Winter Audio Reference: On-Board, Consumer, and Pro Solutions

Final Words

Intel HD audio quality isn't the highest in the industry for on-board design. This is fine for an average user, but if Intel is pushing on-board audio experience, they should make some enhancements to signal quality. Listening at higher volumes to quiet tracks could sometimes give the hint of a little noise that wasn't supposed to be there. Overall, the listening experience was very good for Intel's solution. And their audio enhancement software by Sonic Focus actually does a good job of delivering on its promises where all other software of a similar sort (that this reviewer has heard) falls short.

The SoundBlaster Audigy 2 isn't the best for straight audio listening. The card has IMD problems at the very often used 16-bit/44.1kHz setting (CD's, MP3's, games), which seems to produce a slight coloration of the audio. This doesn't matter as much (at all?) for movies and games, but for listening to CDs and music files, we would expect better. As a consumer card, where the target is for an entertainment systemm the Audigy 2 offers a good setup, especially when movies and gaming will be a central focus of the machine. For those who wish to dabble in recording, the Audigy 2 is certainly better than an on-board solution and offers 24-bit/96kHz recording of either analog or digital sources.

The Gina3g hits the numbers really well in some cases, but falls short in places where we'd rather see them do better. Our test would have looked better if we had an external balanced device to test against, as our loopback test created a ground loop. Listening to the Gina3g was a very clean experience, although setting up surround is interesting with the configurable ¼ inch outputs, and buying proper converters was interesting. The Gina3g is made more to be a cog in a machine than something to be listened to, but it does very well in a pinch. Of course, if the plan is to listen on the same machine as well as be used in recording, a separate audio card may be desired. The Gina3g can only maintain one sampling rate at a time and will alter all sampling rates to the most recently requested. In other words, if we're recording at 96kHz, and half way through, I double click a 44.1kHz audio track that plays on my Gina3g, half of my recording is going to sound really high pitced and fast when I play it back. This is avoidable if a separate audio card is used for playback while the Gina3g is recording (though, we would still recommend against doing this).

Interestingly, the Audigy 4 is a top performer in our tests, as the improved build quality serve to mask some of the issues that we've seen with the Audigy 2. We would still like to see balanced I/O, and truly reprogrammable sampling rates (to avoid the 44.1kHz resampling issue and IMD problems altogether). But overall, the Audigy 4 Pro is a welcome improvement to the Audigy 2 ZS Platinum Pro. Not so much that we would recommend upgrading, but if you have to choose between them, we would point in the direction of the Audigy 4.

But that is by no means a conclusion to audio here at AnandTech. The preceding was meant to cut a cross section through PC audio. We've touched on integrated solutions, consumer add-in products, and professional cards. In future audio reviews, we will be using the cards from this review as a reference point for other products in their respective categories. As audio makes a return to the pages of AnandTech, we hope to bring out reviews of products based from the likes of M-Audio, Terratec, EMU, RME, DigiDesign, MOTU, Lynx, C-Media, NVIDIA, Analog Devices, more Realtek, and anything else you can suggest to us. We will also try to include older cards (such as the SB Live! and Turtle Beach cards) for reference in future articles as well.
