This is the 48v 7.5A SMPS ordered from Aiyima and the multimeter I got 3 days after. Used power plug from defective laptop computer as the cord that came with the PS was flimsy. Was able to connect and adjust - to 44v. As I had no idea what I was doing, had to watch several YT videos to make sure I don't get to blow this one up.
Compared to the 32v, it was noticeably louder of course with extra oomph on everything driving my KEFLS50s. Wasn't too warm that I couldn't handle but volume was just between 9 and 7 so maybe that's one reason. Other than that i had small rechargeable fan placed near just in case.
BTW, also changed op amp to LM4562 and using an FX audio tube preamp (without the tone controls).
