High Resolution PCM Audio

Recently purchased a TriVista 21 DAC. The TriVista can handle 96 khZ 24-bit data. I know some music is available in that format but do not remember who produces those discs. Also wondering if the stereo track on DVD-Audio disc is PCM or MLP format. Any input would be appreciated. Thinking of getting a DVD transport rather than a CD transport if there is enough music to warrant it. I listen to mostly classical music.
There is hardly any music available in 96/24. I went to acousticsounds.com and brought up the site map and found a grand total of 24 discs in DVD24/96 or HDAD24/96. Don't sacrifice redbook quality for a transport that is capable of playing these 24 discs.
