Following this tread with great interest, so please share whether the initial brightness of the Ultimate version subsides over time. Thanks.
I'm using a modest IFI Groundhog on an Aqvox switch that connects a modem, (2) routers, and server. I bought the $50 device as a "test" before spending serious money on an Entreq, Synergistic Research, or something similar. Once connected the modem, the Groundhog made a major improvement in SQ. In the quest for better sound, I'll probably replace it with either the Perfect or Ultimate ground cables soon and report back.
