Sd: I bet that is a pretty nice sounding system i.e. Ayre electronics feeding Goertz speaker cabling into Vandy's. I could see how that might impress as it sounds like a nice combo of equipment. Too bad Sammie isn't looking for speaker cables : )
Sammie: Given the fact that you need longer interconnects, you may want to start looking at capacitance figures. Running a high capacitance interconnect can tend to mute the treble response of a system, let alone if one has to run a much longer interconnect. The increased length compounds the effect of the high capacitance, elevating the potential for even more softening.
With a longer cable, the geometry of the conductors and / or shielding also comes into play. The added length of low signal level cabling makes it easier for RFI and / or EMI to influence the system. Only problem is, wire geometries and shielding that tend to keep RFI / EMI out of the system tend to raise capacitance, so you are kind of at odds with yourself in that regards. This is yet another reason why shorter interconnects are preferred in an electrical sense.
The use of a twisted pair of conductors can provide both a low capacitance route and a reasonable amount of RFI / EMI rejection at the same time. The use of high grade conducors encapsulated in a small quantity of high grade dielectric may be your best approach here. This approach works pretty well for most any electrical application ( IC's, speaker & AC ), but it may not be optimum for any of those given applications. It is kind of a "universal" approach that should always provide at least "very good" results IF the above criteria are applied. The fact that this is both a relatively easy to achieve geometry and one that is commercially used for other applications can only benefit the end user. This is especially true if one is resourceful in looking for products outside of the "audiophile approved" market. Sean
