Will VPI's Classic 3 sound much better with a SUT?


I'm considering adding a SUT to my vinyl rig, which already sounds detailed and neutral which I prefer. I may add Bob Device's VPI specific SUT ($1,750).  It would replace the existing RCA junction box on the arm board, so no added cable needed. 

Please have you the same/similar SUT experience with your same/similar turntable?  What was the sonic result(s)? Thank you!

PS My vinyl rig in more detail: Ortofon Cadenza Black MC, VPI Reference wired 12" 3D tone arm, Tara Labs RCA cables to Fosgate "Signature" tube phone pre-amp, Tara Labs RCA cables to Unison Research "Unico" integrated amp, Nordost "Frey 2" speaker cables to Definitive Technology "BP2000" floor standing speakers.

Your Fosgate has 60db of gain. Enough  for most of the popular MC carts.

Former owner of  one for 12 years- great phonostage. Get a different  cart for a different  "sound" Also a longtime VPI Classic user

If you're  seeking  dramatic improvement dump the VPI/Fosgate and open the wallet wider. 

You will hear less tube rush at high volume with SUT-MM setting if you're the type that listens for it.

Needless expense, IMO.

lewm: Your math is off! The Fosgate mc stage amplifies the signal about 10X. So .3 mv becomes 3 mv. That is enough for a typical phono stage. You didn't figure in the gain of the Fosgate preamp's line stage. Most line stages can output several volts. Plenty to drive power amps, which typically need 2 volts for full output.

Jason, I don’t know where to begin. But 60db of gain provided by the MC stage in the Fosgate equates to a 1000X voltage gain, and a 10X gain that you claim would be insufficient for any phono stage ever. 0.3mV multiplied by 1000 = 0.3V

Also, I didn’t figure in the gain from the linestage because I cannot find any information on that and because most integrated amplifiers don’t add linestage gain. So I’m guessing the linestage (which is probably just a volume control ahead of the amplifier input stage) adds no gain. To support that assumption I found that the UR has only one tube that drives its mosfet output stage. That leaves no gain device available for any sort of linestage gain.

No need to spend $1750 on a Bob's SUT! I have five SUT's. My Bellari is a favorite! Only $350! It sounds excellent with my Denon 103R! 

The typical mc stage magnifies a mc cartridge voltage by a factor of 10. So .3 mv becomes 3 mv. Adequate for the typical phono stage, which I assume the Fosgate has. I am sure the Fosgate line stage can output several volts. So plenty of volts to drive a power amp.
