My experiences to date is that when one surmises about a outcome, it is quite similar to advertising, in the context, the individual is forming a pattern of thought on selected words only and not evidence, through their own direct experience.
I know the 834P Phonostage very well, I have been demo'd it on numerous occasions as a EAR and Clone.
Neither versions have been able to take myself to the place I want to own one.
I have not been demo'd or compared the 834P MC with any of the other EAR's mentioned, which makes it difficult to give an accurate description based on my preferences.
I have been introduced to the MX4 last year for a short duration, and can confirm, it has a lot that is making a model, one would like to have an extended experience of, especially in the home system.
I still claim the Sculpture A SUT's with the nano-crystalline core, is the SUT I will be trialling at home in the future, the impression the two models from this brand made during the demo's has been indelible.
My Mr Nixie DIGNA has been compared at Bake Off's to a selection of 834P's and I can say the DIGNA is much more to my liking, especially with an off board SUT in use.
The DIGNA Built in MC Input has been very much enjoyed by most who have heard it, including myself, but the SUT used for my preferences has the edge.
The Local HiFi Group selected this design as their choice to compare Analogue items for nearly a year, or until another member had a Bespoke Built Valve Input/Output Phon' built to very similar Spec' to my own Bespoke Built model.
Today I will allocate the DIGNA approx' 30% replay time, as it makes such a good impression with a SUT, with a Head Amp I loan, it blows me away on Rock.
