I recently got a Claro Halo XT for HTPC duties (movies mainly). I'm using a Harman Kardon Signature 2.1 power amplifier and Jamo C80 series speakers.
I want to roll some op-amps in it and I have some questions:
1) What's the voltage this card runs it's op-amps at?
2) I see there's an I/V and a buffer position on the HALO card and just three dual opamps on the XT daughter board. What do the op-amps on the daughter board do, I/V or Buffer?
2') If the do I/V, are those outputs buffered with another opamp/buffer? I want to run the same opamps/buffers on all channels if possible.
3) I noticed there are two buffer sockets, is one for the stereo out and one for headphones? If it is, it makes sense to use different buffers there ...
I was thinking about AD797BR on adapters for I/V (seems a safe choice) and for buffers I don't have any idea ... BUF634? Please specify if you actually tested the op-amp in this sound card if you recommend one ...
Thanks!
Here are some pictures with the card:
