This was my review of the Quantum AC, a parallel filter which contains caps and bybee filters:
http://www.audiocircle.com/index.php?topic=68664.0Great stuff. So what changed? Power delivery to my home. The filter does indeed require five weeks to settle in the first time you plug it in and after a blackout. This summer, after three blackouts I finally, well, pulled the plug.
For those is areas with more dependable power, this filter is wonderful, especially with digital sources. The Quantum was the predecessor of the mighty Studio AC.
Happy listening,
Phil
Simply plug into the lower receptacle of a duplex. While full settle in takes five weeks, your system will sound appreciably better after about three.
