rsf507,
I tried and ended up buying a Telos Mini Quantum Resonator. Seems like a lot of names..
Anyway, at this time I did not like the effect it had on my main dedicated line. It seemed to make everything more one dimensional and reduced the "air".
I did however find it worked pretty good with my modem/router/etherRegen/After Hours clock/power supply room. This room is away from my main system and on a different circuit. It seemed to add that extra filtering that improved the streaming sound quality.
