My personal experiences:
1. Stuck a GNSC statement modded 270/27 straight into Krell FPB 600. Never got on with the sound. Steve Huntley recommends they got pre-ampless.
2. Later upgraded to Weiss Jason/Medea and also stuck into FPB 600. Improvement but sound seemed to lack body.
3. Stuck an AR Ref 3, vast improvement mainly with dynamics and solidity of image.
4. Friend of mine stuck his Weiss combo into Krell evo two without evo one. Sounded vastly better with preamp Krell evo one into system.
