@superhonestben Thanks for all the details. OK the GH elevator is a step up transformer. I use a Zesto Alesso SUT, and it sure makes a difference in sound with the Aphelion2, more full bodied. Played around quite a bit with setting on the Zesto also to check which combination of gains on SUT vs PS plus volume setting of pre-amp (PrimaLuna EVO 300 pre) plus resistance in SUT vs PS sounds the best to me in my system. Lots of fun!
Will keep an eye on the Whest products. But I am not in a hurry. It typically takes me a year to place an order. I am not one of the high gear turnover people. I rather think long and hard, then keep and forget about it.
