I'd pick the Rogue.

And here I mistakenly thought this was an audio forum and the OP asked for opinions about the sonic capabilities of the amps.
I have the Cayin 100T and like it. Hopefully in the near future I can get my hands on a Rogue Stereo 90. IMHO the Rogue exhibited a solid state like control on the bass. When I was considering the Cronus, Mark and Nick were extremely helpful. In turn, with proper tube rolling the Cayin can produce a similar low end and extended highs and it is a great bang for the buck value. Steve at VAS Industries is equally helpful.
Both are great amps. You should really try to demo them and make up your own mind. Politics not withstanding.
