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?

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.

Glad to hear my suggestion helped with your problem. I assume you just replaced the V1 and V2 position tubes left and right. Those are most sensitive to noise issues.
Is an SUT needed? No but IMO (only) I find an SUT into a MM stage gives me superior results.Better dynamics more detail and a more natural presentation. I've tried many SUT's and have found the Kondo SFz step-up the best until recently.  I have recently tried tbe SA Labs SUT from Russia to now have outperformed my beloved Kondo unit, and at a less expensive alternative.
