They support the same basic capabilities as DVD-Audio (indeed TrueHD is the MLP packing format as found on DVD-Audio, extended to support 8 channels).
However, films are generally mixed at lower resolution than music, so it won't be the case that you routinely get 96kHz 24-bit recordings, like you do on DVD-Audio.
If you want to handle all these formats, I'd recommend looking for a player/receiver pair that has an appropriate digital interconnect. The main stumbling block is SACD, which still can't be carried digitally by a lot of kit. Your main options are:
- An HDMI 1.2 player + receiver pair supporting SACD; unfortunately no players yet available, but receivers are available from Marantz, Yamaha and Pioneer.
- An HDMI 1.1 player + receiver pair, with a player that converts SACD to PCM; players available from Oppo, Arcam and the Sony PlayStation 3.
- An i.Link player + receiver pair. Pioneer are the cheapest option here, both for players and receivers.
- A same-brand player + receiver pair with a proprietary interconnect. Denon Link is the most common.
Alternatively, you can always use multi-channel analogue interconnects. If you're not concerned about SACD, then HDMI 1.1 will do the job for all the rest.
I'm considering either:
a) Denon DVD-2930/3930 + Denon AVR-3806; or
b) Pioneer DV-989AVi (DV-79AVi) + Pioneer VSX-AX4ASi (VSX-84TXSi)
That will do the job for SD and the music formats; and both receivers will support TrueHD etc via HDMI from an HD player.
