I'd be interested to hear such a combination. I did have some Cyrus components for a brief (!) period which I would pass on to be honest!
The BeoLab 9s don't exactly have a forward midband. Some people find they lack mids, but when set-up correctly, they sound stunning. I'd maybe look to go for something which complements, but contrasts this sound slightly. Something like a Naim 202 - very musical and lively, but with a big in-your-face midrange.
The only Naim CD players I've listened to would be the CD555 and the CD5 XS, and both were part of systems which sounded great to be honest. I couldn't really comment on them much more than this as I was also listening through different amps both times...
That's just my 2 cents anyway. Ultimately, I'd try whatever to try and demo your combination, but I'd say Naim with BeoLab 9s is a safer bet IMO. Bear in mind I haven't actually heard this combination so maybe I shouldn't comment at all!
