Power amp for rack setup (metal, shoegaze)

Howdy y'all!

I've been interested in building a rack amp setup for my guitar rig and was wondering what I should be looking for in a power amp to achieve a solid tone for heavier shoegaze, black metal, and doom. I currently have an M-Audio Tampa preamp that I use for recording, and a delay/reverb rack unit, and wanted to see if I could find a use for these as regular playing gear.

Are there any affordable power amps y'all use for guitar setups? I'd need to find a cab as well, but was thinking my signal chain would look like this in the end:

Guitar -> preamp -> pedals -> delay/verb unit (stereo->) power amp (->) cab(s)

Thanks y'all!
