I own the PS LANRover
My chain is;
Bryston BDP-2>Intona>PS LANRover>Intona>Recovery> Mutec>Mutec> PS Audio Direct Stream.
The LanRover on its own was just ok, but when added into my USB chain it makes a great sound even better.
I must add that I have a linear power supply on the LANRover and Recovery devices. All USB cables are the Curious cables.
