Experience with Rogue Stereo 90

I'm thinking about purchasing this amp to drive Spendor s5e's, which are only moderately efficient (specified at 88, but tested to be 82).

Does this amp have sufficient power to drive moderately difficult loads? Also, is it capable of producing tight bass?
I drive Martin Logan Aeons (89db, 4 ohm nominal) with a Stereo 90 with no trouble at all, and it gives great bass.
