Dorian was a top-notch, audiophile oriented recording company back in the 90s and early 2000s. They made a lot of recordings in the Troy Music Hall, a superb acoustic. I have quite a few of their recordings. If you like early music, The Baltimore Consort made a number of recordings on the label, they are uniformly excellent, as are lute songs with Ronn McFarlane and Julianne Baird. Jean Guillou made quite a few organ recordings for them, a bit eccentric but well-recorded with prodigious bass (one with the Dallas Symphony is worth getting for the Jongen piece in it). There are also the Kubalek recordings newbee mentions (I too like the Brahms recordings), and a number of chamber and orchestral groups that are high quality, both recordings and performances. Newbee is right, try the music that would appeal to you, I think you'll find it worthwhile. I'm listening to the Baltimore Consort right now, and the CD sounds as good as ever.
