Small room amp and speakers recommendation

I run a Naim Atom with Totem Forest speakers in a small room and love it. That's over 5k, but Totem Rainmakers would get you there.

NAIM Atom and Vandersteen 1ci and you have $ for wire and Tidal :-) nice analog input, Schitt Mani phono preamp and away you go !!!!

I'm in the same situation, and I'm strongly consodering studio monitors; for instance Dynaudio LYD7 (or 8) or Focal Shape 65 (or Genelec or any other) who could be placed close to the wall, with a RME DAC as a pre. (The RME ADI-2 DAC Pro fs has analogue inputs) -  it has a 30 band EQ wich could cater for the worst dips in the room (I think).
I think it's easier than bying hi-fi speakers and trying to make them work in such a small space. 

Good luck - and please let us know how it works out for you.

The most important thing, especially at your price point, is the room. And there you may be in luck.

The ratio 1 : 1.56 : 1.87 simulates VERY well at 50 cubic meters. You don't have that - only about half. Still, it's a better bet than anyone has a right to expect.  I suggest reducing that 84" width to 77" with some thin bookshelves, which gives you 77" x 120" x 144".

Caution: a half inch, even a quarter inch, matters here - I just finished a room to 1/8" tolerances, and it's the best room I've ever heard. If you want to know more, PM me.
