    I currently have a Denon avr 3805 and have now got a PS3.

    I'm running the picture via Component through the amp to a projector, but was wondering instead of spendig loads of dosh on a new amp, can I not just buy a cheap and cheerful decoder that will input hdmi and output 7.1 discreet channels that I can plug into the external 7.1 inputs on my denon?

    I'm mainly after decoding the lossless 7.1 pcm channels, but if there's one fairly cheap that may do DTS-MA and the other lossless dolby codecs, that would be even better.

    Now that, my friend, is what I'm talking about!

    There are no HDMI inputs on my receiver but 6 chan input's a go go. I'd never considered such a device but would be interested to hear how others have got along with one. Just done a quick google but came up dry. If the mythical beast exists it could be a good value upgrade.

    I don't think such a device exists, but I personally think there is a market for such a device. Maybe combined with a HDMI switch, so something like...

    3 x HDMI in
    1 x HDMI out (or maybe 2 and make it a 3x2 HDMI matrix switch)
    7.1 analogue output
    Firmware upgradeable

    And on a per input basis have:
    EQ adjustment
    Audio delay
    Levels adjustment

    Time will tell if such a device is ever made. Hmm...

    A company called Zektor in the US has been working on a 7.1 switching device which is rumoured to also include HDMI switching. I'm not sure when they're going to release this product. It's been called the Zektor MAS7.1 . People have seen demos of it at CEDIA, etc.

    Check out http://www.zektor.com

    Edit: Found the link to the MAS7.1 : http://www.zektor.com/mas71/index.html

    Yes, but it doesn't "convert" HDMI PCM audio to the analogue output.

    True, but if it did, it would be perfect. Then there would be no need to upgrade your receiver / surround sound processor. I don't see a manual for this product as it's probably in final stages of development.

    I was reading up a very good review of the Toshiba HD-XA2 HD-DVD player by Audio Video Revolution and came across this very interesting bit of information. From page 1:

    And even further, from page 2:

    If this does what the review states it does, i.e. it can output the hi-def audio tracks via the coaxial or optical outputs, then that would be a better alternative than the Zektor MAS7.1 . For those interested in reading the review, here it is:

    For further information on the HDMI switcher:
    PureLink HS-42A

    If the Purelink HS-42A does what is states it does, then there is no need to buy a new receiver / surround sound processor for a long time.

    I too would be interested in a product like this. However, the Purelink item you link to there seems only to have HDMI in and out plus digital. It doesn't "strip out" the audio into what I assumed was a set of phono connectors?

    You're right, but it does strip the audio out and keeps it in the digital domain. If you have an extra coaxial or optical input on your receiver or surround sound processor, then it shouldn't be a problem.

    But optical and coaxial do not carry HD audio signals. This product linked to is little more than an HDMI switcher - the item described is a quite different thing.

    But the player XA2 or whatever will give you a digital output.

    Don't see the point in this function really, what we need is HDMI in and analogue phono/RCA's out. This is the only way to get HD audio formats in their full glory into a "legacy" receiver.

    I can understand your sceptism, but I have this sneaking suspicion that this switcher really can strip out the HD audio and pass it via the coaxial or digital outputs.

    Firstly, I didn't think you could get HD audio of any variety through coax or optical - I'm happy to be corrected though.

    Second, even if you could, in this scenario you would still need a processor that can decode HD audio, which rather defeats the object! What I would be looking for, as I believe the OP is hinting at, is a box of tricks that accepts HDMI inputs, then outputs the HD audio via phono outputs.

    I'm sure you will end up with standard Dolby Digital/DTS.
    HD audio, DVD audio and SACD can not be carried from player to processor via digital coax or optical.
