Well, Chastity ran a udial test and the mighty Audigy4 failed. So the CS ASRC chip is prolly used only for input... Linky

1212m is the least colored, most detailed sound card I've heard. But I didn't hear that many, so YMMV. The usual complaint is that the 1212m is too analytical. Hearing that someone complains it's colored is a first.

Quote: Originally Posted by dallasstar No, I reread the review. Apparently, Creative told them that the card has crappy inputs, but the output is much better than Audigy 2. So maybe it's not that bad after all. The loopback method won't work with this Audigy. Crappy inputs make...

With all those CS4398 DACs, CS8420 ASRC and it's still bad? If they've "saved" on the clocking circuitry it would be truly stupid. Maybe the fokes at extremetech missed something, like a bad loopback cable. You won't hit the advertised measurements for 1212m with just any cable, so the same...

Wodgy, you are probably right. The nanophon paper I linked was about digital filters, yet nobody seems to have noticed. CosmoKramer, "faster" was a misquote of mine for lan's "more lively" (dam' it's the second time I do something that). Ask him what "more lively" means. I never listened...

Quote: Originally Posted by lan I don't think the 0404 sounds faster than 1212m/1820m to me. It sounds more lively and it's not in the treble where this less roll off is. Most people don't use >44.1khz so this isn't a deal breaker for me. I've never even suggested that ultrasonic...

Quote: Originally Posted by mikechai Hmm ICHI said the DA analog filter on 0404 was redesigned. Does that mean that 0404 was designed later than the 1212m/1820m ? Probably. The 0404 was released later.

Those 4 extra bits only exist in the HDCD marketing bullsh*t and in the wet dreams of the audiophools that buy it. Proof: HDCD AES paper. The HDCD simply has a control side channel encoded in the least significant bit of the 16 PCM bits. Only 1-5% of the samples are used for this. The control...

The HDCD AES paper is a great reading. It also touches the issue of building an electrically controlled switch box: "The switch box itself is composed of sealed rhodium relays in both the active signal leads and the grounds, with careful isolation of the control signals. The relay operation...

Breaking news: http://productionforums.com/emu/topic.asp?TOPIC_ID=1812 The DA analog fiter on 0404 hass less ultrasonic rolloff that 1212m/1820m. Interesting.

WMP can play HDCD, so this is no surprise. I'd like to see this feature in another player. Is there any other player that supports this?

Here's the original article from DAFX98 conference on the DSP core (called FX8010) included in the 10K1 chip. I suspect that most of the kx documentation was based on this paper.
