I agree completely! No one can afford to own every recording. You have to choose how you want to spend your money. For me, I begin with the performance and how the conductor organizes his orchestra. I rely on reviews, especially over at HRAudio.Net. I tag all my music files with extra information. First, the venue. For instance, the Barbican in London is notorious for poor acoustics. Next, I look at the Sound Engineering team. Soundmirror from Boston does most of Reference Recordings engineering. They are superb! Finally, I listen to the music several times and assign a star rating (5 stars is best). Most on line vendors, like Native DSD, allow me to sample tracks.
I recently signed up for Amazon HD music. It's a bit tricky to set it up for full HiRez sound (24/192). But, it can be done. Most all albums I am interested in, especially jazz & blues, I can find and play.
Can't wait to find out how well the X3s play my library of music.
