Same here, 10 minutes or less. I have the Everest on its own platform (plenty of room to put the Everest-X on the same platform), one Sigma v3 ground cable to an Altaira chassis ground hub and two others coming in from the two Altaira SG-NR hubs. The Everest powers the Grandioso P1/P1PSU and a Cybershaft clock. The rest of the system (amps, preamp, HDPlex LPSU, Wavelet v2 and Valor speakers are powered through a separate Typhon T30. It would be a great test to run,...wouldn't need to turn off amps, preamp or speaker plane. The second phase of the test could then be swapping the Everest back in to reacclimatize system, hearing, etc. and then a day or so later swapping the Everest-X for the Typhon T30.
If would be a great test....closest to a good A:B I can think of . The Everest-X could then be taken across town to a friend's system and stood up right next to an Everest powering a Taiko Olympus, MSB 3box stack, Pilium amp+preamp and Alsyvoxx system (and a hell of a vinyl front-end too) if that friend were amenable. Two entirely different systems, 3 test scenarios. Happy to do it and write up detailed results over a week or two period if an Everest-X were to find its way to town. I can also easily swap in Altaira-X for any or all of 3 Altaira hubs here.
