Alternatives to Rogue Stereo 100

I've been thinking about adding a tube component to my heretofore all SS system.  I've got the opportunity to pick up a new Rogue Stereo 100 power amp for about $1000 off it's normal $3495.  I'm familiar with its reputation, and I'm wondering if there is anything else in that price range ($2500) I should be considering.  I've got an Ayre pre and PMC TB2i speakers, and my sources are VPI turntable and Mytek DAC for all things digital.  PMC's are 90 db sensitivity.  Currently running a Primare SS amp, but I also have an Aragon 8008MKII.  Between the Ayre and the PMCs, my system is probably a little lean, and I'd like to hear what a good tube amp will do.  Mostly classical and acoustic and "audiophile" stuff on this system.  Save the heavy stuff for downstairs.  Appreciate any feedback.
