Wow that is interesteing that you owned three different sets before it dawned on you that you had issues with them.
I am not suprised that the Rogue audio setup wasn't good, it is not a tube thing, it is a complete system matching thing.
When you have a cool speaker, ie one with very low levels of coloration and you want them to sound musical you have to add some warmth and body to the sound somewhere. Just because you use a tube doesn't mean you have solved the problem.
Yzsantabarbera commented that the room was way too small, I wonder what the reset of the chain was, were they using Audioquest or Nordost cabling? Did they have a suitable digital front end? Did they employ any room treatment or was the room ringing with slap echo.
That is one reason why we invite people over to our showrooms, we dial in our display systems and we use all the tuning tools and accessories to make our systems sound musical.
So before you bash the speakers perhaps blaim the setup.
As per hearing individual drivers I find that remarkably strange, the Persona use the exact same material for the tweeter and midrange, what you may be having an issue with in terms of integration can happen if your sitting distance is not correct or your rake angle is wrong.
