I have the SP 100s and use Cardas GR. I tried the Anti Cables, they leave out a lot of the music; sold them for half what I paid. If you want a cheaper one Mapleshade is good with a similar bias toward the top end as the A-Cs but more acceptable. It may be that the warmth is coming from the amp, not the cable; if you can try another amp, possibly a good SS, on the speakers to see if this is the case. There are two different ways to go with cables; looking for maximum accuracy and using them as tone controls. I find the Cardas accurate with my Spendors and Gamut L5s. One friend uses Sasha with Lamm hybrids, and another uses AvauntGuard [sp.?] Horns with custom tube amps and both use GRs. BUT if you want your system to sound more forward or brighter they are not the best choice. I would look at Transparent in that case. The lower ranges, I saw an older series Ultra for around $400 that I though about buying for my HT myself.
