I had been waiting for weeks for these ultimate outlets to do some magic to my amps (Bryston 7b-st) like the 300 had done for my SA-1 and Tact Rsc 2.o. I had similar good experience with the ultimate power cord which was purchased to go with the 300 but I found the most emprovemnt with it attached to my SA-1. Now enter the Untimate outlets. I bought one for each of the amps. I set my system to mono and did double blind testing on each speaker. the outlet did have a significant effect on the sound in my system. all negative. it was likd i had put a blanket over the speaker it was hooked into. I tried one on one speaker; then the next (not knowing which one was connected until the music played). I couldnt stand it. after 2 days of burn in i boxd them up. they were that bad in my system. hopefully this was an abaration system specific or an early defective run. YMMV. I would sure like to know what they tested these on and whether the results were mixed. p.s. Audio is a great company. I sure hate to see them make a product which is not only mediocre, but substantially degrades the sound.
Sorry, but feeling obligated, to report this news.
