Bridging an amplifier


I recently watched a YouTube video, a few years old, that featured Flemming Rasmussen, the highly regarded founder and engineer for Gryphon (now retired I believe). Flemming was speaking of his class A monoblock amplifiers in the Antileon Evo, Colloseum and Mephisto. Flemming was expressing his disdain for Monoblocks that are actually 2 internally bridged amplifiers, (such as DNA 500,Clayton M300s and also class A Luxman that can be used as Monoblocks in the BTL mode (bridged tied load), calling these types of Monoblocks inferior and not true Monoblocks. He claims dedicated Monoblocks where all push pull transistors are paralleled, are vastly superior to summing the two channels via bridging (antiphase summing). I’d love to know if most audiophiles and engineers agree with Flemming. I have owned and found both the DNA Monoblocks and Clayton M300 Monoblocks to sound excellent, and a friend uses two M-800A Luxman class A amplifiers in bridged tied load mode (BTL switch) with great clarity and power. Thank you for your thoughts!

Well as Austin Powers put it, "Everyone likes their own brand."

On Wall St its called talking your own book.

A psychologist would probably see it as evidence of cognitive dissonance.

Me, I just see it as way too simplistic. You hear a guy talking like that, you just know he's taking something in which a zillion different aspects interact and boiling it down to the one thing. Which you know is nonsense. Which is why Austin Powers pee joke isn't irreverent, but accurate and very much to the point.
