I don't know what techno means by dissappointed.. a little more specific would be helpful. But anything else? He must have bought one made on Monday by a hung over tech. I've got the R version and it beat out the last SS amps I had in my system (Nuforce, Usher - both considerably more wattage then the Rocket) for musical weight, extension and presentation. I think it's a great amp, as does pretty much every reviewer I've read who's heard it. Add to that switching on the fly for both speakers taps 4/8 ohm and output 30 triode/60 UL, rock-solid build, American servicing and great used prices -- not much not to like IMO.
