Best possible separates for Thiel CS 3.7

Ayre R-series
ARC Ref 6 and Reference 250
Aesthetix Atlas and Callisto

That’s a lot of coin for Thiels. Make sure you sign up for Tom Thiel’s XO upgrade when he has one! A tweaked CS3.7 driven by these pre/power combos would really sing!

@beetlemania yes i recognize it's a lot of coin for an only 15K speaker but my goal is to push the limits of the 3.7s since i cannot convince myselt to change speaker brand in the future, that's how much i like Thiel speakers.So the only way to upgrade is to get the best possible electronics out there to drive my 3.7s. and see how far they can go.By the way i can confirme you that the Aesthetix Atlas monos and callisto is awsome pairing the 3.7s, i've auditioned this set up.I have been told the Aries Cerat pre-powermonos combo driving the 3.7s is world class!

Ayre R-series is unfortunately to expensive in Europe at €67K.

I agree, the CS3.7 is a seriously good speaker. I think Tom Thiel’s forthcoming XO upgrade will push it to the next tier.

The stereo VX-R plus KX-R might be closer to your budget limit. The 5-series sounds nearly as good, IMO, but not as much power. Or MX-R for the power combined with KX-5 pre-amp will come in under budget. Many, however, think the KX-R is Ayre’s best ever product. A KX-R plus Atlas would come in under your budget.

Lots of good choices with that budget! Have fun!

They're a difficult load, I wouldn't put tubes on them. For amps I'd look at Bryston 28B Cubed, Pass X350.8/X260.8, MOON 870A, Audia Flight Strumento 4, Accustic Arts AMPIII, BAT  VK-655SE, warmer and smoother SS in general.

For the remaining budget I'd pick a DAC that could drive the amps directly if you only listen to digital.
