Levinson No. 23 with Thiel 3.6?

A nice high powered VTL tube amp with enough power in triode mode...

I would say you are ok with your levinson amp given that you are not going to be listening at high volume levels most of the time. Thiels love power but more importantly they love quality power, which levinson is, and will let you know if something upstream is not right. Also your room sounds in good shape both in size and accoustics so you should be good there. If you are looking for detail, soundstaging and imaging the Thiel 3.6's will do that in spades.
I do not know what your pre-amp is but sometimes Thiels can be tilted toward the bright side. I use a Conrad Johnson premier 16 tubed pre-amp along with a CJ ss MF2500 amp and have no issues with brightness. My soundstage is wide and deep with loads of detail. Hope I could help. Good Luck

The only amp that managed not to drive the thiel speaks was a air tight 8 watts per chanel into 8 ohms. they damaged the surrounds of thiel 2 2 customer. I have also auditioned pass labs x-150 w/thiel 7.2's in a dealer showroom. the room is 20' x 60' x 22' ft high no problems at all beautiful sounding. thiel recommends at least 50 watts per channel for any of its speakers. while waiting for my amp and other components i was burning in my thiel 2.3's with/a 35 watt denon receiver. was fine no problems.

my system thiel 2.3, pass labs x-350, x-2, sony scd-1, theta gen5a
