@thyname if it's not broke don't fix it. I am the same with my Innuos Zenith and Statement. Moon 680 and 280D dac's and I am in heaven. Adding a couple of Audiolab DC Blocks to see what these do.
Also have a LessLoss Echo's End on the way for a DEMO with the LessLoss firewalls and footers. More to follow.

Just love EU Audio Gear and NA gear.
