Lets have a close look at the Hardware sections:

Multi Channel Speaker Output

The Bravura 7.1 has milled opamp sockets and 4 replaceable opamps for the line outputs/speaker outs. In the picture we can see the high quality Nichon Muse ES capacitors for coupling the outputs and high grade metalized film for opamp filtering.

Headphone Output Circuitry

The headphone output is using Auzentech proprietary designed circuit and is separate from the cards line outs. We can see the Wima film audio grade capacitors and the upgradeable opamp in a milled socket. The headphone output supports a maximum sampling rate of 24/192 KHz output.

Power design

The Bravura 7.1 uses an upgraded power filtering design.

The new design employs conductive polymer capacitors. Which have an ESR (Equivalent Series Resistance) rating of 10 times lower over generic filtering capacitors. As a result of this improved circuitry design, the Bravura 7.1 has an exceptional instant power supply capacity. Lets have a look at the Specifications:

Auzentech Cappuccino EX Sneak Peek
The audio market is constantly expanding and evolving with new products for the internal and external market places. We always do what we can to bring our readers the latest and greatest information on upcoming audio products for their audio systems. So without further delays, lets get to the good stuff shall we?

Auzentech X-Meridian 7.1 2G Preview
We have an exclusive sneak preview of the Auzentech X-Meridian 7.1 2G soundcard. This card also marks a move back to the highly popular 8788 based chipset (at least for this model) that has been seen on some of the best sounding cards built to date. This card has many of the original ideas that made the XM 7.1 so popular but also has some changes that will appeal to different user types. The card is also aimed at a lower price point with a MSRP of $159.99 which appeals to a larger audience.

Auzentech X-Fi Home Theater HD 7.1 Soundcard review
Auzentech has been developing an HDMI soundcard for quite a while and this new card is said to be loaded with features for any audio tasks. Today in the Guru3D audio lab, we have a brand spanking new Auzentech Home Theater HD 7.1. This ongoing one-upmanship between existing companies is what drives the soundcard market and ensures new products are higher quality and offers new and innovative features to the audio community. The HDMI standard is still considered new in the PC landscape, and while many GFX cards offer HDMI options for graphics the audio side of the standard has been ignored and is lacking. We are going to run this card through our extensive testing and measuring regimen to let our readers know exactly what you will be getting for your hard earned audio dollars.
