Best tube amp or mono blocks within 5 k new/used.

I have visited my local Audio store buddies & they have a pair of demo Rogue M 120 Magnum mono blocks($2500.) My new VR-4 SE speakers are rated at 88 SPL & I would like to get full benefit of triode mode.I would be replacing a McCormack DNA-1 Deluxe.Would want an Amp that also has exceptional bass.Thanks for your responses.
