I agree with Nsgarch, tube amp has much more influence on the sound than tube pre amp.
I also started with tube pre and solid state power 20 years ago, only when I changed to a tube amp I discovered "tube pre + SS power" is for the wannabe. Same goes for hybrid amp, they only do half of the trick or less.
From impedance perspective, it should not be an issue for most tube amp to preceeded by SS pre amp, but not the other way around. Best option like many suggest is to use tube pre, it will take your system to a whole new level.
