Walker prelude vs. Audio Intelligent

Agree with Stiltskin. AIVS and MoFi's enzyme based fluid systems go far beyond DD. Waiting until you run out of DD is just wasting precious music listening time. Use the DD to wash the car or something.

I haven't compared Walker's fluids, but since the theory is similar I'd expect similar results.

Sorry, I haven't done a head to head comparison of the current AIVS to the Walker Audio Prelude that I use. As Stiltskin and Doug say, both products work well.

Walker Audio offers a full satisfaction guarantee, return the unused portion and they will refund your purchase price (not shipping). AIVS used to offer a sample trial kit of the fluids, they may do still.

Whichever fluid you use, upgrade your VPI 17F with the replacement vacuum wand now being offered by Walker Audio (recent thread here).

I just decided to move up as well and ordered the Walker products. Should get them today. Can't wait!

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,

Steam beats them both. But I do like using the AI cleaners and pure water rinse. I must admit that all of the positive comments about the Walker solutions makes me a little curious. But then I hear that the Walker rinse has something else in it. Anyone know what that something else is and does it get left behind?
