What power cable for DAC?
Dave just curious, have you tried the NRG-3 on other non digital pieces of equipment with the ferrite magnets taken off? You might find the power cord sounds better. 
ARC VS-115 Amp with new KT-120 Tubes
Bias is set to 65mV. There would be no overheating issues as ARC said that it's ok to use those tubes in that amp. Issues may be with much older product and/or the tube not fitting under the cage. Most output tubes require a break in period and th...

Conrad Johnson MV60SE vs. Audio Research VS55
As someone who has done these upgrades the C/J sounds excellent. Coupling cap upgrades are always nice provided the caps used are complimentary. It does take some time for those caps to break in however.
