''additional amplification stage...will add some noise" (mikelavigne).
I use a SUT for carts with less than 0,2 mV output. However I
will start not with ''theory'' but with practice. I own two phono-
pres both with 4 amplification stages. Basis Exclusive and Klyne
7PX 3.5 . Both recommend the use of the lowest amplification
stage in relationship to carts output. The ''theoretical'' assumption
being ''the bigger amplification the bigger distortion''. I also own
Denon AU-S1 SUT but use only with my Ortofon MC 2000 with
0.0 5 mV output. For outputs above 0.2 mV I don't need an SUT.
