Just as an update and not my final say on the Blue Circle PLC Thingee I'd like to state that I really, really like what I'm hearing. Everything I have ( Marantz PM-15S2b and 15S2b SACD player, OPPO blu ray player, NAD tuner, Samsung Plasma TV and TWC cable box) are plugged into it and it all sounds rather fine, even better than before.
I know it's considered verbotten to put everything on just one outlet but so far there are no downsides I can hear. However the capacitors in the Thingee cleans things up is beyond me but the results are a cleaner presentation, deeper soundstage (due to the notes having that super clean aspect), and overall more revealing presentation. There's a track on Quadro Nuevo's Mocca Flor titled Sultana where a small metal drum marks time for most of the piece (left of center, towards the back). What I never heard was how much earlier it starts to mark time, how softly it begins. :-)---big time.
The most interesting thing is that I now have to attenuate the volume a full 3db as my previous setting is now much too loud for my tastes. I don't need the extra volume as I'm hearing so much more along with the greater dynamics that are coming through. This is making me wonder if I shouldn't have ordered that 10 AWG Cullen Red Copper PC as the TTG 14AWG PC seems to be doing the trick.
I can't draw any conclusions on the TV picture until I plop in "Mud" tonight and will post again with what I see. That, and after what Al mentioned, I have more permutations to go through. After a few days of leaving it at is, I'll have the new PC to try and then piggyback the BrickWall as well. Nothing like having to pick and choose which better setup to use. :-)
All the best,
Nonoise
