3 but, contrary to this, the popularity of sut (step up transformer) is on the upswing. So many people were telling me how putting a good sut in front of their phono preamp brought out a rich, lush and emotive char- acter that was completely seductive. People were passionate about the sound quality....
Page 4: The Correct Question:
4 the correct question: since customers can always add a sut in front of any sutherland phono preamp, this approach is already available. Many people were doing just this and enjoying the results. So the question became: is there better way? This question was further modified under the sutherland ph...

5 the appropriate answer first, the sut needed to sit directly on the preamp circuit board. This decision brought with it many advantages. The connections between the sut secondary and preamp circuits were now as direct as physically pos- sible. The distance was minimal. The inter- connecting cable ...

6 the question of how to offer loading and gain options is a tricky one. All solutions have advantages and compromises. For the mcx i decided on the most simplified signal path — along with flexibility in values — as the high- est priority. The loading and gain resistors plug directly into machined ...

9 the mcx ships configured for a gain of 60 db and a loading of 200 ohms. This will be a good starting point for most systems. If you have different preferences, please refer to the gain and loading pages. The two mcx are designed to be stacked on top of each other. Plug your turntable into the in j...
