I have it as well and also recommend the mono version. I have set up an experiment with Miles Davis Kind of Blue working with a local retailer. It involves two copies of the Mobile Fidelity UHQR OneStep LP. One an early release, circa #3400, and the second a later release, circa 20,000. Each has been ultrasonically cleaned by me an equivalent number of times, and listened to on my system. One copy has been submitted for the Perfect Vinyl Forever Archival cleaning process, the second copy awaits comparison to the first. The PVF cleaning should be complete in a week and then a comparison will take place. My intent is to create a new thread detailing the results of the comparison. Obviously I have too much free time, but this should be fun.
