Long cables from turntable or phono stage


Hi I have a question that involves a compromise. I have a turntable that (for various reasons) has to be positioned a little distance from the hifi, about 4m of cable. Would it be better to connect the turntable (transcriptors hydraulic reference, ADC XLM ii) to the phono stage (moon 110LP) then run long singled ended cable to the amplifier or should I run long extension cable from the turntable to the phono stage and use a short interconnect from the phono stage to the amplifier? For visual reasons the latter is better. Any thoughts?
(Amp is plinius tautoro/SA103, speakers confidence C1 Dynaudio, tautoro is the line stage only version).

connect turntable to phonostage with 1m long IC cable regardless weather you're using balanced or unbalanced arm wires. that's how all of the sound pickups designed to synergise with the cartridge inductive load and best pickup performance. per-meter active resistance of tonearm wire does a trick of increasing detail performance of cartridge. length of phono to preamp cable is less of importance, but shorter ones may give more benefits depending on your rest of equipment. tru differentially balanced stages pretty much don't care of the output wire length at all.
OK- I am going to be the lone voice here. Most LOMC cartridge don't make much voltage but they do make a surprising amount of current, otherwise you could not load them at 50 or 100 ohms and get away with it.

So I am asking here that you all think about that simple fact.

What this means is that the cartridge and cable is a fairly low impedance system, and the length of the cable is thus not nearly as problematic as suggested above. What the real problem is: the cartridge has an inductance and the cable has a capacitance. This will not cause problems at audio frequencies, but will cause issues at Radio Frequencies.

This is true even if the cable is only one meter BTW.

So what you **may** have to do is adjust the loading resistor, should it be the case that your preamp cares about RF coming into its phono input (some preamps, particularly solid state preamps, don't like RF at their inputs and this can really affect the sound).

Bottom line: you can very successfully run a 4 meter interconnect. You may experience some artifact from the cable, but if you run it balanced you can eliminate that.

Now if you are using a high output moving magnet, then its a different deal and you will find that because its impedance is higher, it is also more sensitive to the cable.
Ralph(Atamsphere) What is meant by
if you run it balanced
aren't all phono cables RCA unbalanced?
Ralph,

The OP is not using a LOMC. His ADC XLM is a MM cartridge, so the last sentence of your post is the only one applicable to *him*.

That said, those of us who use LOMCs appreciate your knowledgeable input, as always.
Nick, No. The vast majority of cartridges are inherently balanced output. So it is possible to use a true balanced connection from the cartridge to the phono input. It especially makes sense to do so if you have a truly balanced phono stage. Such products are still rather rare, but they do exist. Atma-sphere preamplifiers, MP1 and MP3, are examples of such. The connection from the cartridge requires three discrete wires (positive and negative "hot" wires derived from what are labeled "hot and ground" on the cartridge body, and a separate ground) into an XLR connector, rather than the two normally associated with RCA connection ("hot" and "ground", as per the color-coded labels on the cartridge body).
