Stereo or monoblocks

I forgot to mention what got me to this point. 
I’ve been using a Mac ma6600 integrated for the last 5. I’m completely happy with it. I’ve never had anything as good before. Never owned anything than old receivers before. However I’m going to separates now snd the C2300 checked all my boxes. Just looking for my power section now, trying to stay under $4500 budget. Thanks 

Thanks everyone, I really appreciate the input. I still haven’t decided yet, Im taking my time. I doubt I’d ever get to listen to them before purchasing. I like the mc402 because it’d match the c-2300. I could get one used around $4500. However it is big and heavy. Im very interested in the Schiit Tyr because of the great reviews I’ve seen so far. It’s also two smaller/lighter units which is easier to place in rack, plus I’m curious about the mono sound (imaging etc.). They’re also a little cheaper and brand new. I wish I could test them side by side. Once again think you all for your opinions……..keep ‘em coming.

Thanks for all the advice guys.
