Do I need a sut?

I purchased an Ortofon MC2000 cart from a fellow A'Goner, it is very low output .05mV, my phono pre is a Herron VTPH-2 which has 69db of gain and my pre is a Herron VTSP-3a(r02) 14db gain.
The cart sounds wonderful, but with such a low gain I have to turn up the volume by quite a lot. If I had, another source at that volume, I wouldn't be able to stand it. With the volume turned up so high I get a fair amount of noise between tracks. 
Should I be looking at an sut or just live with it the way it is? I found an Ortofon at a decent price, it has 24db of gain. Would that be ok to go into the mc input on the VTPH-2? The mm gain is 48db, if I plugged it in there I would only gain 3db(if I'm doing my math correctly) I will also be contacting Keith, but I thought I would ask here too.
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.

In my experience once you get to cartridge out puts this low it's pretty much impossible not to use an SUT.    Maybe I just haven't tried the right active device.

Analogluvr,  No. You haven't tried the "right" phono stage.  It IS possible to run the MC2000 without a SUT.  However, I am not about to claim that my fully active phono stage is overall superior to any phono gain system using a SUT.  I will just say it's silent and handles the output of my MC2000 with ease and headroom to spare. (It's an Atma-sphere MP1 that I modified based on the design of the input stage in Allen Wright's RTP3C.) Everything downstream from the phono input gain stage is pretty much as Ralph designed it.

@jmcgrogan2 , the best SUT for MC 2000 is T-2000 because

this SUT is made for MC2000 and 2000,mk2. Choosing a SUT

for a cart is not easy. Not only impedance but also inductance

matching is needed. However inductance is seldom mentioned

by technical specs. What does not ''match'' is the price of the cart

and the price of the SUT. Considering the price of the MC 2000

my suggestion is to try Jasmine lp 2 phono-pre. I used this one

before I bought Klyne. No problem to drive MC 2000 and impressive

considering the price (+/-$600). Besides it can be used with

whatever other cart.
