SUT experience

Sorry, I am not steeped in knowledge of the SPU series and so did not realize what you were talking about. With the Synergy (0.5 mV), you definitely do not need the 60db gain setting. Even 50db is slight overkill with a 1:10 SUT. For example, with the SUT the cartridge, and SUT are dumping 5 mV of output into the phono inputs. That is the typical output of a high output moving magnet cartridge. With such a cartridge, usually only 40 to 45 DB of phono gain, along with line stage gain, are more than adequate.

nevermind was Gilda Radnor's bit 

Dear @adrianleewelch  : " new to the SUT game and it was a game changer. "

Well, with the SUT you are adding " new " distortions that came from the additional IC input/output RCA connectors along the cable and solder joints plus the distortions developed by the SUT transformers.

Your McIntosh  unit has not high quality phono stages, it's " so so ".

Maybe could be a good alternative to own a new dedicated  phono stage as the PS Audio Stellar model that's not to expensive. You could try and maybe you can find out a true game high quality changer. Yes, you need those addituional IC to connect in the C47. This is that unit, please read it including its real time measurements:

Now, if you decide not to go with that alternative then you can improve the sound quality performance rewiring internally ( for better quality wire. ) the Entré SUT and changing all its input/output RCA connectors.

Regardas and enjoy the MUSIC NOT DISTORTIONS,

Wow @rauliruegas , that was really popping the OPs balloon. @adrianleewelch 

Unfortunately, Raul is correct. Your best way forward would be with a dedicated phono stage. You might also want to look at the Channel D Lino C, it is a killer phono stage for the price. Transformers can do very well if they are installed inside the unit, no ICs. In Macs there usually is not enough room,

I might also add for the future that the performance of a cartridge is greatly enhance by the type of stylus used. You never see conical or elliptical styluses in high end cartridges. The best are the fine line contact designs like the Soundsmith OC-CL, the Gyger S and the Replicant 100. When looking for a cartridge at a reasonable price find the ones that have the same features as the best like boron cantilevers and fine line styluses. A good examples would be the Goldring 1042 and the Nagaoka MP 500. Just install the new cartridge in the SPU's head shell and your brain will think you have a classic:-)

Raul, I don’t know if the Project phono is better than the Mac phono built into the OP’s C47, but in any case he’s using the Project for phono gain and RIAA, not the Mac. And I don’t see the point in raining on his parade. Nor does his budget appear to allow for a Lino C phono stage. He came here for a little SUT education. I hope he got it. With all his gear, knowledge of the art is indispensable.
