tube pre amp with tube / SS /hybrid power amp ?

Having owned a couple of tubed power amps and many ss power amps as well as quite a few of both tubed and SS preamps, I generally prefer a tubed preamp with a SS power amp.

The benefit of SS amps of tubed amps is partially an issue of convenience and reliability. While I feel that one can get excellent sound out of a tubed amp, it comes at a cost as stated above. The right SS amps perform excellently with excepional reliability.

By using a tubed preamp, one can achieve a high level of the "tube" sound. This is my recommended approach after trying both combinatons.

You need to watch for synergy, obviously. Look at the dampening factors and also whether either the tubed preamp has output coupling capacitors OR the power amp has input coupling capacitors to protect the power amp from stray DC voltage that tubes are much more likely to produce than SS.

Adding some additional details will allow others to provide more specific feedback, if you are looking for any specific suggestions.

Ckoffend, your kind of input is what i am looking for.

will tube pre and SS power amp can preserve the tubey sound i am after?

so you mentioning about damping factor, whats the guideline for that?
some 10 times of the other? pre damping factor has to be around 10x of amp damping factor or vice versa?

if there is no coupling cap to protect the amp. will it be possible to install ourselves?

You are pretty much describing Blue Circle gear. Most all the preamps are tube and most all of the amplifiers are hybrid.
