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!

I dont think vibration is an issue with the DK amp. It is a very massive peace of equipment and there is no vibration to speak of. This brings me back to the EMI issue. The concept is quite simple, some of the EMI bounces off the aluminum cover and goes back into the circuitry, creating a sort of a negative feedback circuit. When a small amount of signal goes back into the circuitry it gets amplified again. This is the reason I believe the amp sounds better with the cover off.

What I hear is that the midrange becomes even more open and organic when the cover is off. There is also a bit more detail and texture in the bass.

If you believe it sounds better with the top off, then that's all that matters in your system.

Electrons vibrate regardless of mass. If there was no motion their would be no sound. Giving that motion focused direction and relief is the key to better sound and greater efficiency. Tom

Knowing the real answer to why? may greatly increase the application of the answer. Tom
