OK. I am TOTALLY confused with what's going on, and what's what.
Bent MU SUT's ... the posts for loading using different resistors, is that on the primary or the secondary? I think it's the secondary.
Load of phono stage is 50 Kohms. SUT's are 1:20. Hooked up with no additional loading, the cartridge sees 125 ohms. Yeah?
This setting sounded fantastic with the XV1s, but a tad bright and accentuated highs with the UNIverse.
Adding additional 200 Kohms resitors to the posts on the SUT's, the cartridge sees 100 ohms. Yeah?
This made the UNIverse sound better, not so dynamic and bright, but a tad too dulled down. Logic would mean that I needed somewhere in between 125 and 100 ohms for the UNIverse to sound optimum.
Seeing how people have loaded their UNIverse's way down below 10 ohms, and around 6.54 ohms, I gave it a shot and put a 3.9 Kohm resistor across the posts on the SUT's. This would mean that the cartrigde sees 9.04 ohms. Yeah? This sounds really really good. With a 2.7 Kohm resistor (6.4 ohms), it was a tad too closed in for my tastes.
How is it that the UNIverse is sounding so good wayy down at 9.04 ohms and also (potentially) between 100 and 125 ohms?
And also, is 100 ohms total on SUT's + phono the same as 100 ohms on an active gain phono?
Many thanks for everyone's advice.
