I got a chance to demo the cables I mentioned earlier in this post and was very impressed. This is the best cable line that I have heard so far and I've heard quite a few. I must admit though, that I did not feel that the mini power couplers helped the sound. In fact, I think they may have made it worse. I must say that they were plugged into a surge protector due to a shortage of outlets so this may have impacted the quality. I would also like to mention that there was a large difference betweeen the Designers' and Absolute Reference digital interconnects. The soundstage was much larger with the Absolute and everything that I felt was missing at the bottom and top end of the Designers' Reference came back. Is the Absolute almost twice as good as the Designers'? That's up to the individual I suppose, but on my system it is worth the extra cash.
There truly is a synergy that is created by using all Synergistic cables. With just the interconnects and digital cables, I felt some bass, air, and high end were missing. When my Alpha-Core MI2 speaker cables were replaced with the Resolution Reference, all these problems disappeared. Regardless, if you are in the market for a high-end cable, these are definitely worth auditioning.
