clssical piano music

Hello, I am the webmaster of http://greatpianomusic.com and I would like to start a discussion about the music found on that website. there is much freely stream able and down loadable unlike other websites that clain free music. also we own the copyright to everything there so we can do that legally and finally we are adding new tracks almost every night. our dilemma is: should we put up tracks which are not the greatest audio quality because they were recorded a long time ago on inferior equipment if the musical performance is A+ or not? we say yes. what do you say?
