Basic integrated amp for $700-$900

Ditto on the Musical Fidelity M2si from Upscale. Bought one last fall and could not be happier. Really don't think you can find a better bang for the buck in a new integrated! I use it with the Schiit Mani, Modi, & Vali. I've owned much, much more expensive separates over the years, but am very happy with this set up. I am with you on downsizing and simplifying. It's about enjoying the music, not obsessing over gear!  If you are looking used, then the options are wide open.

+1 on the Rogue Audio Sphinx - 1 or 2 . Version 1 is obviously  less costly and the phono was not nearly as quiet as the 2  . I have had and enjoyed both . Still have the 2 . You don't need the phono but maybe you will like the Rogue better and will sell the Schitt. If not then don't use it. Used it fits your budget and power needs. Runs cool and is as simplistic a line level gets. 

I agree Tlinkie.

Thanks Canerod for your personal endorsement of MF and simplifying too, plus the match with Schiit and MF products.

Firberger, though I thought about the Sphinx years ago, now I’m not sure I want an amp w/ class D amp and on board phono.

It's a little above your budget, however this amp smokes the Sphinx V2, and many others in the $1K category. It's not even close. I owned both for a fair amount of time. You have to step up to $2500 integrateds like the Parsound Halo to match the sound quality of these Sonys. These 39lb. beasts are built like tanks - even the bottom plate is thicker than that of some $5K integrateds, and I'd swear the binding posts rotate on ball bearings - the best binding posts I've used by far. The noise floor of these units (like many Japanese brands) is incredibly low, thanks to the floating ground design. You won't find that low a noise floor in 90% of other offerings (I went through an integrated swapping phase for almost 2 years). It meets all your criteria: silver face plate, no unecessary frills, no DAC or phono stage. Also allows for power-on via remote control - a feature you don't realize you want/need until you no longer have it. The same goes for remote volume control, any integrated that doesn't have that might as well be a paperweight IMO.

The only real downside is they run quite warm so they need plenty of venting space. 

Rega Brio, the new one that came out couple of years ago. Very analogue like sound. I use it in my attic system with Rega Dac-R and ProAc Tabellete 10 signature
