Auzentech X-FI Prelude 7.1 Sound Card

A Closer Look

A Closer Look

Well after a considerably long wait, we finally get a chance to have a look at the Auzen X-Fi Prelude 7.1 up close and personal.

To say that the Auzen X-Fi Prelude 7.1 looks a little 'busy' would be an understatement. The brown PCB is a little 'different', especially compared to Creative's black version. Personally I prefer black, but hey!

Auzentech has utilised every bit of the available real-estate on the PCB, where Creative's offering looks decidedly more sparse. Not that it has any effect on performance, but the Prelude's 'busy' appearance makes you feel like you are getting a lot more for your dollar.

The beauty of the Auzen X-Fi Prelude's design layout is well illustrated.

One particular area that is testament to Auzentech's build quality is the inclusion of solid capacitors. Increasingly we are seeing solid capacitor usage become the 'norm', particularly from motherboard manufacturers. Solid capacitors offer much higher quality and better reliability when compared to their electrolytic counterparts. Solid capacitors also have a higher tolerance for higher temperatures and they also perform better with higher frequencies and higher current than electrolytic capacitors. The Auzen X-FI Prelude 7.1 soundcard is certainly designed to last, and give trouble-free audio pleasure for many years to come.

Connectivity options for the Auzen X-Fi Prelude are plentiful. Featuring two inputs (line-level and microphone), four analog outputs, and optical connectivity...there should be enough options here for even the most discerning audio-enthusiasts.

On the flip-side of the card, Auzentech has kindly included identification for the inputs and outputs.

I have taken the liberty of highlighting some of the major components of the Auzen X-Fi Prelude below, and given you a brief explanation of their function.

National LM4562NA High Performance Audio OPAMP
The LM4562 from the NATIONAL combines extremely low voltage noise density (2.7nV/ √ ^Hz) with vanishingly low THD+N (0.00003%) to satisfy demanding audiophiles. The really cool feature here is that the OPAMP's are able to be changed. Don't like the NATIONAL LM4562! Then simply swap it out for one that is more to your taste. Excellent feature Auzentech!

Replaceable OPAMP

The Auzen X-Fi Prelude features 64MBb (2 x 32Mb IC's) of Micron RAM for audio processing; the Creative X-Fi features 1 x 64Mb IC. The RAM is intended to take a load off the CPU when processing and we should see a slight increase in frames/ second when running our benchmarks. Ah, we now have the absolute attention of the gamers amongst us...

Auzen X-Fi Micron RAM

The AK5394A is a 24bit, 96kHz sampling 2ch A/D Converter for professional digital audio systems. The modulator uses the new advanced multi-bit architecture and achieves 123dB dynamic range and wide bandwidth with superior distortion characteristics.


I can't help but reiterate just how impressive the Auzen X-Fi Prelude looks. The inclusion of 'top quality' components and the total layout of the card itself, sets it apart from the competition in my opinion. But the 'proof is in the pudding' and I guess we'll have to wait and see.

Now that we've had a look at the Auzen X-Fi Prelude 7.1 sound card in a little more detail, let's head over the page and see how the installation process went, and what the included software offers...

Wow, Nice review PV!

Looks to be a solid card.Quote

Looks like a decent card, if only they didn't have to use Creative drivers tbhQuote

i can certainly vouch for it i have one and i love it everything about it just 'feels' better than the other x-fi i had

would love a THX console for calibrating my speakers though but that aside i absolutely love it Quote

Seeing as it`s software is creative hybrid, I wonder if u can use the THX console that creative have on their cds ?

For me, these cards are equivilant to how an nVidia reference card gets adopted by other manufs.

Talking about the population of a creative card in comparison to this one, it`s also fair to bare in mind that out of the 5 or 6 creative x-fi cards that have been/are available, ranging from the cheapest to the professional studio ones, the density of the surface mounting goes from sparce to crazy-mad-caps-per-inch.

I would have liked to have seen a "crackle-test" on this card too, creative cards get easily bogged down fighting for internal bus usage (so it would appear but not confirmed) which makes them crackle. It`s a mad test to emulate, and it`s conditions are not 100% duplicate-able. But if u have a pc thrash at something like fah on all cores, do some rar`ing, do some massive file transfers..... and play some music - u get crackle on a creative x-fi. Maybe this is more a blame of the mobo design, or windows design, but it would be interesting.

Also - I want pci-e in this crazy lacking pci slot world !Quote

Creative just dont support THX in Vista, they suck

Crackle test - would have been interesting you're right

And yep, lets hope some PCI-e versions get out real soonQuote
