DK Design VS.1 Reference mkII - Optimization

I have to agree with Art it sounds much better when left on. Besides tube rolling (I use Mullards)I put ERS cloth around and on top of the transformers which helped flesh-out the midrange and opened the soundstage noticeably. Check out www.Tweekgeek.com for the ERS cloth.

Jomoinc, ERS cloth on the output wiring may help - I will may try that. The power cord makes a significant difference too. I was using a ZCable Cyclone for awhile which sounded VERY nice which it should since it cost more than the amp. I now use a ZCable black lightning which solidified the bass a little more and took that last bit of edge off the upper mids and lower treble which may have been tube glare in my system. I've also used SignalCables basic power cable on it which was ok but it didn't control the bass as well as the ZCable black lightning.

Jomoinc, yes the Black Lightning is "only" recommended up to 200 watt amps but I would totally agree with Mark that its the quality of the power cable not the AWG that counts.
