Am I dreaming?

Checked Schiit lately?

Belles Virtuoso Integrated Amp should be released soon and checks all your boxes. Their Aria integrated gets great reviews but I think the phono stage only works for MM on that one. If you aren't in a hurry, I'd at least check with Belles &/or some dealers about how close the Virtuoso is to being available...might be worth the wait, especially if its arrival is imminent.

I use a Creek Evolution 100a in a bedroom system and been very happy with it. It has a built-in headphone amp and it can include a built-in MM/MC phono stage module (though mine doesn't have the latter). Not claiming it'll better the McIntosh, Luxman, or some others you've already had recommended, but this represents a much cheaper option that still checks off all your functionality needs. Since you didn't include the budget, I figure you might appreciate a lower cost option. You could even use the Evo 50a and have all your needs met in terms of functionality. The 100a would run ~$2450 and the 50a  ~$1450 new with the phono module included...and you can also add a DAC module for even more one-box functionality, if desired.

I realize you're looking to downsize here, but by needing a good headphone and MC amp you're obviously really limiting your choices.  And what are the chances the few contenders that check all your boxes happen to match your sonic tastes or will synergize well with the rest of your system?  Headphone and phono amps are frequently on the smaller side, so would it really be that bad if they were separate from the integrated?  It would open up so many more options for you across the board.  Just trying to look at it from a different perspective.  Best of luck, and congrats on retirement!

I would have to agree with Soix.
I went the complete all in one Mac route and was very happy to start with, all those boxes and cables gone!
But then the reality started to set in, the DAC was well ok, the phono was def so so, the headphone output was decent.
But that's it, nothing was truly outstanding and did not blow me away when I listened.
Eventually I moved on through a few more integrated units until I settled on a very good one.
It does not have phono or headphone but my phono stage is tiny and the headphone amp not much larger. Plus I can if I desire upgrade these 2 components fairly easily and cheaply.
What I am saying is that convenience does not always pay, I know as have been there......

Thanks for all the replys.  It seems there can be very high quality phono stages but headphone amplication is still lacking.
