Hi, I've got one. It's been kept in a drawer for several years-even after a professionally installed full DADA upgrade (https://dadaelectronics.com.au/doc/A...anual-V1.4.pdf). I used it with a Schiit preamp (very good). Now have a Sugden with the Quad in reserve ('just in case" -but the Suggie is rock-solid). No idea what it's worth. I live @ S104LN if you want to listen/collect it. R
