Hi just got my HD-E1, extremely pleased, just as good as I'd hoped it would be. I'm currently listening through optical to 1.5mb DTS and it sounds just fine to me. Thinking about the future however I may wish to experience these new sound formats, and I understand that the only option with the HD-E1 is to let the player decode the signal and output it via HDMI to an amplifier that can accept linear PCM via HDMI. I understand that other options to utilise these new sound formats are to output via 5.1 analogue outputs as is an option on the HD-XE1, or to output via HDMI 1.3 (again, like on the HD-XE1) into an amp that can decode these sound formats (no such amps yet available I understand?). I obviously would only have the first option available to me, but I was just wondering whether any of these 3 methods is inherantly better than the others? I can sort of remember reading something about a 'jitter' that can affect sound signals sent through HDMI, can anybody enlighten me on this? One last thing, to save me researching this for about the next month, can anybody offer a rough guide as to how much I would expect to spend on a reasonable amp that can accept linear PCM via HDMI? Is it worth getting a 7.1 amp? And what is a benchmark figure for a good set of speakers? Thank y'all!!!
