by Rob Williams on August 15, 2005 in Audio & Media

Are you looking for a quality sound experience at a great price? We are looking at Chaintech’s AV-710 card, which is based on the proven Envy24 chipset. Does it have what it takes to compete with the big boys? Let’s check it out.

Page 1 – Introduction

When I was in the market for a new sound card, I immediately thought about buying an Audigy 2 ZS. To my surprise, friends kept telling me to get a Chaintech AV-710 instead, which costs less than half of what the Audigy does. So, I picked one up, played around with it for a week, and this review is what I thought of it as a whole. Here first, is a quick blurb about Chaintech.

Upon closer inspection of the card, we can see a lot of what the card has to offer. At the end of the card, we can see a Mic In, Line In, Line Out, Surround Out, Center/Bass, ALT Out and an S/PDIF Out. To the top right, we have the Aux In and CD In connectors.
