High end bookshelf speakers for Small room

I have a Luxman L-509X integrated amp, and it drives my KEF Reference 1 Meta speakers brilliantly in my 13’ x 13’ room. I have an equilateral 10’ triangle of speaker distance from each other and the MLP. The imaging is completely separated from the speakers and almost entirely behind the speakers. It’s just uncanny.

I forgot to mention that although the speakers hit a solid 30hz in my room, I do use a JL Audio E112 subwoofer to augment the output below that.

2 cents time: S-F Electa Amator or Raidho C or D series

The Boressen C1 16 k monitor is exceptionally good if you have the budget. Otherwise the X1 is half the price is very good. The room you have 13x14 is just about right. I have the x1.My x1 will play rock , classical , jazz effortlessly.

OP,with your room size it would be wise for you to check with TAD before laying out $15K on a speaker very likely to overload the room...
After you do find they simply won’t work in that small an environment, look at the sealed cabinet design of the YG Acoustics Tor or Cairn...
"The TAD Micro Evolution One (ME1) speakers are best suited for medium to smaller sized spaces. They can fit in rooms that are roughly 11’ x 17’ to 17.5’ x 26’. However, they are not recommended for filling very large spaces.

Here are some tips for setting up TAD ME1 speakers:

• Position: Place the speakers about 4’ from the wall behind them to avoid adverse reflections.
• Separation: Space the speakers about 8’ apart.
• Distance from listening position: Position the speakers about 9’ from the listening seat.
• Toeing in: Toe the speakers in toward you."

Vandersteen Treo CT. They don't take up any more floor space than a bookshelf/monitor speaker on a stand, and can be placed very close to the front wall.
