I tried many amplifiers to drive these notoriously difficult speakers: Counterpoint, AudioResearch, and some famous transistor amps. Only the NYAL sounded comfortable---and in fact they sound not just comfortable, but glorious.
Very nice system! Those Stax F83 are a real treat to see. Very refined and extremely musical. Love the Klyne preamp and although I'm not familiar with the NYAL OTLs, I couldn't imagine anything other than a tube amp on the Stax!
