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?"

I know this isn't going to do any good, but I'll advise you not to worry about it.

From my understanding, when using a SUT, gain tends to play a more critical role than loading.

That said, if you're already getting great sound from both cartridges with the same SUT, I wouldn't worry about it as mentioned by others. By the way, you didn’t mention which phono stage you’re pairing with your setup.

I have a DL-103R feeding into a Cinemag 3440 with switchable taps for 1:18 (150 ohm) or 1:36 (37.5 ohm). I use 1:18 and it sounds lovely. I also have a Rothwell MCL with 1:20 (100 ohm) and I honestly can't hear a difference between these two SUTs. I've switched back and forth many times and settled on the Cinemag.
