I just bought a Belkin Pure AV PF 30 today and plugged the following into it:
Rotel RSX 1055
Rotel RDV 1060
DVDO iScan HD
Panasonic HDTV Plasma
Xbox 360.
The reason i bought it was for surge protection, and this model looks really good especially in my B&O av rack. I hate to say it, and would never believe it if someone else said this, but it has actually improved my sound and video quality. I figured that if I bought a Richard Grey unit I may hear/see something different for better or worse, but dont have the budget for that yet. I DO notice something different in my system with the Belkin. I know may of you think that cant be possible and depending on your original power source it may be more noticable to some then others, but its there.
for $300 CDN APX I highly recomend it.
