Interesting thread. I have a Shunyata Denali power conditioner and have had an Luxman L-507ux MK2 integrated amp plugged into it since purchase. I’ve had the same performance described by jsalemo277 above. Having never tried plugging the amp into the wall directly I have no idea if the less restricted dynamics ghdprentice described of might be obtained by doing so.
So I’ll try that out tomorrow and see. The pre-amp portion of the integrated might be negatively impacted by decoupling it from the Denali, so I’ll try and notice if there is any noticeable issue there as well and report back.
