If you really want to downsize and still have top quality, world class sound you should have a look at Devialet Expert Pro 220. It's AD class hybrid int amp (Analog Digital Hybrid - class A acting as preamplifier/driving stage and D class providing power in the output stage) . Apart from great DAC it also has a really good highly configurable (MM/MC) phono stage so you don't have to drop the TT. As for the speaker I think you should have a go with already mentioned above Boenicke W8. They are really tiny floorstanders with a huge sound. And yes, they literally disappear in the room.
All the best mate.
