    hi
    could anyone assist, what i am looking for is how to improve the sound quality from my hcpc my set up at the moment is:

    pioneer dvd 106s rom (standard cable to sound card) multiregion

    creative sound blaster 5.1

    Win dvd version 3 with dts

    via spdf coaxial cable (van den hul) to Lexicon dc1 processor (version 4 upgrade with dts/ex output)

    I only use this set up for movies and not music could it be i need to change the cable from the dvd rom to the sound card or change both the sound card and the cable?can anyone suggest alternatives please?

    I have 1 dts music disc (police/ every breathe you take) it will not play on the dvd rom win dvd recognises it as a cd with dts output but it makes an unpleasant noise, also when the disc is put in the dvd player the cd player comes up first which i close it down and activate the win dvd player.Could anyone help or advise?


    many thanks

    richard

    If you have a Lexicon then you should get the MAudio DIO 24/96 card for about £150. It makes a big difference to audio quality.
    Check out the sticky thread at the top of this forum for more info.

    I use reclocking boxes between the digital otput of my HCPC before feeding to the AV32R. Digital quality from HCPC is really poor, loaded with jitter.

    Hello Nic,

    What sound card are you using that has really bad jitter?

    Thanks,

    Mark.

    Jeff,

    You might find this an interesting read.

    Here is a Google search with some good reviews and links to the Dragon 5.1

    Do a search for M-Audio, there are lots of comments and places to purchase from.
    The M-Audio is definately the way to go.

    ok thank you everyone

    can anyone give me the exact model number for this card there seems to be a few of a similar name ie is it the

    M-Audio delta audiophile pci or the M-Audio D10 24/96

    just don't want to order the wrong one

    and finally as previously mentioned am i defeating the object by replacing the sound card if i don't change that standard cable between the dvd rom and the sound card + the dragon 5.1 reads very well if not a bit expensive.

    thanks

    richard

    No, the cable between the dvd-drive and the sound card will not be needed (I don't think the M-audio even has a socket for it).
    So no worries there.
    The signals pass through the PCI bus.

    Richard,

    Most people are buying the Audiophile, you should find it for £150 delivered, it is usually cheaper than the Dio.

    The Dio has Optical and coax SPDIF output + analogue(I think)

    The Audiophile has Coax only + analogue, and is all you should need for quality HCPC/HTPC audio output.

    Mark.

    I use a 'Nic Rhodes' special for reclocking but the Camelot one is just what I am talking about. HCPC are LOADED with jitter, even the best cards discussed here. Re clocking boxes are widely available but make sure you ask if they ca do DD / DTS, many of the older ones only do PCM 16/48.

    For devices that out put DD/DTS Digital signals, it is only the likes of the Tag / Theta that can't be improved with them (actually worse). As the above link shows even the posh Toshiba can.

    One word of warning about the Audiophile, it appears from a number of threads on AVS that XP compatibility isn't one of its strong points. Just something to bare in mind in case you are heading in that direction. The Terratec also has problems with its latest driver 5.0.2000.116, but the 115 revision that comes with the new DMX 6 Fire 24/96 is fine.

    Nic, any suppliers of such devices in the UK? Importing is such a pain.

    Thanks,

    ok just about to buy the M-Audiophile sound card but im i right in thinking that it is only a 2 channel card not 5 channel like the sb 5.1 i have at the moment? would i have to use the spdif via mini jack then coaxial cable to the lexicon dc1 and let the lex do the spliting?

    Also a hi-tech music shop in leeds (who actually made me aware it was 2 channel when asking what i was using it for) suggested another card the M-Audio delta 410 which is more for home cinema use any one got any thoughts

    cheers

    If you're just taking a digital signal to an amp it will make no difference.
    The more expensive m-audio card does the decoding for you but it will probably be worse than your amp. I've a feeling you don't even have control over the volume for each channel using the delta 410!
    Just connect it as you described (same as sb5.1)

    The 5.1 on the SB is a completely different thing - It has no benefit for HC use. It is just for games. If you want your games to reltime encode DD5.1 and output it to your amp then the m-audio cards will not do.

    Hope this helps

    The M-Audio uses phono connectors, so you will need a phono to phono coaxial cable. Good decision by the way.

    fatrich,

    If you want to keep Lexicon as a part of your system than most convenient way is to connect sound card’s SPDIF out to SPDIF in of Lexicon and let Lexicon decode digital stream into what ever number of channels you instruct it to do. For this scenario you can use any of the following M-Audio cards: Delta Dio 24/96, Delta Audiphile, Delta Dio 1010, Delta 410.

    If your intention is to decode AC3/DTS within HTPC then in order to output 6 channels simultaneously you will need to an audio card with at least 6 (analogue) channels, e.g. Delta 410, Delta 1010LT, or Delta 1010. This scenario has some inconveniences associated with it but pound-for-pound offers significant audio improvements. Please note than multi channel sounds do not decode themselves, but only provide digital-to-analogue conversion of Wave audio streams generated by the decoding application (e.g. PowerDVD, WinDVD, CinePlayer or similar).

    In my 1st HTPC (running Windows 2000) I use Delta Dio 24/96 connected via SPDIF to Yamaha DSP-A1 that does decoding, amplification is done by Bryston that is driving set of M&K S-150 speakers. This works nicely and I consider Yamaha to be the weakest link and my next upgrade target.

    Another HTPC is WinXP based and uses Delta 410 directly connected to 6 active Genelec speakers + 3 subwoofers. This is money wise cheaper than the first setup but sound is way beyond what I expected when putting it together. However, controlling everything via PC is still very crude, but when it works it is pure joy.

    Note that Delta 410 and Delta 1010LT are the only models that will have software controllable volume on all channels + some form of bass management and room positioning capability built into the driver.

    Other Delta cards allow volume control on the main two channels only.

    I am still no sure what exactly you are trying to achieve, but if you buy Delta 410 than all options are open to you. Few months ago I notice that www.turnkey.uk.com had Delta Audiophile cards for £120 (inc VAT). Delta 410 should be less than £200.

    Good luck.
