One was brought to the local audiophile club meet Memorial weekend (along with a Glow Amp 2), but unfortunately, we ran out of time before either could be auditioned. I did read the manual and this does appear to be about as close an SS version of a SET tube as I've seen.
Whether that's good or bad would depend on what one is trying to accomplish audibly in ones system, via what method.
cheers,
