Tube Pre and SS Power? Or the reverse?

As a young college student in 1973 I used a PAS3X with a Citation 12 for a year and loved its beautiful imaging and solid bass control of my speakers.  Later I has an SP-3a with Ampzilla...that was noisy, but the power was deleriously pleasurable.  Years of all SS ensued, until I got a C-J Motif FET preamp paired with an MV50 tube power amp.  That combo absolutely sang...one of my favorite systems ever.  I have no consistent answer!  My theory tells me tube preamp and SS amp make more logical sense, but my experience is mixed.

i think the particular interest here in this thread is the op’s actual system (his revel speakers with subs, specifically)

it is common knowledge and practice among experienced hobbyists that for many harder to drive speakers, using a tube line stage with a good solid state power amp often gives the best of both worlds (tubey imaging, tactility, fleshiness of tone -- plus solid state bass control, current delivery, cool operation)

this is why there have been many successful so called ’hybrid’ integrated and power amps over the years (by makers such as counterpoint, c-j, ps audio, just to name a few) 

but for the op’s revels, they do dip to 3.7 ohms in the bass region, probably at a fairly severe phase angle, despite their reasonably high efficiency of 89 dbm,,, then his subs handle the deep bass, so while the hybrid approach can certainly work well in this case, he may be able to drive his setup with a nice tube amp from arc, bat, vtl ... to achieve even greater tubey goodness if his room isn't too large  ... and if he can stand the cost and heat... :)

Power amp is the last stage of signal processing. If you want a true tube sound you want tube power amp too, not just preamp. Sure, if you combine, say, VAC tube preamp with Gryphon power amp it will sound excellent but it will be a modified transistor sound. 

I've had both in my system. C45 with MC275 - it sounded great. Clarity, bass, very organic. Then I tried a C2300 with MC601s. Very lush, sweet mids, great mid bass. 

I kept the C2300 with the MC601s.

I hope that helps. 

I find that the tube preamp give more of a "tubey" sound all around.

The reverse, if you want that tube “bloom” out of your hybrid system.
