Recommendations for modern integrated with tone & balance controls other than Mcintosh

Adding to the info that the Luxman L-590axii is a hybrid A, A/B, the L-509x is also a hybrid A, A/B with the first 6 watts biased for Class A, then A/B up to its rated output of 120W into 8 ohms.

Moonriver 404 Reference might be perfect.  Got great reviews in TAS and/or Stereophile.

The Stereophile measurements section on the Moonriver was very concerning, and I concluded that the design really wasn't yet ready for primetime...

I have kept my tube monoblocks and use a Yamaha AS1100 as a Pre Amp, which gives me balance, bass, and treble for low sound output. Also is useful with troubleshooting to have an additional power amp. Only thing with the Yamaha it only has one pre out so headphone use the plug in. With the tone controls set to Zero they are bypassed.

I have similar problems with my hearing as left ear has 25%loss due to a medical condition. Since this came on about 1 year ago, I have ended up using my backup Marantz PM8006 as my primary amp due to balance, 3 range tone controls and direct pass thru features.  It is not on the quality level of a modern Luxman at $1000 but is much nicer than expected for the price.  And, with the ability to go back and forth between direct and with tone controls I can compare sounds for every disc I listen to and also adjust bass, midrange and treble and balance. It has restored my enjoyment of music and reduced the depression I felt at losing both hearing and the ability to travel due to covid after retiring to enjoy both those very things. I still miss the warmth of my updated McIntosh MC250 but there is actually more detail with the Marantz so I feel like I am getting more of the music in a different way. I did hear the PM 14 and 15 when I got the 8006 and they were very nice and somewhat higher quality I just wasnt in the place to invest that much at that point. I think they too would fill your needs.
