I see you have (had/solved?) an issue with lack of bass from your TT (mentioned in a prior discussion). I would not expect the MP1100 to change/solve that, if that is what you are hoping.
I've owned and used for many trouble free years: McIntosh, MC2250 SS amp; C28 SS Preamp, and now use and love the sound/features/of a McIntosh Tube Tuner/Preamp mx110z. Vintage: I solve remote volume and remote balance separately. If my mx110z dies, I will probably just get another one rather than risk .....
Eventually I had some hum develop with the C28 Preamp, turned out to be an internal ground solder connection that mysteriously loosened.
Prior to the hum, I did not prefer the sound of it's SS MM Phono Stage, whereas I love the sound of my mx110z's Tube MM Phono.
