My ears are ready to retire!

Been there done that too....burn out. After 50 years of tinkering and excess of $250k spent, i finally settled on a simplified Melody Audio 300b and a home brew el34 system could live with for the rest of my days. I think most people in this hobby will downsize as they see their golden years. Best of luck in your search.

Integrated considerations Belles Aria  $2300.000 and Croft Integrated $1650.00 special or Rega Elicit R $2995.00 available from Gene Rubin Audio in California

There AvaHiFi ( Frank Van Alstine) in Minnesota offers a Set 120 Control Amplifier $1200.00  solid state

Hopes this helps, never heard any of these but I have heard Van Alstine preamp and amps back in 1978 driving Magnepan Tympani 3 panels versus Audio Research tube pre and power the Van Alstine crushed the ARC better control and no silibant S's to be heard.

Chances are you won’t be happy downsizing and will go back to upsizing. 

Depends as the posts above request on what your specifics are in terms or room size and what you want to spend.

I move my bedroom clock radio BOSE wave radio down to my garage when I wash my car and I am surprised how pleasant it is for background music. Plays pretty loud without distortion.

I bet you could pick up a used one for peanuts. I don't think they make them anymore. They might only play CDs though, not sure how the product line changed since 2000....it is reliable, I'll say that and I think it can take other input sources and has a nice remote.

Buchardt A500 has all internet streaming option.
