Long XLR Cable Length From Phono Stage to Line Stage

[Audiophilehi]

Is anybody using a long XLR interconnect (5M-7M) from the Phono Stage to the Line Stage? With new construction starting with my new listening room I’ll be rearranging things a bit.

I’m assuming it should be OK with the balanced XLR interconnect as opposed to the RCA interconnect.

Long line level XLR balanced interconnects are in the range of about 100 meters (300 feet) or much longer.
5 or 7 meter XLR interconnects are short XLR interconnects indeed.
Now for seldom seen, phono cartridge out to pre-amp in, it's a different ballgame.

The application would not be from phono Cartridge to preamp. There would be a 1 meter RCA interconnect from cartridge to phono stage and from phono stage to preamp would be. 5-7 meter XLR interconnect.

For interconnects much longer than 3 meters (10 feet) a complete balanced XLR interconnect systems is most often better than an RCA interconnect system.

that is completely false.

I agree with XV-1. provided the input impedance of the line stage is 10x greater than the output impedance of the phono stage you wont have freq roll off at the extremes, I actually like to see 20x to be totally safe. Furthermore, low capacitance ICs are preferred when running single-ended, I've run up to 30 ft of single-ended ICs without deleterious effects.

that is completely false.

completely false ?? tell us why !!

For both long and short runs I use balanced if at all possible, because with so much gear and external EMI I can only run single-ended connections for a short length before they will pick up noise.

even with shielded SE connections? thanks!

Yep, but it depends on the design of the Single Ended RCA output stage, interconnect cable, input stage and AC mains wiring system.
It's called 'Common Impedance Coupling Noise' current.
