I recently purchased Dan's integrated which replaces a Stone Age (but still very viable) Jeff Rowland 8T and BAT VK-51SE. I have heard Dan's separates, but I can't fairly make a comparison since the rooms and associated equipment were vastly different. For lovers of "industrial art" the D'Agostino products are gallery worthy. When I purchased mine, I jokingly said I would love to buy the guts of the device wrapped in Aluminum foil for half the price. But, true confession, it really is a pleasure to use such a well-machined product. Every dial, knob, button is precision crafted.
As for the SQ, I can't rank it with other topflight comps since my audition conditions/ associated equipment have been different. I will say this- no buyer's remorse! I was a self-professed tube lover. With Dan's integrated I don't miss them. I bet most blindfolded listeners would not be able to tell if it is SS or tube-based; it provides the best of both without the stereotypical features of either. Playback is effortless with my somewhat-demanding Rockport Aviors. I'll skip the reviewer-style specifics. This is a topflight machine! Are there better ones out there? Probably. But as impossible/impractical as it is for any of us to compare all of our product candidates- in our own listening room with our own associated equipment is- it's hard to imagine missing anything while enjoying this one. Gotta go, back to the music! With no vested interest- the D'Agostino is amazing.
