I ran a SLI-80 as well. Nice unit, built very well, great customer support, very customizable with different tube types/ brands, Triode/ Ultralinear switch, manual biasing and a remote.
The Rogue uses circuit boards where as the Cary is point-to-point wiring, if that matters. Both are well-made units with great customer support and are American made.
I ended up selling the SLI-80 since it was just overkill for my home office. I just run a little Decware Taboo (6wpc) and it does just about everything I need it to.
You can also look at the Conrad Johnson CAV45 S2 or a used McIntosh MA2275 for other options.
The best part about tube amps is the ability to customize the sound with different tube combinations. Have fun!
