Is a SUT needed?

I have a Dynavector DRT XV 1s going into an Aesthetix Rhea Signature. The sound is great, but I do have to increase the volume due to the low output of the cart, which can produce a high noise floor, when listening to quieter passages.  Do you think a Dynavector SUT 200 would be a good match?  Any suggestions?

Thanks for the suggestions. I have my Rhea set at 62 on gain. Any higher and it overloads. Gain isn't the issue, noise floor is. Jperry has the the correct remedy I do believe. I'll call Andy about some tubes. I've spoken to him before-just wanted your opinions.                     Steve.

I had a Rhea and at the 62 db gain setting you should not have a noise issue with the right tubes. I bought RCA tubes from Andy on his recommendation that fit in my budget and that took care of noise floor issues.

jperry:  I too purchased 4 matched RCA 12ax7's from Andy and my noise floor was reduced significantly. Still a little tube rush between songs at high level of playback, but that's just tubes.

Curious? The tube lovers change the question about ''superiority''

into ''tube kinds''. So, obviously, there are mediocre , better and

superior kinds. Which is which is , alas, not clear.

Nandric:
I'm not clear, on what aspects makes one tube superior to another.  You read about NOS (new old stock) being the best.  It would seem with technology being so much better in our modern times, a superior new stock tube could be manufactured.  My guess is the market isn't strong enough.  Tube suppliers, such as Andy's Vintage Tubes, measure and match tubes, based on their measurements.
