Solid core phono interconnect - Recommend Please


Hi,
I am looking for a high quality phono interconnect (RCA-RCA) preferably solid core. Currently I use ASI Liveline which is very detailed and transparent but it is not very fluid. The only reason I am looking for a solid core is because I find them more transparent than typical multi-strand cables. A good solid core copper interconnect should get me the flow and transparency I guess. Kindly recommend some. It need not be shielded because I dont live in the city area. It should be neutral, fluid and dynamic.

I would not gamble on an unshielded phono cable, especially when used in conjunction with a low output cartridge such as yours. Regardless of the nature of the area in which you live, there are a lot of potential sources of radiated high frequency interference within the home, that could have audible consequences. Including appliances cycling on and off, some kinds of lighting, and all sorts of electronics perhaps including the audio system itself.

Also, I see that your phono stage provides some rather unusual capacitive loading options, namely 1000 pf, 4700 pf, and 10000 pf in addition to the much more conventional 100 pf. I don't know what the intended purpose of the three unusually high capacitance values may be, but I'm guessing that the designers might have had particular concerns about the possibility of radio frequency interference (RFI) entering the phono stage and affecting its sonics (high input capacitance would provide a filtering effect at RF frequencies, to some degree).

In general, it is sonically preferable to minimize capacitive loading of an LOMC cartridge. In this case that would mean using the 100 pf choice provided by your phono stage. Using an unshielded cable might make that choice unsuitable.

I have no specific cable suggestions meeting your other criteria, but I thought I would offer those comments.

Good luck. Regards,

Shielding can raise the capacitance, which can decrease bandwidth and therefore speed (resolution) somewhat, but it also depends on the implementation.... You probably want to keep this cable's total capacitance at 100 pF or lower.
I agree. I'll add that in addition to the design of the particular cable it also depends on the application. The effects and significance of cable capacitance will be very different in a LOMC phono application than in an application involving a high output MM cartridge, or in a line-level analog application. In the case of cables used between LOMC cartridges and phono stages, the significance of keeping cable capacitance low is explained by Lyra cartridge designer Jonathan Carr in his post dated 8-14-10 here. Basically, keeping cable capacitance low works in the direction of allowing lighter (higher value) resistive loading, while at the same time minimizing or avoiding adverse effects on phono stage sonics that might otherwise be a consequence of the lighter loading. The lighter loading in turn "will benefit dynamic range, resolution and transient impact."

I couldn't find any technical info on your Van den Hul cable. I would consider the Mogami to be medium capacitance, at around 26 pf/ft. While humble and inexpensive Blue Jeans LC-1, which is shielded, achieves 12.2 pf/ft, approximately the same value as one of the low capacitance cables Jonathan indicated in his post "resulted [for a 1.2 meter length] in greater flexibility in loading, a more natural tonal balance with better dynamics and resolution, and were a worthwhile upgrade." Which of course is not to say that there aren't other sonically significant differences between Blue Jeans and his or other low capacitance phono cables.

Good luck. Regards,
