Music for setting up speakers

cant believe audiphile who spends thousands on their system, havent understood or been explained clearly that the way to setup a speaker in a room is with a mic and careful measuring.

Magenta haze > pink noise.

                       "Maybe music where instruments are easily located, etc."

      The OP is clearly interested in accurate sound staging and imaging, as (at least) one goal of their set-up (considered two, by some).

      While one can use test instruments, to measure and balance SPLs and correct frequency response aberrations; they can't replace the human ear, when it comes to ambience recovery and voice placement (whether instrument or vocal).   What, exactly, would you measure, pray tell?

       The scientifically designed tests and Chesky CD I mentioned, were created to allow one to use their ears and eliminate any variables, from their listening trials.

What chamber music do you refer to, im using Tidal to listen and if i like i’ll hunt down the album eventually. My system by design is set, but product shipping has been an issue, everything in time.....I’m really looking forward to the combined sound of all my pieces, this is exciting.

i like the music suggestions so far, thanx

Btw solo vocalist is another suggested source, who do you like.

Thanx for the Chesky referal!!

Dear @kgveteran  : The @rodman99999  and the @murphythecat  are very good advises different but very good ones.

I agree that our ears/brain " knows a lot " but measures can tell us what in reality is happening down there even if we like what we are hearing.

About solo acoustic instrument piano is eassential and gives you excellent idea of what you are looking for.

Regards and enjoy the MUSIC NOT DISTORTIONS,
