If you can find a used Peachtree Grand Integrated X1, it ticks off most of your boxes, sort of. It has a tube buffer and is Class D amplification. I like the newer Peachtree Nova 300 better. It has a really good DAC and a decent phono stage and takes up a lot less space than the Grand Integrated. No tubes though.
I recently bought a Vincent SV 237 integrated, which is a true tube/solid state device. The preamp section is tubed and the amp section is class AB with the first 10 watts in class A, 150 watts at 8 ohms, 250 at 4 ohms. It does have a USB DAC, but I've never used it and have no idea whether it's any good or not. No phono stage. It does have a remote.
