System forclassical music


Some friends are looking to upgrade their home stereo system from something that is probably 30 years old with in-wall speakers wired throughout their house.  They are classical music buffs, which makes me leery of giving them much advice (I prefer rock, female jazz vocalists and Argentine tango).  They are discerning listeners, but probably because of their current system their expectations were low - they really didn't think that a home system could come anywhere close to a concert hall experience until I streamed Chapotier's Te Deum from Qobuz on my (modest) system and their eyebrows went up.  I told them that they could reasonably do even better, but I really wouldn't know what to advise them.  I realized that I actually don't know a dealer I would trust sending them to!  Sad, but true.

So let's say a budget of $5 to $10K for a core system (streamer, DAC, amps, sub, speakers - TT and CD transport to be added later).  Integrated is fine.  Assume a 15x20 multi-purpose room (I alerted them to room correction, but first things first).  Any suggestions as to what might be a good fit for them?  Thanks.

Yes, I did mean Charpontier.  As is obvious, I'm not a CM fan.
I don't know the preferred source yet; I just assumed it would be streaming.
I doubt that they want in--wall speakers in a new system.  It just what they have now.
I didn't know that SACD was big for the CM world.  Thanks for alerting me to that.
Any dealers all of you can point us to in Chicago?  Thanks.
If you are willing to drive to Milwaukee...  Audio Emporium.  The guys are awesome.  Very down to earth and trustworthy.

How willing are they to deal with separates?  with tubes?  They might be better off with something like the NAD M10 or M33 (both of which have a streamer, DAC and room correction) and speakers they like.  There is a lot of classical music available streaming (Primephonic and Idagio are almost exclusively classical) so this would seem to work easily and well.  
treepmeyer,  do they currently have in-wall speakers?  or are looking to use only in-wall speakers?   A pair of Magnepan on walls may work for their main listening space.
