Hi, I see you have the SR Qauttro to power the SR cables.
I use the Galileo MPC's (housed in a Vibex Rhodium Powerblock )and found out that they have a huge influence
on the sound depending the underground/tuningfeet used.
It is worth a try to place your Quattro on proper tuningfeet/spikes or rack.
You will not believe what you hear.
BTW thx for the post on the Speaker Cells.
Joris.
