Did you merely rewash your records you had already cleaned with Disc Doctor? Or did you get 2 equivalently dirty, uncleaned records? Or did you buy 2 brand new copies of the same record and use each system to clean them?If was the first, then did you reclean equivalent records using the Disc Doctor on some and the Walker Audio on the others?

I was going to write a fuller review later on the prelude but a quick answer is I looked thru my 2000+ record collection and found Idenical promo 12" singles that were untreated with idenical matrix numbers. One record in paticular was a steely dan double sided "12" promo single with "Aja" on both sides. I listened to the promos prior to cleaning to make sure they sounded excatally the same and again all records were Untreated prior to being cleaned. I cleaned one side with DD the the other side with Prelude then did a a/b listening on my Basis 2500/Vector 4 combo. I was very carefull to select idenical promos. 99.8% of my record collection was unusable for this test even though I have numerious copies of many of the same records but they all sounded different or were previously cleaned so they could not be used for this evaluation. I really wanted to know if prelude was superior to DD or if I just wasted $90. The difference surprised me as I have been a happy Disc Doctor user for years.
That explanation was helpful and useful too! I may have to try the Prelude system. I hate to buy full strength water over the 'net as you pay alot for full strength water. As it is, I have a sophisticated water treatment system which includes reverse osmosis.Part of the improvement in your results may be the result of using the better water that Walker Audio provides. I assume that you use tap water for the Disc Doctor or are you using fully treated reverse osmosis water? The result of the water treatment I use is water without minerals and chemicals. Using tap water will result in minerals and chemicals (such as chlorine) left in and on your record. Well water may not have the chemicals but it has the minerals.
For the Disc doctor cleaning I used regular distilled water purchased at the grocery store for about $1. The walker Prelude system does use a much higher grade of distilled water that says "Laboratory grade" on the label. Lloyd told me over the phone he manfactures his own distilled water to very high purity standards which is much more expensive and more time consuming than standard distilled water. This is the same water that is used to mix the active enzymes that come in powder form when you purchase the prelude kit. The active enzymes are effective for several hours after you do the water mix so any excess unused material muse be thrown away afterwards.
I'm not a scientist. I suppose it's sufficient. Reverse osmosis treatment (in addition to many other necessary filtration steps) is the most supreme water filtration. This is what is used in hospitals. But for record cleaning? It may be more than necessary. In any event, I probably will try it my next go 'round.
