Preamp comparison- need help

I have a Cary SLP98P and I'm getting all new Ruby EL 34 tubes 2 EL84's and 2 12ax7 input tubes for my Cary V12R amp in a couple of days. I tested the amp tubes and deceided to just get a new set. The SLP98P ran very good when I still had my McIntosh 7270 amp. Still having both a tube amp and preamp is even better. I love both units and have not rolled any tubes yet. I used to do it the hard way and roll speakers. I've been single for some time now.

Modwright, Bruce Moore, Cary
Have all three and that's the order of finish.
Win, place, show

Modwright SWL 9.0se with tube rectifier, u cannot go wrong with this.
