Do I need a sut?

Anyone know about this one? Fidelity Research  XG-5 moving coil step up transformer with selectable input impedance.
Low - 3 ohm or lower 34dB Mid - 3-18 ohm 26dB High - 18-40 ohm 22dB
I know nothing about Fidelity Research and can't find out any good or bad info on this unit, it's as old as my cart.
Probably a "swing and a miss" but thought I'd ask.

I found one that's not pretty, but  a super price. It's worth a try, let you all know what I find out, it will be a few weeks(coming from off shore)

Thanks for all your input

Sometimes I feel like an idiot as I can only understand some of what is said here.  :)

Thanks again
Jeff

My amps are Herron M1A mono's
Output Power150 watts @ 8 ohms, 275 watts @ 4 ohms (measurements at 1 khz)
Gain24 db
Input impedance220k Ohms

So the XG-5  should work for me.

There are in and out ground lugs on the XG-5, would I be ok if I just went straight to the Herron phono pre with the output ground from the turntable? 

Thanks
Jeff

Raul,
I did purchase the FR, but now I'm trying to see if I can back out of that purchase(if it hasn't shipped yet). I did previously send you a couple e-mails requesting your advice, but maybe you didn't receive them, that's why I posted here.
Thanks
Jeff

Raul,
I have no desire to spend another $1000-$1800 for a T-2000. That makes this cart really, really expensive.  I'll keep looking and maybe eventually something will come up at a more reasonable price, in the meantime I'll live with it the way it is, the cart sounds great, just bothersome when there's no music.

Lesson learned :)

Thought I would put out an update. I put it the FR XG-5 and it didn't stay in long, the noise was increased dramatically.  Then I put in 4 Telefunken 12AX7 tubes which raised the gain on the phono pre and it did reduce the noise by quite a bit. Then I had a discussion with Keith Herron, he said he could increase the gain in the phono pre with some FETs, but wasn't a proponent of doing that. He suggested that I try rolling some 12ax7 tubes to see if I could come across with some that worked better. So I did some research and found some info that Gold Lions had higher gain and were still very quiet. So I just received a quad that I purchased on E-Bay, listening to them now and the noise is reduced to where it's almost unnoticeable. no worse than a noisy record. Granted they're brand new and we'll see when they see some wear, but right now things are sounding great.
I really appreciate the input from everyone.
Jeff
