Need Kt88s Genelex? or Shuguang?


I'm looking to upgrade my Winged-C KT88s in my McIntosh MC275 and keep them as back-up. I was tending toward the Genelex which some recommend highly but have also read several reliability problem reviews. The Shuguang sound competitive.
Any suggestions? Which are more reliable? Which sound best?

Thanks.

Quant100, The pictures posted on their website showed the volume control knob had a blue led on it to indicate it's position. The amplifier I received from them had no led. Shuguang did about 90% of a good job. The amplifier was advertised as having high end audio components. It does, now that I have replaced the cheap coupling caps with polyproplene caps and beefed up the power supply resistors with wirewound non inductive resistors. I was disappointed with Pacific Valve but not with the amp. With the upgrades to the components and tubes the amp performance is well worth the costs.
I am running Audio Valve Challenger Mono Blocks which are auto biasing and can use EL34’s, 6550 or KT88’s. The wattage also changes with the type of output tube; the real negative side of this is that each amp takes (6) SIX tubes! When you are buying Genalex Gold Loin KT88’s x 6 matched prs that is $550 BUCKS- well call me stupid but I dropped it for 12 bad boys and it was well worth it.

My amps came with Electro-Harmonix EL34’s and putting these bad boys in was a huge improvement, starting with just plan more power and with power comes more AC needed to keep the room cool and believe you me it sure gets hotter now; then a much bigger sound stage more controlled deeper bass. The EL34’s have a real luscious mid sound but the KT88’s really rock, especially with Swing Jazz (Big Bad Voodoo Daddy) and Blues (Buddy Guy). Well worth the investment for me, however now I got curious and went and picked up 12 Ruby Tubes (6550’s) and $250 less.

No issues at all so far with my KT88's they have done nothing but performed admirably
