Is a SUT needed?

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. 

sksos1:  i'm just a few blocks from you down in Nashville Tn.

I'll drive over this weekend!😎

There is no substitute for trying one or more in your own system to hear the effect.  Bob of bobsdevices.com sent one of his SKY10 SUTs to me and Wow!  Huge improvement.  My phono stage is cj TEA2MAX, 55 db, using an Ortofon Winfeld with 0.2mV output.
