Two people I would suggest contacing,John Devore directly as he should direct you on what works best or better...Jeff Nelson /head of Boulder amplification who arguably makes the best amps in the world and his ideas on why solid state is far superior to tube.
I’d highly suggest auditioning a Meishu Tonmeister from Audio Note UK in your system. Google the amp and read its reviews on Stereophile, and various other reputed publications. It’s a highly respected tube amp, among others that AN UK make.
