$5000 living room speakers for classical music

change the speakers and yes. Those speakers lack lower treble forwardness necessary to not sound less snappy, attack presence and dull edges whilst still being sibilant and harsh @joselijoseyang 

this is a better setup:

There are a pair of Vandersteen 5 speakers for sale here for 5K. I know nothing about them other than they are excellent Classical music speakers.  Even my long gone models 2 and 3 were fantastic on Classical. 

My KEF R7 Metas fit that bill perfectly, are clear, uncolored, and disburse well around the room not locked into a sweet spot. Should be an easy audition. Good luck on your adventure!

I have set of Klipsch IIIs for sale and here is how AI descibes setup with your miniDSP:

The miniDSP SHD Power (120W/ch) and Klipsch Heresy III speakers make an excellent, efficient pairing for classical music, leveraging Dirac Live room correction to manage the Heresy's unique, horn-loaded, high-sensitivity sound signature. The system offers detailed, dynamic, and spatially accurate playback ideal for orchestral works.
