24 feet DIN to XLR phono cable for Graham Phantom?

If the preamp accepts the phono signal differentially, then you stand a very good chance of making this work, especially if the cartridge is loaded at something less than 600 ohms.

This will create a low impedance balanced line, and will be quite immune to the cable length. Although the voltage output of the cartridge is quite low, the current is rather robust, else so many LOMC cartridges could not drive 100 ohms or less!

Now its my opinion that if you are placing the turntable in a particular location to minimize vibration, you should consider placing the preamp in the same location for similar reasons. The preamp *should* be able to drive long cables if its balanced (if it can't IMO you need to think about a different preamp- our preamps can drive over 100 feet with ease, like any balanced preamp should). So I would think in most cases that you would not need to run a long phono cable, but it is possible.

Atmasphere, you got it right. Main reason for this is to move the turntable away from my electrostatic speakers. I guess I will minimize vibration and also will remove the bulk of a very big turntable, acrilic case included, from between the speakers, therefore improving sound image.

My phono pre accepts XLR inputs. I do not have a pre-power combo, instead I've got a lovely integrated that cannot be splited into two :-).

My cartridge is an Ortofon A90 and the phono pre is an allnic H3000. I don't know what you mean by "if the preamp accepts the phono signal differentially". Could you please extend a little bit.

Thanks to all for your answers.

I have an Allnic H3000 and it does not have xlr inputs. It has xlr outputs. Did you have xlr inputs added as an option?

I see no reason why you could not just put the Allnic by the TT and run xlr from it to your intergrated amp.

FWIW, Planar speakers have virtually nil radiation to the left and right of the panel, in a plane with the panel. So, you can probably get away with mounting your tt and preamp near the speaker, if you can place them in the plane of the speaker panel. (Hope this is clear to you; if not, I can try again.)

Allnic H3000 is an interesting beast. I do not know for sure that it treats the cartridge output in true balanced differential mode (presence of RCA inputs does not rule this out). As you or someone else said, it does have XLR outputs and the literature does speak of balanced output circuitry, but could be done via an output transformer. I own an Atma-sphere MP1, but I must say I would not consider trying to use 24 ft of phono cable, even if Ralph does bless it.

Very bad 2 mtrs should be max.This is a very low level signal 21Ft is very bad nobody runs 21Ft on Phono.
