pbb, in my experience posting my opinion of the best of anything when no one has inquired regarding a specific recording is a waste of time and bandwidth. when some one wants a specific piece they can post and i'll bet they get a good response. for example, on your bartok, concerto for orchestra, i would recommend fischer and the budapest festival orchestra on phillips or reiner and the cso on rca. if all you want is the best recordings just buy whatever you want in the basic repertoire from reference recordings, dorian, delos, chandos, bis, hyperion, telarc etc. i think you will find that most people who are seriously interested in music are interested in the quality of the performance not the quality of the recording (which if good is a plus). this is probably why you get such a limited response (IMHO).
