Should I upgrade my SLI-80 to the F1 configuration? Biggest difference in F1 is Hexfred diodes in the power supply. How much sonic difference do they make?
Are you asking about the Cary SLI-80? Doesn't it have tube rectifiers? Maybe there are SS rectifiers for the fixed bias supply; I haven't looked in mine. I got a significant improvement replacing the Sovtek 5U4g's with NOS 5AS4s.
Hi, John: I saw an upgraded SLI-80 Signature on Upscale Audio's homepage. It's called the SLI-80 Formula One (F1). It's got hexfreds somewhere. It's all greek to me(????) I'll check out those 5AS4s. Thanks, Jay
