Received my Super 8XRS a few days ago. Had Louis use Canare Star Quad 4S8 for the internal wiring to speaker posts. Then I made my own Canare 4S8 speaker cables terminated with banana plugs and RCA. Testing direct Chord 2Qute DAC driving the Super 8's, 2Qute is powered by LPS-1, streaming direct USB from a standard home base computer with JRiver, switching power supply (will be a pico-itx powered by linear PS in the future). Not optimal, but okay for the current location away from my main home for testing.
Results with little break in, fantastic with 2Qute, less than a watt, driving the Super 8's. Tried a used Bantam Gold amp I picked up, wasn't even close, the 2Qute direct to the Super 8's is superior in sound quality in every way. But that was with direct AC power via switching power supply to the Bantam Gold, will try again once my Paul Hynes SR7 MR4 12V comes in.
The Super 8XRS are just what I wanted, highly efficient speakers, with superior sound, that will allow me to bypass the separate amp/preamp and get my entire digital system off the direct AC grid with high quality linear power supplies that disallow AC leakage. Thanks Louis!!
