Auzentech Prelude 7.1 (Source: Hardware Canucks)
EAX 5.0 and Dolby Digital Live on a single PCI sound card

Auzentech is set to release the first third-party Creative Labs X-Fi based sound card – the Prelude 7.1. The Prelude 7.1, announced last month, allows users to enjoy multi-channel EAX 5.0 positional audio without connecting four sets of audio cables. Auzentech licenses Dolby Digital Live multi-channel audio encoding technology to provide users single-cable convenience over S/PDIF.

The new Prelude 7.1 mates features previously found on the Auzentech X-Meridian with the Creative Labs X-Fi sound processor. Auzentech equips the Prelude 7.1 with a removable OPAmp on the front channels output of the sound card, unlike the X-Meridian’s four removable OPAmps. A LM4562NA is the default installed OPAmp on the Prelude 7.1.  

Auzentech pairs the Creative Labs X-Fi sound processor with two memory chips for 64MB of memory. AKM digital-to-analog convertors are installed on all eight audio channels, a step up from the Cirrus Logic DACs employed by Creative Labs. Other notable features of the Prelude 7.1 include audio headers, although it is unknown if they meet Creative Labs’ specifications.

Expect the Auzentech Prelude 7.1 to trickle into retail channels in the coming weeks.

Opamps

The LM4562 is a very very good opamp and does have specs equal to and sometimes better than the OPA2134 (recommended upgrade op amp for the Meridian). Some have upgraded Creative X-Fi cards usually using the LM4562 as the drop in opamp to replace the less than stellar opamps provided by Creative.

I have an X-Fi Platinum and notice the multi pin connector at the top of the Prelude looks identical to the Platinum, so if the pin connectors are the same, front panels that came with the Platinum and ExtremeMusic might be usable with the Prelude.

I sure hope that's the case -- would actually convince me to special order this. :) I currently use an X-Fi Platinum, and could definitely appreciate even better sound quality.
