Any interest in reviewing a RDL AV-HK1 unbalanced stereo isolation transformer?
I bought one to address a ground loop issue with a USB turntalble - if I connected both the analog and the USB outputs there was persistent high frequency hash. This solved it neatly, although I suppose I could have used a USB ground lift instead (they're a bit cheaper).
Transformers are kinda boring audio-wise, and I'd expect that it measures reasonably well, but I haven't seen much discussion or reviews of transformers here.
Anyway, I can live without this for a few months since I don't really need to connect both outputs simultaneously.
