Dear @mijostyn : " My mind changes all the time and in it's own little world it is entitled to do so. ..."
Yes as many of us but you changed overall suddenly in the last 2 years and I want to share with you my take about.
In the past I experienced in my system different amp/speaker set up: bi-amp with SS in the low bass and tubes in the other frequency ranges, tri-amp with different SS amps, etc, etc and through those first hand experiences i learned the critical importance of CONTNUITY for the MUSIC can flow in natural way as in live events.
You made some changes in your system ( it's not a critic. ) where from my experiences and point of view you broke that continuty in your system: first you choosed to handle the subwoofers in the digital domain ( crossover. ) against the other ranges in pure analog ( analog bass is different to digital bass ) and after that you choosed to by-amp using SS along tubes and latter you posted that now you are thinking to tri-amp with a SS in the HF range.
All those goes against continuity that's the foundation in MUSIC other than the bass range.
Only saying.
