Transfiguration Phoenix S cartridge - impedance loading recommendation?

This cartridge has a low internal impedance of 1-2 Ohms, and the manufacturer recommends an impedance loading of >7 Ohms.

My phono stage (Accuphase AD 2900) has MC impedance settings of 10, 30, 100, and 300 Ohms.

I have tried it at 10, 30, and 100 Ohms and they all sound ok.  I am running it at 10 Ohms for now.

What settings have you found to be best?


Dear @toronto416  : MC cartridges are not sensitive tochanges in loading impedance but a " not so good " phonostage design it couldbe.

I owned the Phoenix and other Transfiguration models, the one you own is truly and has a very  good quality performance levels.100ohms is OK. Your Accuphase unit is very good design too, so no problem at all.

I own a Transfiguration Orpheus L, which is also a low impedance cartridge.  It is not sensitive to loading and I run it with 360 ohm loading.

If the internal resistance of the Transfig is 2 ohms, not 1 ohm, you might be slightly better off setting the input impedance of the Accuphase to any number above 10 ohms. This is only because you want ideally the input Z to be at least 10X higher than the output Z, for any two components where one drives the other. It primarily affects the efficiency of energy transfer, in this case signal voltage. The rule is rather plastic when it comes to phono cartridges driving phono stages, so I would not worry about it much, but maybe try 30 ohms or higher and see whether the system becomes a bit more dynamic or produces higher SPLs at lower settings of the attenuator. In some cases, where the inputs have some capacitance, the ratio also affects transfer of high frequencies. In the case of a bad mismatch, you’d expect some audible roll-off in the treble region. I doubt that would be a noticeable problem with your current choice of input impedance.
