Reliability of Dan D'Agostino equipment

I have no firsthand experience with the brand, so I can't speak from experience. However, there is a YouTuber I follow whose channel is devoted to ultra high-end audio (Wilson, Magico, Gryphon, Boulder, Pass, etc.), and the members-only section of his website includes a video in which he discusses brands that have a reputation for reliability issues. I would recommend checking it out. The channel is Jay's Audio Lab. By the way, you would think that any insanely expensive audio gear would last a decade or more without issue. That's what I thought too. Two equipment failures and Jay's video changed my mind. 

If it’s electric, it will have issues, if it’s a Ferrari, power amp, 

things fail. Inevitable

I have a Progression integrated amp and is has performed flawlessly for the two years I have owned it. Before buying, I borrowed it from the dealer to compare it with my Pass Labs INT-150, and the difference was obvious to everyone that listened to it. You can't "unhear" just how much an improvement there was in SQ, so I bought it. Glad I did.

No issues with my D'Ag gear, or prior versions.  But agree with the car analogy; Ferraris and Astons still need attention, things can happen (I've had very infrequent issues with some other pricey audio stuff and I don't automatically disown the manufacturer), and owner error can be hard to anticipate/prevent.  I visited D'Ag outside Scottsdale last year, and they were terrific, gracious hosts for a nobody like me.  

I feel like amplifiers that get into the five and six digit range especially, should be covered by a warranty that’s longer than that of a vehicle. One of the brands that really stands out who put their money where their mouth is, is Bryston. A 20-year warranty that is transferable speaks volumes about how a manufacturer stands behind their product. I have owned and still own a number of Pass Labs amplifiers and can only comment on what I’ve owned. I have never had an issue with my x-600 monos or my X150.5. Ever. The D,Ag products are certainly one of the most beautiful looking amplifiers I’ve ever seen in my life, especially since I am a meter guy. I cannot say that I have yet auditioned their new amplifiers but I did just buy a house out in Arizona and would love to go check them out. DS
