Tube Preamp with Solid State Amp?

I've been using a tube preamp with solid state amps for quite a while now.  My system is a mix of hi fi and pro sound gear.  I modified a peavey project one stack.  I replaced the tweeter driver with a selenium compression horn driver and Celestion drivers for the mid horn cabinet and Focal polyglass drivers in the horn loaded bass cabinets.  I got rid of the crossovers and switched to a dbx driverack pa+ electronic crossover.  The speakers are now tri amped with yamaha digital p7000s amps.   The tube preamp is a dared class a sl2000a model with Brimar rectifier and various 12at7 tubes.   I primarily use an Amazon fire TV cube coupled with a  hdmi audio extractor.   This way I can ship the hdmi video signal to a DVDO hd50 pro scaler and then to the projector.   I use a transparent audio power cord on the tube preamp as well as all the yamaha power amps.   I'm running balanced interconnects to the crossover and amps.  I had to make my own converted balanced cables from the rca outputs on the preamp.   From there I had to figure out the gain structure of the system in setting up the crossover.   I'm also running a pair of tc sounds 15 inch subs in stereo configuration.  I'm using an audio control phase coupled activator as the crossover for those.  All the speaker wire is analysis plus.  I'm leaving out more Information but I've probably bored you guys already.
