Both brands have their share of accolades in the industry and among audiophiles. I am not sure about the Aragon ST, if it's similar to the 8008BB, then, it's pretty powerful and should have no problem driving any difficult or inefficient load. I use an Acurus A250 which I think is similar in some respects. And I've heard Aragons and Brystons drive difficult Magnepans in the systems of a few of my colleagues. They are both knwon for their uncoloured flat freqeuncy responses. If your speakers are a little thick in the midband, then either amp will just reveal that easily.
But if I were to choose, all else equal, I'd go for the Bryston. If only for the fact that I am not eactly a fan of Klipsch products whose owners bought the Aragon brand. Klipsch is a speaker company. They may be diversifying but I don't know how they plan to further the interests of the Aragon brand. OTH Bryston remains a Canadian electronics company which by all indication remains strongly dedicated to their amplifier products (though they also carry the PMC loudspeaker brand as well.) I don't know if Aragon issues a 20-year warranty, but Bryston does. And that speaks volumes about the Bryston amp. But that's just my opinion. If you can audition these amps paired to your Energy Veritas or similar speakers, better for you to make a decision.
