Hi, I have compared both. Each has different strengths and weaknesses. For me, the CX are more extended up top and fairly even and the VX lower background hash. In my main system I ended up with a Python CX on my Genesis Digital Lens and a Python VX on my Slimdevices Transporter giving me the best balance. I would try to compare both side-by-side if you can since I don't see a clear winner.
