Long cables from turntable or phono stage
Db, Here is the link to the Mogami spec sheet: http://www.mogamicable.com/category/bulk/microphone/quality_balanced/ I bought my cable online at Redco Audio in CT |

A phono stage input capacitance of 200 pf would make it impossible to optimally match nearly all of those cartridges, the possible exceptions being those in the 250 to 300 pf area when used with short lengths of low capacitance cables. How did you obtain that information? Best regards, -- Al |
DB, after checking further I found the following quotes from John Curl, the very distinguished designer who as you are undoubtedly aware did the electrical design of the JC-3. The quotes appear on pages 3953 and 3956 of this thread: There is a 100pf cap at the input to ground for the JC-3. Some criticism has made me now wonder if 50 pf might be better?Best regards, -- Al |
Thanks for the link, Nick. I'm going to try a pair of the 2549 Mogami cables. Al, it appears as though there may be a capacitance mismatch, so I may need to add capacitance using the device you suggested after I install the Mogami cables. I'll do some careful listening first. The sound is superb with the AQ cables I'm currently using, with no HF roll-off or thinning. There is a low level sizzle that I can hear if I put ear close to the HF driver, but not audible to me at my listening position. I hope shorter cables carefully routed will end that sizzle. I think the 2549s are designed to resist such interference. db |
