Still working on choosing a power amp

System: Rogue Audio Perseous Pre amp, Rogue Audio ST-90 Power amp, Krell SACD Standard, Project RM 10 TT, B&W 803s speakers, Staight wire cables. Have been researching options for a power amp. Thought about Rogue M-150 monoblocks and some others. Would there be a sound conflict if I use the Tube preamp w/ a solid state power amp? It seams there are more options for higher power amps that are SS. Therefore more headroom. So, what's the deal? Do you loose the tube sound?

Yes, but do you think you loose a little of that tube sound?

Bob,
The Rogue Perseus has an Output Impedance of 450 Ohms. Does that mean the input inpedance of the power amp should be 4500 ohms? So, for example the Mcintosh line of SS amps have an input impedance of 10,000 ohms... therefore would that be a poor match?

Thanks, for all the responses. Yes, I like the tube sound. Yes, I play the unit a bit on the loud side... but, just a bit. I feel my system is lacking. I am currently demoing a MC402. The speakers have really opened up. At 8oms a little too bright. It was like someone turned my tweaters on for the first time. At 4ohms, not as bright. A much more true sound. From what I have read and experienced the B&W 803s's require power. Would love to demo the Rogue M-150 monoblocks. No dealer carries them here. So, that poses another problem.
