Congrats on your choices and your process of decision making. I was cringing as I was reading through the posts which unfortunately I did not begin to read until minutes ago and so my feedback does not matter much now as you have made your decisions.
That said, I just feel compelled to throw my two cents in and if it helps great, if not, you only lose a minute of life:
I have tried two dozen different turntable and cartridge combinations and every combo has plus and minuses that I sometimes hear quickly, but most times do not discover until I have 10s or 100s of hours of listening time in.
Since you bought your rig already, please make sure you take the time to balance the TT, arm, and cart, aligning the cartridge length as it sits on your tonearm and the angle at which the stylus rides in the groove (VTA). The weight of your cartridge affects your tonearm in the way that it rides in the groove, and you need to adjust, listen, adjust, listen, and repeat a few times until you get the most balanced sound quality over the widest range of the album (from outside to inside grooves).
Until I learned to take the time to do this with patience and precision, I found I was rolling through cartridges always looking for "better" sound. Several carts and thousands later, I was back to the original suggested cart for my TT except this time I REALLY took the time to adjust it over and over until I was very happy with the sound. I have not changed it now in over a year.
And, if you find yourself looking to upgrade your phono stage, I would suggest staying away from ProJect as I have tried all their stages, and they are just OK...I have an RSA F117 Nighthawk now which is a battery powered, gain and load adjustable phono from Ray Samuel and this thing is as close to a $3K to $5K phono stage I have heard yet for about $800. I have compared it to the Einstein when I was buying it on a $100K setup, and the Einstein turntablist was slightly more revealing (at $4k) and I have compared it to a Cambridge 650 and it was not even close. The RSA amp has been the most significant upgrade I have made to the sound from my vinyl since I stopped swapping carts like they were cables (which is another story).
Enjoy your setup, I love my vinyl!
