yyz,
As ricevs suggested, I'll chime in with a wonderful CD I just acquired, and have been using on repeat for my last 187 hours of break in listening. It is a 2015 recording on a budget label, Naxos, of Mozart Violin Concertos 3,4,5 with soloist Henning Kraggerud and the Norwegian Chamber Orchestra. It is a very clear recording which is upfront but also spacious. What is especially interesting is that there is a YT video of the same performers in the same hall. You can see the position of the musicians on stage in the YT video and compare to the CD on your audio system. The violin soloist has exceptional precision of bow technique, and the small orchestra is very sensitive and also brilliant. For proper audio reproduction of this music and recording, CLARITY is a must, and the most important criterion to use. On a musical level, Mozart is the most difficult composer to play, not because it is so complex, but because supreme elegance and attention to detail are required. The slightest flaw in technique is exposed, but this performance is close to 100% flawless. It is also improvisatory, and I am surprised that I am still enjoying it as a fresh experience after all these 187 hours of repeats, lol.
