DK Design VS.1 Reference mkII - Optimization

I would like to know what tuning, customizing, hot rodding, tweaking, what ever.. that you owners of DK Design VS-1 MK2 are using to bring out the best in this amp. It seems to be responsive to changes in interconnects, tubes, power & speaker cables, speaker dynamics, etc. most probably to both the positive and negative.

Please share your work. I would like to know what improved it's performance, what caused no real change and what made it sound worse. Thanks in advance!

One tweak that I tried that makes a BIG difference is playing the amp with the cover off. When the cover is on, electromagnetic waves bounce off the metal and back into the amplifiers circuitry. When the cover is off, you will be surprised how much better it sounds.

Tvad, I am fairly certain that it is not due to the cooling effect because the amp doesn't get very hot in the first place. And it makes logical sense that the electromagnetic bounce effect is at play here. In any case, whatever you want to call it, the DK amplifier sounds substantially better with the top cover off, try it and see for yourself.
