The Theatron Agrippa DTS 7.1 - which is an Auzentech HDA X-Plosion 7.1 DTS Connect - should be available tomorrow at the biggest etailers for a stunning € 69,- (included taxes) in Europe. While the card is $99.95 in U.S. this looks like a bargain for European customers.
The card is a real high-end model, featuring an all-solid-capacitor design and incredible AKM DAC and ADC's. Utilizing the C-Media CMI-8770 chipset which also supports real-time encoding of Dolby Digital and DTS streams.
If a customer wishes, the standard DAC and ADC's can be replaced with better ones, because they are all socketed, so replacement is easy, no soldering skills needed.
Of couse all the important connectors are available, analog outputs for 7.1, digital outputs in both flavours (optical and coaxial S/PDIF) and MIC-in.
