I would probably term NAD as neutral (in it's price range). It does not bring the music forward. Has a laid back sound that I love. I believe the Parasound A21 will go well with a TVC (passive preamp) as it has a good (would have licked higher though) sensitivity. How I wish I could afford a pair of JC1 momo-blocks
Roughly 8 months ago, I posted this on AVS; i.e. A21 (stereo 60 lbs) vs a recent (used) Sherwood Newcastle A-965 (125x7 70 lbs):
I've used the A21 for a month now (9 months now) and am very happy with it.
Pros for the A21:
1. The A21 is more detailed than my 7 channel Sherwood Newcastle A-965. Point for the A21.
2. The A21 is not fatiguing even with many hours of listening, which is a real accomplishment for an amp that has detail. But still a tie, as no fatigue is perhaps the best feature of the A-965.
3. The A21 has somewhat less speaker bass "bloat" than the A-965. Point for the A21.
4. The A21 is very well behaved. No bad behavior of any kind. No pops or ticks or hum of the unit or speakers, while running. No bizarre on/off behavior. A tie, as the A-965 is also well behaved.
5. The A21 has wonderful options on the back panel, the A-965 has none. Point for the A21.
6. The A21 is 60 lbs, vs. 70 lbs for the A-965. Point for the A21.
7. The A21 front panel lights provide more unit status and fault status.
Point for the A21. Perhaps a small point, until it is needed.
Cons for the A21:
1. The A21 does give off maybe twice the heat that the A-965 does, due to it's high bias A/AB operation; perhaps "warm" but not hot, gives a better sense of it. To me this is close, but half a point to a full point against the A21.

There are likely other more subtle issues that also favor the A21, but the above are enough to make me very happy with having gotten the A21.

At this point (8 months later), I can also add that my stereo A21 amp lets changes that I make (with either the pre or the player) come through. Meaning that the A21 is a very neutral SS amp.
