Best Speakers to match Ayre V-1xe and K-1xe

Haven't heard them together myself, but your gear is reputed to be something special with Thiels.

I have owned both Ayres(V1-XE,K1-XE) and loved them with both the Thiel CS2.4 and 3.7. They also shine with the Vandersteen Quatros. (my personal favorite was the 3.7) Not quite enough juice for my 7.2s or I would still own the Ayre combo.

1st off, what an amazing front end! I've found the Ayre & Avalon combo to be pretty astounding. Since Charlie Hanson founded Avalon, it makes sense. I brought in my K-5 & V-3 to listen to the Avalon NPs, and SRV never sounded so alive. People in the store actually would stop by and listen themselves.

I would also second the Quatros as a good choice. Large soundstage. My last suggestion would be the ProAc D38s. Amazing midrange, full deep bass and extended treble. The ProAc-Ayre combo is one of my favorites.

Just heard the latest speaker from Dynaudio, Sapphire, which is their 30th anniversary model and uses drivers from Evidence line. Dealer claims the sound is better than C2/4 which I don't doubt. Driven by top Plinius gears, I walked out feeling a little cold because it did not connect me to the music as much as I thought it should.

On the other hand, I really like Usher BE series. There was a demo in northern California recently and almost everyone left very impressed.

You may want to consider a speaker design that compliments Ayre's design philosophies:

Conventional designs use negative feedback to compare the output signal to the input signal, which introduces time-domain errors and other artifacts. In contrast, Ayre’s exclusive zero-feedback circuits are designed for intrinsically pure linearity, delivering performance that is coherent and natural.

IMHO, you'd want a time and phase coherent speaker to bring out the most of the Ayre goods - And I'd suggest Green Mountain Audio or Vandersteen.
