Is a SUT needed?

Jperry:  Thanks for the heads up. I could have easily invested twice what I already have, to no avail. I'm pleased with my sound. It's all good. 

handymann ~ I'm sure your analog system "sings" and yes tubes can make a world of difference but again it's my opinion (after trying to perfect my alalog rig for close to 40 years now) that a MM phono stage used with a step-up transformer will usually outperform a MC phono stage alone in most parameters. 

A SUT & MM stage are like a peanut butter & jelly sandwich you can't have one without the other.  

HAPPY LISTENING

Sksos1:  That's why I'm using two different MC carts. No SUT needed. Maybe a SLUT😁

Sksos1:  All joking aside, I had a Clearaudio Maestro and it sounded great. Didn't have it connected to an SUT. It had plenty of output. Maybe I need to invest in a SUT to up my voltage. .5 mv is a small amount of output for sure. I know with any kind of input, u need good up front volume. I wish I could try a SUT out to see if I liked it. 

handymann it's not that a MC phono stage doesn't have enough gain to drive the output of the MC cartridge that's not what I'm talking about.It's that a MM phono section is usually easier to build and doesn't require an extra stage and then when you add the SUT to the MM phono stage the magic happens. You would never use a SUT into a MC phono stage b/c for sure you will overload the system.
If you live in the Boston area I'd be more than willing to come over with several SUT just so you can hear what I'm talking (listening) about.
