I have built a second system that I seem to be spending more time with. Much simpler and cost effective, but in a much larger room that presents everything in better scale. My McIntosh rig is in a highly treated but very small (15'6" x 10' 6") room and although it is very good....the room is highly restrictive simply due to size. I plan to replace the MC75's with a single MC275, replace the two box C500T with a C2700 single box, run a smaller REL with Harbeth P3esr speakers. Looking for cabling suggestions....something with the openess and focus of Synergistic Research without all the grounding wires. Possible it may end up being the SR lower level cables that don't require grounding but was looking for suggestions. I am running Harbeth Compact 7's in the larger room and expect to move up to Super HL5+ or 40.2's. I really like the Harbeths, not quite as refined as the SF's but IMO, tonally superior. They are both very good at imaging.
going from audiophile grade cables to generic or pro-grade cables will help to downsize and cut cost without compromising the rest of quality.
Mogami is for interconnect cables and Canary is for speaker wire can be found in most of pro-gear retailers such as fullcompas.com, musiciansfriend.com, zzounds.com, bhphotovideo.com
I decided to switch to Video Component Cables, two gave me 3 pairs of interconnects, each pair different colored connectors. (they peel apart to 3 individual cables easily).
6 nines copper, superior insulation, and, aside from the price, what makes me happiest, very tight locking RCA connectors.
Dynamic Designs. The battery pack powered shielding is easy, batteries last a year if left on. Titania series power cords check all the boxes you describe. The more DD you use, the more holographic it gets. Nuanced and natural sounding with detail, extension, etcetcetc. I use a Heritage AE15 set of IC's, too.
