Yup, I get that.Because its depending on your electricity quality ,and the level of your system.
I'd say my electrics aren't the best - every amp I've had in has had some sort of hum and not all the same. The Naim hum needed a grounding cable, the Schiit Aegir hum needed Jensen Isolator, the Hegel required an Audiolab DC block. The weird thing was none of those fixes worked for any of the other amps. No idea what that's about. The Puritan had no effect on any of the amp's hum nor increased SQ, to my ears at least.
FWIW the speakers were a pretty decent level and resolving, Dynaudio Heritage Specials, which tend to take no prisoners with the chain, that Esotar tweeter will quickly let you know what's what.
I've seen some reviews that claim the Puritan transformed their system, (Steve Huff review on YouTube for one) So yeah, I'm either half deaf or maybe my electrics are too clean to benefit, I guess. Dunno.
