I preferred no power conditioner on my Spectron. I previously owned a Hydra and then an Audio Magic Stealth. I kept the Spectron directly to the dedicated line (JPS labs in-wall cable with a FIM outlet). I have since been fortunate to greatly upgrade my electronics and cables. My speakers have been the same Silverline LaFolias. I now use no power conditioner. With my upgrades, my system sounds BY FAR the best it ever has. IMO, conditioners may be right in some applications, I have found that a simplier system, using higher quality components and cables, has brought me much closer to musical happiness. Good luck.
