Boulder vs D'Agostino

[Antonmb]

I've been considering an amplifier upgrade for a while, and am now in a position to pull it off. I currently have a Linn Klimax DSM running via balanced cables to a Linn Klimax Twin amp. The Klimax DSM is a keeper, shortly being upgraded to their latest Katalyst DAC architecture, but the amp will be the weak link. The options I've been looking at are the D'Agostino Momentum stereo and Boulder 1160, both of which are available relatively locally. There's a lot of info out there on the Momentum, but not so much on the Boulder. I'm trying to arrange home auditions, but it may take a while because of logistics and the dealers both have the monos, not the stereo. I can listen to both at the dealers, but unfortunately they're different dealers with different systems, and neither has higher end SF speakers available.

Does anyone have any experience with the Boulder, either this new model or its predecessor the 1060? Or anyone have experience with both Boulder and D'Ag, especially with Sonus Faber speakers? Any thoughts on one vs the other?

Thanks
