dynamic classical which isn't boring?

Boring? I'd look at using iso/absorb stuff or better rez components to assure musical interest rather than bombast.
For example a euance platform will "tighten up" a cheap CDP so well that you'll be on the edge of your seat THROUGHOUT the Zander Starinski Sacre de Printemps on Pickwick (Jordan Hall live, 1990). Still my favorite disc. The reprise last year wasn't as good (but the same guy yelled his now-famous "gasp" at the end!).

Check out Sibelius Lemminkinnen Suites, the 4 Legends. If you find that "boring"..????

Here are my recommendations; hope you find it of some help.

Tchaikovksy Symphony #4 - LSO/Szell(conductor) on Penguin Classics

Vivaldi Four Seasons Europa Galante/Fabio Biondi soloist on Opus 111

Beethoven Symphonies #5 & 7 - VPO/Kleiber (conductor) on DG

Obviously there are many performances you can choose from for each piece, but these are my favorites and each of the performances definitely qualify as dynamic classical which isn't boring (there are some amazingly insipid performances of these released on major labels by major artists; it's a good idea to get a recommendation for any classical music piece you are interested in).

Edgar Varese's Ionization! A favorite of Frank Zappa!
