I really don't think there is an easy solution to the obvious question - which is the best processor, it will depend on how good or bad your room is, how the processor works with you amplification and front end(s) and how good the set up is (you or a professional) getting to the bottom of this is not a 10 minute exercise so the 'perfect' choice is hard.
I also understand given how complex they are and with this complexity means their all be design and build compromises necessary with some of the sub £4k processors
Having listened to most of the high end processors in demo rooms, none were 'bad', I really like the upgradeability of the Trinnov (software) but the constant HDMI changes mean that hardware will also need investment depending on the use and this is very expensive.
With a 7.3.0 I am very happy with a very old analogue out set up and overall preferred the trade of resolution, spatial positioning and control to the organic flow, musical timing and tonal density I get using a 15 year old naim unit vs the Acurus ACT4 (in my set up), I am sure some would disagree and that brings in the other variable - your preferences because it is and always will be a compromise, nothing is perfect or even close. The best processor will be the one that provides the best compromise in your set up. Whilst this might seem negative, it is realistic as these amazing units will be the old Meridians or Lexicons in 10 years time with something else taking over pole position with less but still some compromise.
I think those with a Trinnov are likely to keep it for longer and 15 years use that 'only' £1k a year for your processor - cheap really !
If I had overhead speakers, a challenging room and deep pockets I'd be home demoing the Trinnov , Storm and Lyngdorf as well.
