long RCA cables . . .where?

Long cable from MC amp to preamp.

could the signal be deteriorated in some form with 20ft of cable?

quite possibly.

Long cables from the MC preamp to other preamp. There is no other choice.

Thanks for your input.
Any more ideas about any significance lost in signal quality with this long run?. Thx.

Is the mc amp a phono stage, which provides riaa equalization and a line level output? Or is it just a step-up, which outputs a moving-magnet phono type of level?

I would not want to run a phono-level signal through 20 feet of cable either before or after the mc amp. If the mc amp outputs a line-level signal, you may get away with it, provided that:

-- the output impedance of the mc amp is low.
-- the cable capacitance is low.
-- the shielding in the cable is high quality.

The only conclusive way to tell is to try it, of course.

AL,
Thanks for your reply. The mc amp outputs a line-level signal. As you said, I have to try it to know for sure.

It will depend on the quality of the MC preamp. The lower the capacitance of your RCA cables the better.

Dear Jorsan: None, 20' are a lot for that kind of signal.

regards and enjoy the music.

I had to run some very long interconnects as well and ended up using the Harmonic Technology Photon interconnects. They work great due to their technology for long runs without any loss of signal or rfi issues. They are costly though so it depends on what your budget is.

What's your current phono stage? Unless this would be a big step down, you might consider getting a PS Audio GCPH phono preamp. with its variable gain, it should have no trouble amplifying an LOMC signal and driving a long interconnect, especially if it's low in capacitance (Kimber, Harmonic Technology).

Thanks again. My phono preamp is a Heed Quasar.
