Many thanks for all the replies. A couple points:
1. I am not a bot
2. I am replacing an integrated amp so I am happy to go either with superior integrated amp, or a pre/power setup, provided they match the space constraints.
3. The GAN option sounds very promising.
4. I had assumed that Class Ds would be a step down though that increasingly seems to be a prejudice.
5. Speaking of Class Ds, one of my local dealers is pushing the Cambridge Evo 150, which has streaming capabilities (which would be a plus for my wife). Does anyone have any insight as to whether that would be a good product along with a phono preamp?
