Can anyone comment on the performance of the Bolder ICE digital cables with Bybee slipstream purifiers (silver or copper) compared to similarly priced offerings from Audioquest (VSM-5 and Hawk Eye)? Please note that both Audioquest cables feature pure silver conductors. The only obvious difference between the VSM-5 and the Hawk Eye is Audioquest's mystical DBS system.
My current system is as follows:
Quad 12L monitors
Quad L Series subwoofer
Panasonic SA-XR45 (Bolder HT mods)
Denon DVD-1920 (Underwood mods)
Shunyata Research Hydra 4 PLC
Signal Cable digital and power cables
ASC TubeTraps - two 16x48 traps
ASC custom monitor stands
Great room (large with vaulted ceilings)
My goal is to maximize the performance of my beloved Bolder Panasonic SA-XR45, which is about the greatest "invention" in audio I've come across (way to go, Wayne). My current system sounds extremely smooth and resolved to my ears, so I really just want more of the same.

Thanks.
