I must give Walnut the thumbs up on the Isoclean. I waded my way through a myriad of "conditioners". Even the newer Thor, Hydra, and Sound App Ref. was a disappointment. Then I heard the Isoclean 80A3. I purchased it with the Focus PC and it wow'ed me so much I also purchased the transformer set that is suggested for an add-on. It has been the greatest improvement to my system I can say I ever made. It took my measly 60K system to a new level. I suggest everyone in the quagmyer of conditioning goo to check it out.
