Bias for Jolida 502 P Amplifier

Just got my new Jolida 502 P yesterday and I'm enjoying it a lot - great sound! (Thanks Wolf and Jedinite for your posts re the Jolida amps) I'm surprised at the amount of bass and slam I'm getting with my Magneplanar 1.7's In fact I'm thinking that for a lot of music I probably won't even turn on my HSU sub.

On setting the bias - how important are small variations? When I got the amp I checked with my multimeter and the amp was set at about 560 mv for all tubes. Moved the bias back to 500 mv per the manual but I'm not sure if it really matters all that much for these small changes? How critical is this?

In my opinion the kt120's sound much better in the 502p.The 120's are more extended top to bottom with with better separation and a fun energetic presentation .The Gold Lions have less extension top to bottom and seem just ever so slightly congested when compared to the 120's the GL just seem more laidback and relaxed. FYI I had the gold lions in for the last 6 months and the 120's for about a month now.
