Thiel 3.6, what will drive them best?

"Cheap" means $10,000 for some people and $1,000 for others.

Also, how loudly do you like to listen? Do you value lots of bass? How large is your room? What is your preamp? Choosing the right amplifier for you and your system will depend on these answers as well.

Alas my budget is lower than the lowest figure you mentioned.

The room is an "l" shape 13 feet wide, 22 feet long as
shown in the lower drawing. sp denotes speaker position
and the o's denote the open entry to the kitchen and the lp
represents the listening position. All the "." are used to reserve spacing as the Agon editor compresses text.
The ceiling is 8 feet.

Thank you,

B&K M-200 mono blocks have the power and are inexpensive. Usually around $800 in good condition.

Happy Listening.

How much lower than $1000 is your budget? $500?

EVS100S ICEpower stereo amp from Ric Shultz is $800. Same price for a pair of EVS100M monoblocks.

I have no idea how they would sound with the Thiel speakers, but the amps come with a 30 day money back guarantee, and they are certainly inexpensive for audiophile amplifiers.
