It's all opinion, everything is on here. I've just heard lots of people not think roksan is great compared to some brands. I've heard it being quite hard hitting but not exactly nuanced and detailed. Would be different if you own it of course!
Cyrus might not be a match, but on one of my earlier posts please see what I said as I agree with you. It's really up to the original poster. I wouldn't really say if you were spending £5k of naim stuff that it's detailed like Cyrus is. I might not put Cyrus with Bx5 in stereo, but to inject more detail I might. I had the centre channel bx5 and it got a huge kick of detail with my cyrus stuff for the better, and centre channel clarity, when I ran it with an cyrus x power in mono once, instead of via a £1k onkyo home cinema amp I had.
