Since OP listens to classical music, I'll give you my one-track work which I always use for auditioning components (CD or streaming - I cannot afford the prices this record commands second-hand).
This work was originally recorded by Decca (London in the US) to analogue tape at the height of their skills in 1963. The recording has been available ever since on various media. The track lasts just over a quarter of an hour.
One serious critic has described the work as the best ever classical piece of music. It covers virtually every instrument in an orchestra, singly and together, has huge dynamic range, features complex percussion cross-rhythms and a finale where every section seems to do its own thing - something lesser systems cannot properly resolve.
It is Benjamin Britten conducting his "Young Person's Guide to the Orchestra"
