Question about loading with an SUT

I have a SUT that uses Cinemag 3440AHs.  It is set up to have various winding options (thanks Ned Clayton).  I am using it with an Apheta 2 and a Denon 103R.  The closest winding/loading to spec that I can get with the SUT is a winding ratio of 1:18 with a 150ohm impedance.  This is the best sounding setting on the SUT for both carts.  I've read that 1:20 with 100ohms is the ideal for the Apheta.  For the Denon I've seen some really wild numbers thrown out there but 100ohms seems to be the standard.  I'm wondering if there would really be much of a difference if I had an SUT with the exact ratio and loading that is specified rather than "getting close?"  It sounds wonderful now and I don't feel that anything is lacking but the devil is whispering in my ear "but what if it could be even better?"

The Piccolo MC is also quite good by the way - I find Jim's JFET head-amps to be more "musical" than other JFET stages, at the expense of higher noise floor - a tradeoff that is acceptable to me. He does use very cheap SMPS units, in order to hit such low price points. There may be some gain in 3rd party linear PSU's. 

@mulveling Have you tried a 3d party linear PSU with your Piccolo Zero?  Curious if it might lower the noise floor or otherwise benefit in the same way as a Piccolo MC might.
