Well I have had the upgraded p.s. running in my system now for over a week. I got into this upgrade by accident, having purchased a quad of Valve Art 350B tubes only to discover that the stock p.s. could not supply the higher filament draw. I have not changed out my WXT+ ( Blair's #1 tube) in my NS40 and to my amazement this upgraded p.s. has had me listening to some of my fav cds all over again. There has been an appreciable increase in micro detail, the bass is cleaner and the highs are as crisp as I like to hear them. All in all I have been listening to cds and am hearing nuances and detail that I have not heard before. I believe that my recent acquisition of my Tekton Lores, which have been lauded for reproducing musical detail has allowed the improvement in the p.s. to be heard.
My only regret is that I did not order the unit in the full size chassis and with the mahogany wrap to match my amp. Sitting below the NS40 it would have been awesome to look at and hear !!
