Phono cables/philosphy ?


I have balanced phono cables of 1 meter (Nordost Baldur) I purposely went for the simpler design (fewer strands) because the more expensive ones in the line just seem to use more strands of the same stuff. Brands aside, do you think a simpler (less wire) cable makes more sense because of the low power of the signal? i have seen hair-like phono cables and fat ones and have wondered if driving so much metal makes sense (physically). Since I have xlr to xlr I never found any stock phono cables that would work and only considered regular interconnects. I guess I could special order some. Do most of you running xlr to xlr use regular interconnects? Thanks

From a technical standpoint, I don't think that the gauge of the conductors will make any difference in itself.

The most important factor is probably the capacitance of the particular cable. If you are using a low output moving coil cartridge, in general the lower the capacitance the better. See the post by Lyra cartridge designer JCarr dated 8-14-10 in this thread. At 20 pf/ft, the capacitance of your Baldur cables is reasonably low. Keep in mind that the total capacitance of the cable is proportional to length.

If you are using a moving magnet cartridge, then the cable capacitance + the input capacitance of the phono stage + the capacitance of the wiring in the turntable and tonearm should fall within the range that is hopefully specified by the cartridge manufacturer.

Shield quality is also important for low level phono signals, of course. The single 97% braided shield of the Baldur is reasonably good, but not as good as a configuration such as a double-shield that provides 100% coverage. The difference may not be significant, though, especially given the noise rejection provided by the balanced connection.

Beyond those factors, it becomes a matter of experimentation to see what sounds best in your particular setup, IMO.

I found a paper online awhile back that puts all this into easily understood terms. The good part is that it explains series inductance and skin effect in a way that anyone can follow. It is somewhat of a primer to understanding how wire works.

Here's the link. Bear in mind that it is a .pdf download, although a small one.
