    There is a very interesting discussion going on at AVSForum regarding the above issues.

    In short I have learnt that WinXP kmixer would for all properly written WDM sound card drivers effectively re-clock 44.1 kHz CD wave stream into the same 44.1 kHz, resulting in a similar but not identical bit stream. This action has audible effect on CD music reproduction and makes WinXP sound bad in comparison with Win98 where this is not implemented. It also completely prevents DTS CD’s from playing.

    With regard to DTS and AC3 from DVD's the situation is different as they are classed as data streams rather than audio streams and would therefore be let thru kmixer without modification.

    The threat also reveals that the only professional grade sound card to have their driver implemented to avoid kmixer interference is RME DIGI 96/8. The PRO or PAD version of this card has SPDIF as well as 2-channel output with stunning 112 db dynamic range (for comparison M-Audio Delta 1010 with extranal D/A converter has dynamic range of 108 db, Lexicon MC-12 has 111db).

    More interesting is that turnkey music shop in London just sold me this card for £270 inc VAT after invoking their 'Lowest Prices Guranteed within UK/Europe'.

    Happy reading everyone!

    Hi Branxx,

    That's a read-and-a-half ! :)

    I am looking for an audio card, and was wondering why you chose the RME 96/8 *PAD* and why not the RME 96/8 PST or RME 96/8 ?

    Do you know if these cards also have the low jitter performance of the PAD ?

    best regards,

    Paul.
