I run both a sold state system and full tube based system and have found the pur solid state gives the greatest sound stage. While the Aragon 8000B paired with an Aurum preamp certainly has more power for classic rock, the tube system is far better for sound stage and high end. Why try to mix the two. Four years ago I bought a PrimaLuna Dialog 400 HP which integrates a great preamp that I improved with Bugle Boy drivers and a strong amp with their EL34 power tubes. For even more power this can be upgraded to KT120's. On top of that the circuitry can be switched from linear to triad mode and the isolated headphone circuit is fantastic. For Jazz and instrumentals the tube system gives much more enjoyment.
You haven't mentioned if you are playing vinyl or not. If so, the most important component I have found is the phono stage. I use a single Manley Chinook tubed phono stage for all three systems (Prima Luna tubes, Aragon/Aurum SS and Moth 2A3 HP amp). Tweeking the phono stage settings can make a difference that the most tone deaf listener can appreciate.
