If you are at all considering a tube integrated amp, you might give some thought to the Rouge, Cronus Mag. II. When home auditioning some very nice power and integrated amps to drive my Maggie 1.7s ( a bit more difficult load than the PSBs) even over the Prima Luna Dialogue HP, I chose the Rouge. With the Maggies, the Rouge did every thing as well as the Prima Luna (very open and detailed, yet smooth and musical, with a very large stage and very good imaging) but with less effort and a little less heat. The Rouge was also a bit more dynamic with percussions and base. Just a thought,
