I no longer use line conditioners of any type. I found that conditioners cast their signature over the entire system - even into components which do not benefit from the conditioner. Upon extensive auditioning with various power cords and conditioners, I found that the conditioners only really benefited digital components. It seemed silly having one component plugged into a conditioner - given that the conditioners had multiple outlets.
For me, the best results were obtained by using various power cords - specifically chosen for each component - plugged into dedicated outlets. This allowed me to tune the system with far better results - and greater precision -than by simply using a power conditioner.
The Supratek signature can be tuned with either device (conditioners or cords) however in my system I haven't been able to find a robust cord which ads improvement without a negative side effect. For example, if my system has any more bass, it would be more than what seems accurate or appropriate. Many of the PC's I've tried on the Supratek have increased the "slam" of the bass dramatically and I find this puts the bass out of proportion with the rest of the music.
There is a point when a system becomes very difficult to balance... adding positive influence without taking or distracting.
Currently, I use a Bybee pro power cord with my Supratek because I found it to have little or no side effects.
