Anti-cables VS. River Cable/cable lengths


Looking for some feedback regarding how these cables compare and any suggestions for other low-cost cables to consider. System: Creek 5350 se classic, Rotel 1072 player, B&W 703's. I have fairly long runs: 15 and 27 feet and am wondering how important it is to use the same length of cable for each run???

Thanks!

Somec59, I hate overly bright sound! My amp is quite "warm' for a s. state, however, and I could do with a bit more clarity. What are you using for amplification?
I tried the following amps: Adcom, Rotel, PS Audio, Yamaha and I settled on a 20 year old and mellow 75 watt Onkyo with a tube pre and Shaninian speakers
Stuartk, I am not a big cable-swapper, so I can't cite a litany of cable comparisons for you. However, if you check out my virtual systems and my other posts here, you will see that I listen to a lot of acoustic music and prize transparency and timbral accuracy. The Morrow cables will give you that. They compare very favorably with the Jena Labs cables, which are another very well balanced and natural sounding cable.
I performed several extended cable auditions, and ended up with Audio Art cables all around - very musical and balanced, compared to the Anti-Cables which I found overly spotlit the highs, shortened depth, and ultimately became fatiguing. YMMV, of course, as i find cables are very system dependent. But these have served me well - they have stayed even as my system has progressed. Website is www.audioart.com with which I am NOT affiliated; I just enjoy their cables!
Thanks for your suggestions. I need long (30 foot) runs and audioart only lists up to 12 foot runs on their site, Slaw3. Cincy_bob, I have contacted Morrow about the question of long runs, am waiting for a response. I also spoke with Paul at Clear Day (what a nice guy!) and he had concerns about such long runs, but unfortunately, I'm stuck with 'em. Mapleshade advertises cable they say is specifically designed for long runs, so I may try that, too.
