I think the way you have described what your looking for,then in theory the CX-7 could do the job.
Of course I think it would be safer if you auditioned but I realise that may not be possible.
The Ayre is smooth but natural sounding and I think very good with all types of music, it really just really gives you whats on the disc -there are not many who've heard it been able to pick out obvious weaknesses in it's sound-it shouldn't add to the brightness but it is a very detailed player.
I do think to some extent though your speakers imho sound like a bit of a problem-I think you could easily get it wrong or the synergy of what you pick in reality might not match the reviews or opinions you've been given.
Let us know how you get on.
