I think the Scorpio is very similar to the Spirit 1 integrated amp, so you might be able to find some reviews on it. There’s one on Positive Feedback. The Scorpio is listed as 45wpc pentode, 30wpc triode, whereas the Spirit 1 was 50wpc and 30wpc, respectively. Other than that I think they are identical. I’ve heard a friend’s Spirit 1 a lot and it’s a nice amp. He uses it in his home office driving Silverline SR17 Supreme (90.5db) monitor speakers and it does just fine. He runs it in triode mode.
I don’t have any listening experience with the speakers you listed so I can’t comment definitively. The Spirit is pretty beefy (64lbs) and when it was for sale in the shop here I heard it play some difficult to drive speakers louder than I would have guessed, but I think it’s going to come down to how loud you want to play your system and the size of your room.
Something that you might consider, however, is that there’s an Ayon Triton 1 listed on Audiogon now for just under $5k. That’s the integrated I have and I love it. It’s a beast. If you have room for it, and it’s within budget, I’d give it some consideration.
As for reliability, my friend has had his Spirit 1 for about three years I guess, and I’ve had my Triton for about the same amount of time, and neither of us have had any problems with them at all.
Hope this helped at least a little.
Cheers,
John
