Best Integrated Amp for Thiel CS 2.4 Speakers


I bought a pair of speakers 15 years ago and the Accurus DIA 100 amp I had started popping (and wasn't that great anyway).  I put the whole thing in storage. Now I want to buy a new (or demo) integrated amp.  I am not opposed to pre-amp but that makes it that much more challenging.  I am willing to spend about $4K plus cables.  I listen to the usual - 70's rock, lots of instrumental, trip hop.  I do need solid low  bass.  I barely used the speakers, I don't want to sell them.  Any suggestions?  Thanks.

I haven't heard it but the Technics SUG-700 integrated (based on GaN tech) might be awesome and for a lot less than your budget

I own a pair of Thiel 2.4s. I don’t think they need as much power as stated above but I run them currently on 450 watts lol. 
But really they don’t. I have run them on a few different amps (McIntosh MC462 at the moment) and they were fine off 100 watts. 
I would just stay way from bright equipment as the thiels lean toward brightness depending on the room. I did not care for them on class-D amps. Too cold and sterile for me. 
Don’t forget to play with toe in. They were designed to use very little toe in but i find the center image suffers that way. I would toe them in just enough for the center image to fill and stop there.
