Best amp choice for Thiel 2.4

Krell FPB400CX.

I had a pair of Thiel 3.6s. I paired them with a ML333 for over 8 years. Because of a repeating issue with capacitors, I finally gave it up two years ago and bought a Pass X350.5. The thing sounded amazing right out of the box. I had thought that with my system at that time, I had pretty much "maxed" the performance of the Thiel 3.6. But the Pass brought out more details, more bass, and better soundstage.

The friend that introduced me to the X350.5 had at the time both the X0 and ARC Ref 2 in his system. The panel of judges (3 of us, not including the owner) all prefer the X0 slightly over the Ref 2. But we ended up voted for him to keep the Ref 2 because we felt that with some NOS tubes, it would probably outperform the X0. He was using one of the big Avalon speakers.

The point I am making is to steer away from Mark Levinson amps. (Except the 33 or the 33H)

Thanks for your suggestions
Pratically the best choice is to remain in the Pass family and to buy a X350.5

Has anyone matched the Thiel 2.4 with Channel islands D-200 ?
