Auzentech X-Fi Prelude 7.1 (Source: Auzentech)
The first third-party X-Fi based sound card will have Dolby Digital Live and DTS:Interactive

Auzentech has posted detailed specifications of the upcoming X-Fi Prelude 7.1 sound card. The Auzentech X-Fi Prelude 7.1 is the first third party sound card based on the Creative Labs X-Fi sound processor.

Auzentech pairs the Creative Labs X-Fi CA20K audio processor with AKM digital-to-analog and analog-to-digital convertors. Auzentech employs four AKM AK4396VF DACs on X-Fi Prelude 7.1. The DACs boast 24-bit resolutions and 192 KHz sampling rates with a 120dB stereo signal-to-noise ratio. An AKM AK5394AVS ADC takes care of audio input duties. The ADC features 24-bit resolution and 192 KHz sampling rates.

The X-Fi Prelude 7.1 features a single user-replaceable front-channel OPAMP. Auzentech installs a National LM4562NA OPAMP with a rated 0.00003% total harmonic distortion levels on the X-Fi Prelude 7.1. The other six channels feature TI OPA2134 SoundPlus OPAMPs. The TI OPAMPs are not replaceable.

The new X-Fi Prelude 7.1 takes advantage of all X-Fi sound processor features including EAX Advanced HD 5.0, CMSS-3D, X-Fi Crystalizer and SoundFonts. Auzentech also installs 64MB of X-RAM on the X-Fi Prelude 7.1.

Eventually the Auzentech X-Fi Prelude 7.1 will feature multi-channel audio encoding technologies. Auzentech plans to add Dolby Digital Live support in Q4’2007 for Windows Vista and XP. DTS Interactive and DTS NEO:PC support is planned for Q1’2008 for Windows Vista and XP operating systems.

but please dont tell me creative is putting more expensive parts in their soundcards then most audio companies put in their receivers


I don't say Creative puts better stuff on their cards than receivers, they put codecs, but some receivers got codecs too. The only way to get "decent" Creative stuff is to get, like I said, the "high-end" cards (The most expensive X-Fi uses separate DACs)

Well, maybe I should have said $300 or $250 receiver instead of $400, I forgot that their price keeps going lower.

If you want amazing analogue sound that will blow your digital sound away, you will be paying many times more than a creative card will ever sell for.

I agree if we're talking about cassette or LP, but sound cards, even with the analog outputs are still a digital source. The DACs on the sound card are just at a greater distance from the power amps than the receiver's own are, that's what is supposed to make the analog outputs worse than a compressed 18-bit max signal through a single wire.

Knowing a lot of average CD players and receivers, playing a CD in DAE mode through a card like a C-Media based Auzentech would probably sound better than the receiver's own DAC.

However, a normal Creative card's output stage doesn't go much further than a motherboard audio with a bonus being a 7805 regulator and a capacitor filtering the power so we don't hear data streams in the sound.

I don't know any analog sound cards by the way...
