Hi Ron.
I did acquire both psus at the same time.
Due to both of them needing 60-80 hrs burn in to fully open up, I did spend some occasions going back to stock psu for tt motor whilst sticking w the psu on the SG.
I can assure you it is dead simple to gauge the impvts wrought by both psus, and solely to the SG.
As I’ve now exceeded 80 hrs, the changes are profound and ongoing.
What I’m particularly getting as an impvt over stock wall warts and RWA batt psu, is amazing imaging, stage depth and airiness. A result of massively reduced noise. Truly adds to the whole listening experience, and is making the SG a wholly compelling transducer.

Re the RWA batt psu, it sounded very good (not as good as Peter’s psu, but still excellent) when it worked. But it often didn’t work, and once tripped the energiser necessitating return to the factory.
The issue seems to be that even though the SG is nominal 24V, I believe there is some variance +/- on this figure on R and L channels, and get this incorrect, and the energiser trips leading to potential irreversible failure.
You can quiz Vinnie at RWA about this. On two occasions I had to send both energiser and his batt pack to him. He had to configure a twin battery system and needed the energiser to measure both channels. Unfortunately even despite this switching the system on and off left tripping things a major risk. A shame, Vinnie’s efforts were much appreciated.
However I now have the dream psu to the SG, multiple power down/up during the burn in period not once risked tripping, and the SQ is significantly in advance of the RWA twin batt psu.
