Jeff Dorgay has posted a review of the Boulder 3050 monoblock amplifiers ($205,000/pair) at TONEAudio. His conclusions:
“Having spent plenty of time with some of the world’s top amplifiers, I can tell you that the Boulder 3050s deliver the goods. This is not a case of paying three times as much for a miniscule increase in performance; this is a mind bender. You’ll never be the same.”
