Will a Proceed AMP handle LPCM input?

Could not find a definitive answer in the owners manual. If it won't there are lots of little black box adapters for $50 or less that will.

I looked in the owners manual for both the AVP/AVP2 and couldn't find a definitive thing either. Can you give me a lead on one of these little black box adapters? I am not familiar with them. Thank you.

I googled and found a little black box that converts LPCM into 2-channel analog. I want to keep the LPCM information in multi-channel. I guess I need to read up more on what LPCM really is.

I think I have found my answer out on the web:

Optical or Digital coax can only carry two channels of LPCM. HD Audio like LPCM will not pass over s/pdif (your optical connector). So if you want the benefits of that you will have to use HDMI to your receiver.

In other words, there is no way to get the HD audio format into an AVP.

I'll first confess that I don't really know what I'm talking about. But, as I understand it, I think that LCPM (linear pulse-code modulation) is simply a means, and a pretty standard means, of encoding digital information. It's used in CDs. It's used in DVDs. The DACs on the AVP clearly accept and can decode digital streams from both CDs and DVDs, so it can obviously handle LCPM. LCPM, however, can also encode up to what we might call high definition (i.e., bit depths and sample rates over the 16/44.4 that is the Redbook standard). LCPM is used in BluRay, for example. While the AVP will certainly decode certain multi-channel codecs – anything clocking in at what we might call more modern high-def sample rates or bit depths, or any of the more modern multi-channel codecs – none of them existed when the AVP was in production. So, it's virtually certain that they will not be supported. Thus, I suspect LCPM or no is not the determinative question. The question will be what you're encoding by those means. Make any sense?
