Audio Desk Record Cleaner

Isochronism, yes, it is filtered, it is the filtering process that is important. When I was a grad student we made our own lab water with a very nice filter system. Started out with tap water. Could be toilet water for that matter as long as one filters it properly.

Look at the solids ppm content of aquafina. It is perfectly appropriate for this application. You will be inducing more filth onto your record as it passes through the air from the cleaner to the sleeve. I thought about using some audiophile approved reagent water and then I did the math...someday I may try it just for kicks.

Rfogel8 if the transducers are defective and the record was cleaned with just the rollers, I'm sure the record would look just as clean. Like I said usually with ultrasonic cleaners you can see some sort of bubble action.

Aquafina? A 5gal box of Nerl Reagent Grade is only $40. Seems odd to spend thousands on a record cleaner then bail on water.

Had I known I could have purchased 5G for $40 (and it's on sale!!) I probably would have although it is still, IMO, completely unnecessary. How much purer can it possibly be than 4ppm? 2? 1ppm? I guarantee the filter in this unit will not get you even remotely close to this figure after one record wash. How much junk is embedded into the grooves after the drying cycle? There is a thin screen over the fan that cannot possibly filter the air very well. The more I think about it, the better I feel about that extra $37 in my pocket or record collection. The AD works great. Is it perfect? No.
