How long can one go with interconnects to a cart.?


Curious about how far can you get away with in using a quality cable for distance from the phono amp? I have a .45mc Cart. and It might need to be mounted to wall down the way from the system in the near future, Right now its running on a 2.5 foot cable, which is obviously extremely short, and then has probably 12 to 14" of tonearm cable after that feeding the cartridge..

In this config I have ZERO loss or issues, powerful output and rock bottom bass, perfectly vast soundstaging etc... However how far can I go without lossing any power output or details with putting in a much longer interconnect to satisfy the new location distance? I might need something as long as 13 to 20 feet at a point depending how neatly I can tie up stuff running up and down walls.

Before I get all the questions of Why do this? Why not do that? Understand I know every option of placement in the world, thats not the point here, No I don't want to run my amps with 20 ft speaker cables, or 20 ft interconnects, and move the preamps etc.. with the turntable if possible.

Thanks for your experience and suggestions in this matter.

I admit I haven't tried it, but it seems to me that a long interconnect (say 15-20 ft) might be OK. The current from the cartridge is tiny, so resistance is not an issue. Capacitance might be, depending on what the cartridge wants, and hum might occur if you can't physically isolate the wire. Try some inexpensive very low capacitance coax, and see what you get. I doubt that many audiophiles have actually used such a long interconnect because it is generally convenient to have the preamp close at hand when playing LPs.
Audiofeil...
"lengths of 10'or 20' as suggested *CAN* cause severe degradation of the signal". Did you ever actually try it?

I am a believer in short cables for speakers, but in that case there is a lot of current flowing. Of course I personally have short phono cables, but it would not surprise me at all if long ones were fine.
Audiofeil...Rwwear says he tried it, so I would trust his opinion over that of a "high end cable manufacturer". Those guys are more famous for black magic than for "solid scientific principles". Could you tell us what those principles are? I agree that my 40+ years of electronic engineering work don't prove anything, but you seem to value such when cited by a wiremonger.
