Walker prelude vs. Audio Intelligent

I have not tried either cleaner. According to the info in various threads and the products websites, the final rise with AI's last step is pure de-ionized and highly filtered water whereas Walker has a very small amount of alcohol and another ingredient in the 4th step rinse. These ingredients, I surmise, may be left on the vinyl at the end of the cycle. Of course it is possible as well that the alcohol and extra ingredient is not left behind or left behind in such amounts as to not have any impact whatsoever on the vinyl even over the long term. That's why i referenced chemists in my latest query. If you have LLoyd's ear Jtimothya, I'd love to hear the theory as to why the final rinse is something other than pure filtered de-ionized H2O. What's the upside and downside (if any) to additional ingredients?

You are correct with your speculations,

LLoyd Walker has a history of failed and reckless attempts to improve vinyl play back.
Walker's product's are nothing but snake oil.... and his turn table and arm! geez

I confess, LLoyd payed me to hype his product's.

Stick with your Disc Doctor cleaning fluids, they leave nothing behind and have no harmful ingredients

I have a question: is it worth using the full Walker regimen on brand new vinyl? I've been purchasing old sealed vinyl (and brand new pressings as well). I'm just wondering if I'd be wasting these precious fluids on them or whether it's just as applicable.

And do any of you ever use Last preservative?

Has anyone compared steaming with any fluid regimen head to head against either of these two systems alone. Reading a post like this tempts me to try the Walker system but then when I consider the price and the success I'm having with Disc Doctor, Steam and type I reagent grade water I find myself sticking with my less expensive and quicker regimen. Also, is the Walker enzyme mix available separately or does it have to be bought with the rest of the system?

Madfloyd, yes. It is worthwhile using the full Prelude regimen on new high quality vinyl. I demonstrated this with some members of our local audio group during a gathering at my house last weekend. Everyone heard the improvement in clarity and resolution provided by cleaning a couple of new LPs member had brought to play (one was a recent Groove Note pressing, "Percussion Direct," the other a Music Matters Blue Note reissue, "Little Johnny C").

I used the Last Preservative for many years with no adverse effects, but I stopped using it some years ago when I switched to using Disc Doctor and now Prelude cleaning fluids. With really clean vinyl and care in use, I'm not inclined to make the significant investment in the cost of the Last Preservative. I also decided after some comparison listening, that the Last was leaving a slight sonic signature - not as much as the signature left by the original Research Labs fluids, but still audible.
