I'm not sure of the answers to your questions. I can tell you that the NAD is rated for 60 watts but repeated testing has shown it to deliver 130 watts
when using the same techniques other manufacturers use to rate their product. Like most audiophile companies, they purposefully underrate their amps. The contrast is that most amps sold in the mass markets tend to deliver a lot less than advertised. I've seen amps rated at 80 watts push out 30-40, depending on the load. Here's some instrumented testing of a Pioneer VSX-1021
that's rated for 130 watts a channel and yet only pushed out 45-55 watts when tested. Check the image I attached to this post for the picture from Pioneer's website showing their wattage claims. The NAD under the same tests showed 99-114
watts from its 60 watt ratings.
I know absolutely nothing about your Pioneer VSX-31. It is one of their Elite receivers, so it should be on their higher end. It is interesting to note that the Pioneer Elite VSX-31 weighs in at 22 lbs and is rated for 80 x 7 watts. The NAD t747 comes in at 30 lbs and is rated at 60 x 7 watts. When you consider the size and quality of the power supply needed to deliver that much power, its evident someone's specifications aren't telling the whole story. So, perhaps you are getting the watts but they couldn't be as clean as an amp with a beefier backend?
For what it's worth, I came from a Yamaha that is rated at 65 watts x 6. But, when I drove the towers, the 362s, to higher volumes the sound really came apart. It got harsh and gritty and the volume stopped getting much louder. That Yamaha had the spec's but it didn't have the power. The NAD, on the other hand, has lower specs. But, when the volume raises, the sound stays just as effortless and clean as it is at lower volumes. My wife used to complain all the time whenever a movie got louder. In hindsight, the amp ran out of steam and got gritty when the movie got loud. With the NAD, the complaints stoped because it sounds clean and smooth, even at high volumes.
I think if what I'm saying makes any kind of sense, you should order an amp with a really great back end, like the NAD t747. If you try it out and you don't like it, send it back! If what I'm saying doesn't make any sense, open another Bud Lite and don't worry about it.
