@sns "Without switch, images and sound stage wonderfully dimensional and life sized. With added switch, while there was a minute increase in lowest level information, image outlines were drawn too precisely, still three dimensional but with cookie cutter edges, not lifelike at all."
Switches have their own sound signature that probably takes the listener time to adjust to.
The big advantage of adding an etherstream2 for me was the reduction in harshness. I have compared it to other much more expensive switches and I think most of these high end switches are way overpriced.
