Too good to be true?

I recently purchased an XA25, and I have been delighted with it.  It replaced a highly regarded 300B-based tube amp I had been using, a 70 watt per channel class A biased VAC Renaissance 70/70 MkIII.  I found that the following review by Terry London (Audiogon member Teajay) described its sonics perfectly:

I should add, though, that my speakers (Daedalus Ulysses) are very easy to drive, having a very benign almost flat impedance curve, as well as 97.5 db/1 watt/1 meter efficiency.

Also, see the comments by some other owners as well as myself in the following thread:

Mine's going nowhere for a long, long time.  I've had Sumo, Bryston, Classe, Audio Research and Ayre.  This is the one.  Balls, finesse, presence, extension, transparency, ease.  With my 90 dB Acoustic Zen Crescendo 2's, it's perfect for a condo.

Thank you, Gentlemen!  I appreciate your comments and opinions.  I own a pair of Martin Logan 11As.  The speakers are rated at a 91db as far as sensitivity in concerned.  Do you think this Pass amp is sufficiently powerful to drive the Martin Logans?  I don’t usually listen to extremely loud music and my tastes run to progressive rock, female vocals and pop.  Currently, I am using a Benchmark AHB2.  Again, thank you for taking time to respond and I appreciate your advice!

^^ That will depend on the room size and how lively it is- as far as will the amp drive the MLs, yes it will. In a larger room you may run out of gas; in a smaller and some medium sized rooms it will be just fine. The genre of music won't make any difference- electronics and transducers don't care about that :)
