Scott,
If you really want to see expensive, look up the recordings of the Auryn Quartett and anyother recordings on the
TACET label. TACET specializes in dvd-a and sacd (non hybrid) and they charge enormous amounts for discs that hold tons of music. Interestingly, you can't rip any of it because they don't have a stereo layer so I don't buy it, despite the rave reviews of performances.
