Synergistic Research IC Active Shielding


Syn. Res. IC users that have the ICs with the "pigtails", ie set up for active shielding are probably aware of the $1000. box that provides the power for the active shields. Well, SR now has "wall wart" power supplies for a single pair of "pigtail" equipped ICs. I got two of these a couple days ago and like them a lot. SR has an introductory price of $50. apiece ($75. list). Mine came from A Sanctuary of Sound-- a good Audiogon Dealer.

I first plugged these wall warts (they have about 3 ft. leads) into a Monster HTS 1000 power strip, which was plugged into a dedicated outlet-- but forgot to turn the power strip on-- and listened for 3 hours. Duh! These first 3 hours, music sounded too bright, analytic and gave me a headache-- I think there may have been some kind of negative antenna affect going on? And I was wondering if the dealer would take them back?

But when I went to unplug them, I realized that the Mini's were not powered, and the shields not active. After ACTUALLY GIVING THEM POWER, music had a completely different and improved character, whehter compared to the non-powered Minis or compared to my system without them. I don't want to use a lot of Stereophile verbiage here, but I will say music was natural, some edge was gone from what I thought were overly bright CDs, but the most striking improvement was in soundstaging-- stronger and wider, while still sounding natural. The overall improvement was definitely worthwhile, but not dramatic. I sure recommend them. Cheers. Craig.

........I should note that I've only used the Mini's a couple of days, and so don't know if there is a "break-in" factor. I will report back if anything significantly different happens. Craig
Fully agree. Those things took away the 'edge'. I have them 2~3 weeks now. I haven't noticed any break-in effects. I'm told by the dealer that the leads supplied by the 'mini's are different than the original active shielding leads. (According to him) Synergistic will now be using this 'new-and-improved' leads.
Ikarus; thanks for confirming that I wasn't having a "placebo moment". Anyone else out there with experience with either Syn. Res. Active Shield Box or these new "Mini" shield devices. Thanks. Craig.
Craig,
I see you went back to SR cable. I am still using the res. reference with the active sheilding. The word of wisdom is if you ever pick up a used box, make sure it is the new kind with new type of cables. The older type of cable had a bad connectors on them which will get loose and burn the unit. It happened with me and SR guys were too nice and sent me for the free the new type cables with a new module.
good luck.
