I was listening to some of John Hopkins Immunity and had the same impression. The amp remained in complete control in even the densest of passages, many of which have very deep and textured bass. Comparatively, the SS supply can sound a bit overwhelmed and edgy. Additionally, I would add that there is absolutely no sense of harshness at the expense of greater spatial separation. In other words, nothing sounds even remotely artificial. It comes across as superbly transparent and smooth...really a wonderful presentation.
BTW 3/4 volume? My eardrums would be blown back in to my skull at that level.
This is via JRiver using their volume leveling turned on which cuts the volume back considerably across the board. I use iTunes at work and the same volume setting at 9 oclock on the WA7 using iTunes is 12 using JRiver. Cuts everything back a good 25% or more i'd say. Really wish it did a better job of volume leveling across playlists. It basically says 'I don't know anything about what is coming up so I will just cut everything back 25%'.
I am sure the amp has different characteristic curves at these higher volume knob levels needed to counteract the gain reduction of the sw leveling. I would really prefer they offset the sw reduction per song by boosting it back as averaged across say the next 5 songs in the playlist but this is something I have argued with JRiver about in the past with to no avail. Their argument is to just turn up the amp volume believing it doesn't affect the end sound. This is where we disagree. However I can't really listen to music with it turned off though, just too much fiddling with the knob every other song is a complete distraction.
