Thanks again guys. For now, things seem to sound good with Purist Aqueous Anniversary (1M)from source to preamp, and Purist Venustas (3M) from pre to my Cary 500MB monos. I have been trying different speaker cables after selling my Venustas bi-wires. I was able to purchase a pair of Purist Aqueous Anniversary true bi-wires. The Aqueous Anniversary line uses copper and gold conductors, while the Venustas line uses silver, copper and gold conductors. The silver in the Venustas speaker cables sort of tipped things up in my system, so the Aqueous cables improved tonality in the direction I wanted to go. I also purchased some Harmonic Technology speaker cables, and I am using a pair of the Pro9 Plus from my amps to the LF posts on my Aerial 9's and a new pair of Pro 9 Reference from my amps to the MF/HF posts. I am fortunate the amps have dual speaker terminals for bi-wiring two separate runs of cables. Both the HT cables are 5 feet long, and for now the bass using the HT cables is outstanding, and the mids are full and rich. My initial impression is that both speaker cables are good, but the HT have better bass while the Purist Aqueous may be a bit "quieter." In a week or two I will put the Aqueous back in and see how I like them. I would still be interested in some copper IC's from preamp to amps, but I need 3M, so I will probably hang out until I see a good deal on something, or... I may stay with the Venustas since the silver in the IC's does not seem to bother me like it did with the speaker cables.
