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!

Brass of course..And then proper mechanical grounding of all the boards, power supply caps, transformers and then the entire chassis. Vibration either self induced or of external influence can be given a positive relief to a higher mass..ground. Tom

Theaudiotweak: Brass? That's a surprise, I would have guessed rubber or wood or maybe glass or plastic. Do you also feel that the metal screen transmits electromechanical vibration and or electromagnetic induction? It seems like the metal screen would be a good electromagnetic sink or do you feel a polyester screen would be preferable?

The removal of ferrous materials in and around circuit boards, crossovers and speakers will result in lower distortion and a more musical presentation. Providing vibration direction,focus and relief in my experience results in a much more natural, dynamic, and open sound. Brass is my material of choice in most every instance. Tom

Mullard CV2492 gold pin cryo tubes . Somebody talk to me who has rolled a set of these into the preamp. I presently have a set of Tungsram E88CC/6922 and did not see a substantial change from stock tubes. What cha got there...?
