Does Everyone Use 2 Phono Cables with SUT

Huh?

that cartridge has a difficult combo of high 16 ohm impedance and low .23mv signal.

It is the type that might need a SUT with individual gain adjustments and individual impedance

what SUT are you using? You need to know the x factor of it’s input(s).

cartridge .23mv; allowing for some loss: an x factor around 20: that would give you a signal of around 4.0mv., plenty for a MM Phono input.

resultant impedance of xfsq 400 shown to a 47k mm phono input would be 117.

guidance for your cartridge, 16 ohm x 10 = goal of near 160 ohms shown to MM Phono input..

to get ’shown’ impedance up, you need to lower the x factor.

x factor 18 signal after bit of loss 4.0mv, still plenty

xfsq now only 324, 47k/324: shown impedance now 145. closer

x factor 16, signal say 3.5mv, many MM and High MC have this or a bit less. your MM stage has a ’sensitivity’, that is just above too low.

xf16, xfsq 256; now ’shown to 47k input would be 183.

now back to the issue of cable loss!

And here I thought that phono cables WERE interconnects.

The post reads to me:

"Better SQ from better cables."

BFD

No clue what everybody or anybody else has any bearing.

Definitely makes a difference to use a “true” phono cable from SUT to phono pre. Also most phono interconnects come with a grounding cable, some installations may require this some may not, every situation is unique. With my own set-up my Kuzma 4Point comes with RCA cables at the back end and then connect directly to the catridge pins, which is still like using a dedicated phono cable from arm to SUT.

Rather than confuse with labels, as has been noted above the sut to phono preamp cable should be excellent and low capacitance. Doesn't mean expensive per se. The lowest capacitance cables will be unshielded. Your phono pre might be better with shielding and this might raise capacitance slightly. It's a balancing act.

As an aside the lowest capacitance pro cables tend to be coax designed for instrument.

Short lengths are key
