Doozy of an amp question

Still looking for my eternal love.

A forever amp. At least for now. I cannot try them out in my system as they are both beasts and it would be a nightmare getting them, paying for an audition and then returning them

I am having to go on instinct.

I have narrowed it down to two very different kinds of amps at two very different price points. And I have chosen these two because of reviews in magazines and the positive comments here and on other forums.

My pre is an Arc Ref 10 and my speakers are Dalis.

I am look at a tube Mc 1502 which I can afford right now or a Sim 861 for which I would have to wait to save for.

I realize it’s tube vs SS but both have their positives and a SS can have tube like characteristics which I like.

I’ve heard Mcintosh and liked it a lot but never heard this model.

I’ve never heard Sim but the reviews and comments about the 861 have been absolutely rhapsodic. And somebody whose opinion I trust said Sim is an excellent brand. But is this a flavor of the month model?

Has anybody heard both these amps. Any thoughts, opinions, advice?
