Speaker Cable for Tube SET System?


I would like some (tried and true) recommendations for speaker cable. My concern other than overall sound is bass control (damping and what effects it, if this is a part of the wire puzzle). The system is: Audion Silver Night 300B stereo version (7.5 watts), Reynaud Twin speakers, CAL Icon MKII with Bel Canto DAC, Mapleshade Digital IC, Homegrown Super Silver analog IC, BMI Whale PC's and two Monster HTS2000 power conditioners. The only two cables that I am considering at this time are: the Mapleshade Single or Double Helix and Analysis Plus Oval 12. I can get by with 10 ft runs, but would prefer to have 12 footers to cover any future reconfigurations (or to use them in a second system as time goes by) and would like to keep the cost at $300 and under. I am currently using Kimber 4VS and would like a more natural sound than they seem to offer in this setup, plus bass control as mentioned before. I will probably only audition two to three cables at the most and or buy and then sell used if I hear no improvement. Thanks.

Hi Guys! Anyone tried the Monster Sigma Retro Gold speaker cables and Interconnect? I heard they are very good cables. As a friend of mine was all raves about it. He is running SETs too. My set up is: Sonus Faber Grand pianos, Cary CAD 300B Signatures Monoblocks (latest 15 watts version with Western Electric 300Bs. New, less than 50 hours of playing time) upgraded Wadia 2000 with digital volume control and Wadia WT 2000 transport. I now have MIT T2 Bi-wire and Tara Labs Master Generation II as interconnects. I'm planning to upgrade all my cables. My budget is around $1,500.00 used.
Riv3r: I have no experience with the Monster cables, but will suggest that you take a look at the OTA thread (search under OTA at the bottom of the first page of the forums). This is what I am now using and I have no desire to try other cables. It is that good.
I just heard Nordost Valhalla as the link between a BAT VK75 SE and Avantgarde trios, Oh My. Where did my socks go?
