Ozzy thanks for your doing this - giving feedback along the way is really helpful - this is what makes the hobby fun and audiogon valuable. fwiw I upgraded my SR basic ground to the SE Ground and it made a nice difference (I couldn't tell a whole lot on the Basic - I may try the new SX ground - will let you know). I am trying the SX powercell with SX cord. When I attach the pigtail from the SX cord to the SE ground, it tightens the stage, enhances focus and transparency, a little more separation. I prefer it, but I wouldn't call it "ground breaking" -HAHA. The tightening of the images may seem to slightly reduce soundstage width, not really sure...but I prefer the little pig tail grounded. I do have other items in my system grounded. But I am using at the moment different speaker cables that don't have the grounding pigtails as they are not SR - I may try SR speaker cables at some point. Interesting side note if you go to the Stealth Cables site and click on technical notes, he posits that the AC power cords' “sound” mostly depend not on the AC carrying wires, but on the ground wire, which NEEDS to be shielded since it's included into the sound SIGNAL PATH (ground path, to be more precise) - that's mostly why different AC power cords sound differently. When you "listen" to a new cable, you are listening in effect to "all" your cables...I think the grounding "scheme" may have more effect than I previously realized....so, that is why I am interested in trying the SR SX ground...perhaps Ted will chime in.
