Vern, as you went with the progression monos, did you by chance compare the Dag Momentums to the Progressions (with Ref10 pre) before making your choice? I’ve not seen a lot of chatter comparing the two?
Hi Bob!
As Vern said, he'll get around to comparing the two himself, and we also compared them. It's really remarkable how Dan has made two different amps that sound different, yet possess the same overall character.
The differences were less pronounced on Wilsons, since they're more efficient, but on the YGs, the extra headroom afforded by the Progression was very much welcome, in a large room! That extra couple hundred W really does make a difference in sharp transient attacks...
I have a client who auditioned the Momentum, and thought it was pretty much like a beefy tube amp (and he knows, because that's precisely what he has!). To my ears, that's the extra level of refinement the Momentum has, that renders the midrange just a bit closer to real, with the typical tube-like bloom.
cheers,
