The Audience Adept Response aR2p-TO High Resolution Power Conditioner is the latest in a product line of well received power conditioners which are priced from $695 to $8,600. The $1,600 aR2p-TO model differs from the basic $695 aR2p in its use of expensive Teflon-dielectric "Aura-T" capacitors with OHNO (mono crystal, oxygen-free) copper leads. I did not experience the basic non-Teflon equipped model.
