Tube Preamp and SS Amps - How?


I am considering moving to a tube preamp and SS power amp set up. Are there any rules of thumb in getting a proper match and what should I look out for or avoid? Any suggestions or insight would be greatly appreciated!!

Thanks!

Well, there's that the ouput impedence of the pre should be 100 times less than the input of the amp thing. Rule of thumb stuff, so they say. Its not uncommon to run in to an impedence mismatch between a tube pre and a solid amp, so set your calculator for 100X when surfin' for amplification.
I dont know maths, also dont cal maths, life experience:

Jadis DPL2 + Meridian 505 mono
ARC LS2 MKII + Pass Lab 150

Jadis sounds very romantic, but losing bass. ARC combo more dynamic, but lack a bit power (may be Pass Lab need to be replaced something).

However, I believe things should work better in the same character.......tuibe with tube, ARC with ARC, Jadis with Jadis, Meridian with Meridian, etc
If you want a look alike pair that are made for each other, then look at the Blue Circle BC21.1 preamp and BC22 MkII amp.

The Conrad Johnson PV10 also works well with solid state from my experience.
Ohlala gives good advice with his 100X formula, although, sometimes satisfactory results can be achieved with less difference than that. Generally, tube preamps have higher output impedance than solid-state units, and transistor amplifiers often have lower input impedance than tube models and that's where the potential for mismatch creeps in. If you own a unit now that you intend to keep and use, then the 100x formula should be a consideration in your search for a matching piece. I usually like to see around 50k input impedance in a solid-state amp, as that will mate well with many tube preamps. Then, using that 100x formula, you can go up to 500 ohms output impedance (or thereabouts) in the preamp without a problem.
Just for clairfication. My Ayre V-3 states that it has an input impedence of 100K per phase. That means I can have a pre-amp of up to 1,000 ohms output impedence or does the per phase effect the formula? Thanks!
