The Rx thread has been a little quiet. I have recently purchased the Campfire Audio Vega and am learning just how good the Rx really is. When I listen to the Vega on the X3ii alone it is very good, but when I rig it up to the Rx the real magic comes out and am amazed at the experience once can have with an audio package as small as this. What the Rx allows sources to do is simply amazing and I can't recommend this amp more. Very happy to own Campfire Audio Gear and am very happy with the quality and what it brings and the experience their equipment provides. These really are TOTL products including this Rx Amp.
