The sound of glasswear

There has been lots of talk here about the virtues of using tube preamps with solid state power amps . I'm faced with the opposite possibility , I love my solid mistake preamp way to much to part with her and am wondering if a tube power amp would be a good move . I'm not complaining about any aspect of the sound now , But an amp is in the near future and I don't want to close the door and my ears on any technology , see system link for details if you must . Will this work or has anyone tried this with a fairly large tube amp ?

All of the tube amps Ive run, would just run out of power, or make racket through speakers, but not go DC.

A couple of links of the net about newer amps still going DC, and blowing speakers. [http://www.diyaudio.com/forums/solid-state/116149-cambridge-audio-a5i-blown-speakers.html][http://www.htguide.com/forum/printthread.php4?t=34748]

From looking at these links, neither seems to support the kind of scenario that involves a preamp. They both look like some sort of malfunction in the amplifier.

Many SS amps use a protection relay or similar circuit to detect DC at the output of the amp and either disconnect the speaker or shut the amp down to prevent damage. A relay that disconnects the speaker will be an impediment to getting the best sound out of the amp, so (oddly) we are back to where we were in the 1960s when speaker protection circuits were rare.
