Compromise is right. The cleanest records I know are the Hot Stampers from Better-Records.com they are cleaned using the Walker Enzyme 4 step method on a very expensive RCM that uses a cleaning wand that continually feeds fresh cleaning thread so all dirt is continually lifted off the record. This eliminates the major problem with all other RCM designs which is that the cleaning brush is always building up crud, ultimately smearing it all over the supposedly clean records.
Granted the crud we are talking about is not visible. But totally invisible crud does make a difference! My records scrubbed with Disc Doctor looked really clean. Same records after same cleaning process only with Walker Enzyme sound better. Not night and day, but definitely better. Not necessarily more quiet, but more fine detail.
The downside is the VPI RCM is only used to suck off the final rinses. Because otherwise, crud smear. So a very laborious process, a good 3 min per record, almost all hand labor.
But, I didn't have to spend $4k on the fancy RCM. Compromise.
