Don't know if this is allowed but I wanted to tell my VSA friends about my offering on Trading Post here of what I found is a great front end with VR4SR, then VR5 Anni, and now VR55. Original Owner Ayon CD5s - combines excellent transport and all digital format ready DAC with top level Class A tubed preamp with analogue volume control. VSA speakers love tubes and I personally found it is more like real music, than the top line units of other manufacturers. All new tubes and just given perfect bill of health of USA Tube Audio. I am trading up in the same line to keep the same sound which I love, and the simplicity of the one box design. PM for details.
