DK Design VS.1 Reference mkII - Optimization

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.

And you know the difference in sound is attributable to the electromagnetic waves bouncing off the top cover? How do you know this for certain? Could it also be possible that the amp runs cooler with the top off, and therefore the bias is at a different level than when the top is on? Having done bias measurements on my Class A/B solid state amps immediately upon removing the top cover (after the amps had been on for several hours), and then measuring again 45 minutes later when the amps were cooler, I know for certain the bias was different...and the amps sounded different.

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.

Honestly, electromagnetic bounce effect sounds like pseudo-science to me, but if the DK sounds better with its top off, then top-off it shall be!

Audioari1,
I also have found that the amp sounds better with the cover off.Regards,Bob
