I may opt to try some blue jeans specified cables
interesting article from Blue Jeans Cables...
Conclusions:
Our conclusion is that for rejection of low-frequency, high-energy noise, just as electrical theory would suggest, a coaxial cable with a highly-conductive double braid shield will outperform similar braid/foil and single braid cables. When we recently had our own unbalanced audio cable, BJC LC-1, custom-built by Belden, we went with the same shield configuration found on the best performer of these: Canare LV-77S, but with a softer texture for better flexibility and lower capacitance for less high-frequency rolloff. This new cable replaces our prior recommendation of LV-77S for subwoofer use and Belden 1505F for general audio use.
Does this mean, then, that a double-braid cable will always be the best choice from a noise rejection standpoint? Not necessarily. First, for video and RF applications, where RFI is an important consideration, the 100% coverage offered by a good foil/braid combination (e.g., Belden 1694A) will outperform a braid-only shield. Second, it's possible, in an RF-noisy environment (for example, a home close to radio and TV broadcast antennas), for RF to play a role in audio quality as well. Strong RF signals can enter audio circuits and be "rectified," stripping their high-frequency content and causing audible interference. In such a situation, a braid/foil shield may well provide the more effective shield; but for most users, in most environments, EMI is a far more likely cause of audio mischief than RFI, and the highly conductive double braid will reduce this low-frequency noise more effectively.
