Solid-state preamp with tube power amp


How important is it to use a tube preamp with a tube poweramp? Will a solid-state preamp "undo" the tube effect of the power amp?

Hello all,
When I use Klyne pre-amp (SS) with Lectron JH 50 (tube amp), music sounds awesome. It sounds somewhat different when I use NAT Plasma (tube pre-amp) with Conrad Johnson
MF-2550 (SS) amp, but I would not say either combination sounds more satisfying than the other. The speakers are ProAc Response 3.8.

As you've no doubt discerned from the above posts, it's all relative.

I've been in this hobby for over 45 years. My $0.02 is that it is easier to build good sounding solid state components AT A CHEAPER PRICE POINT (e.g. sub $1,000) than it is tubed.

Which explains the popularity of Schitt products. They deliver tremendous value at their price point.

I used to have Martin Logan Spires (recently replaced with Coherent Audio GR 12's, which are 96dB). I have both solid state and tube monoblocks. They are fed with a Don Sachs 6NS7 tube preamp. 

My s/s monoblocks put out 900W into 4Ω.  My tube monoblocks output 75W. 

The tube amps lack the punch of the solid state but sound more musical on instrumental recordings. Tube rolling becomes more complicated/exciting when combining both tubed pre and amps in your system.

If your speakers like big power (like Martin Logan's), then a solid state amp is a 'better bang for your buck' than tubes.

YMMV.

Been thinking about this a lot myself... have a simple Sonic Frontiers, SFL-1 (Electro Harmonix tube) with a Cary "Rocket 88R" (Gold Lion and Raytheon tubes). Speakers in and out although right now a pair of very efficient Equation "7". It all plays incredibly. System synergy being the primary quality although the Equations are special. I have a chance to try out some interesting pieces. 1st, sub out the SFL-1 for a Luxman (Lab Series) 5C50 preamp. See how that plays and then pull the Cary for a Class A Sugden, Bijou Ampmaster. Going to play around a bit and see where, if any, the improvement lies. Nice to have access to such fine components
