My speakers are analog (JM Lab Electra powered by Bryston 9B-SST). I had heard that the balanced output G68 was much closer to the 861 than the single ended versions, but I don't know what DACs are used in either. You mentioned upgrades from Meridian for the v4. Where would I find a list of these upgrades?
