Hmmm...haw...hmmm...haw...what the heck, I might as well wade in to the bug infested swamp if only to give my opinion on how NAD sounds compared to Outlaw.
I have to agree with this reviewer's assessment of NAD's sonic characteristics:
NAD 218 THX Review The highs were not rolled, dark, or distorted, but there was a noticeable if gradual loss of detail resolution as the frequency climbed ... The thick, overripe midbass I noted in the 218 THX was reminiscent of every NAD amplifier I've heard since the original 3020 integrated ... The 218 THX's biggest surprise emerged from beneath the midbass: the tightest, most dynamic and explosive bottom octave and a half I've heard from any amplifier I've auditioned in my house. ... aside from its low-bass performance, there was no area of performance in which the NAD particularly excelled.
My own personal experience is limited to several NAD A/V receivers including the T742 and T752 as well as the Outlaw 1070 receiver. In a nutshell, the Outlaw sounds better but the NADs play louder. I had a few friends over just hanging out with some music in the background. Both of them were 'drawn in' to the sound of the Outlaw and sat down to listen to a few songs. It really sounded good --- particularly using analog inputs via the HPF/LPF 80Hz subwoofer setting. This did not happen when I had the NAD setup, however IMHO NAD seems to be in its element when played at a high volume level. If you're a bass-hound who like's to crank it, go for a NAD, otherwise I think the Outlaw would be more satisfying.
