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

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. 

Good to hear you are happy with the Lux. I too was looking to upgrade and looking at Belles Aria Signature. However, 2022 stock and bond market declines have put that on the back burner as I am focused more on just maintaining our lifestyle. Never working anywhere long enough for a good pension has me managing assets for income. Luckily I always invested bonuses etc so we will ultimately be fine but my income plan crashed with the market as bonds and stocks both went down. I will have to live vicariously thru others like you for awhile. Enjoy your new amp.
