This isn't a perfect comparison, so take it with a grain of salt, but:
I have taken albums cleaned with a VPI machine and AI listened to them, and been happy. Upon visiting a friend, I heard obvious improvement after he cleaned my LPs with Walker's system including step 4, and the same VPI 16.5 that I have.
Even better, after listening he re-cleaned the LP using the new Walker Vortex tube on the VPI and the improvement was startling! Stuff that I can't see is getting removed from the album, because at casual glance, the records were already clean, but you can certainly hear the difference. Remarkable. Cheers,
Spencer
