Shuguang KT88-98.What about rolling input/driver tubes? Taking the bias up will sweeten,down more SS-like.Experiment with your biasing first.

I have rolled the input and driver tubes already. The stock tubes are probably Shuguang KT88s. I am using cryo'ed Gold Lion KT88s and they do sound better than the stock tubes.
I found that it sounds more SS like if I increase the biases. Is this common? With higher biases, they sound more aggressive, extended, etc....
The manufacturer is not responsive. I had asked a few questions through their importer, but got no answer.
Vett93: YES- Sometimes a manual will include a range, rather than one specific setting for your bias adjustment(ie: Cary SLM-100= 150 to 175 mA). The upper limits of that range will yield a more dynamic presentation, and sometimes sibilance or glare can result also(more Solid State-ish). Of course- the other direction takes one into the "more relaxed presentation" zone. Hopefully: Somewhere in the middle- one will find transparency, with the right tubes/equipment.
