I recently changed from tube preamp and class D stereo amp to a integrated and so far I'm happy.
I ended up getting the Yamaha AS3200, I got it brand new for dealer cost which was a big part of the decision, but it is a beautifully made amp that sounds really great overall from bass to imaging, soundstage, smooth highs, it seems to do it all, and it has beautiful wood side panels and VU meters which really helped pushed me over the edge.
So far I'm enjoying having fewer boxes, cables, and the meters are serious nostalgia bait. One of the greatest things is the dead silence from this amp, with nothing playing you can crank the volume knob all the way to the max and nothing, not even a tiny hiss, hum, or buzz which on my previous Italian tube preamp would hum a ton if I did that.
