24 feet DIN to XLR phono cable for Graham Phantom?

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.

Jbuenech, if the XLR input is done via a StepUp Transformer, then you will get the benefit of a proper balanced input as the Common Mode Refection Ratio at the input should be quite respectable, this so long as the SUT is tied to pin 2 and 3, and ignores ground.

Sarcher30, you are right. When I tried with a shorter cable I found out that XLR was the phono pre output, not the input. As my integrated amp does not have Balanced inputs, my only option is to put the turntable between the plane of the speakers, as Lewm suggests.

Thanks to all of you for your contributions¡

Dear JB, Dipoles radiate in sort of a figure 8 pattern where the pinched part of the "8" represents the radiation at the plane of the speaker, and the two top and bottom loops represent the radiation patterns in front of and behind the speaker. So you should be ok. This is also why you can get away with having the outer edges of the speakers very near to side walls.
