Question: Has anyone experienced any issues in regards to conflicts with any video cards? I have a Sapphire AMD Radeon HD 6850 PCI-E Card.
Document: The quality of the audio output from this card blows the doors off of the Realtek onboard sound chips appearing on so many motherboards nowadays. Paired this card with a Sennheiser 150 Ohm headset and I'm in heaven. When gaming I can hear even the smallest nuances around my character in clear detail, it's incredible! The driver install provides an app that has more DSP, mixer and configuration options than I will ever use.This is a PCI card, so be sure you have a PCI (not a PCI-E) slot available.The capacitors are rather tall and can possibly make contact with a card installed below it, especially if the card below it has chips on its backside.Be sure to properly set the jumpers for the impedance level of your headset.
I hate adapters. Not only do adapters look messy and ugly, in this case it may also have an impedance and signal voltage mismatch problem. With this soundcard's dedicated RCA stereo connectors, it is total peace of mind.If you need to drive your front audio panel, this card has everything you need.The driver is perfect, showing no issues at all. Instead of using the driver that comes with the sound card, I directly downloaded the most up-to-date version and installed it. The control software is not very sophisticated.
I've purchased many sound cards over the years from different companies (Creative, Asus, etc. ), but this card blew me away. I use headphones exclusively and after rebooting my system after the driver install, I was blown away by the quality. I felt like I was in a professional sound studio.I can't describe the difference in sound quality between this card and everything else I've ever used in my life. It's a little expensive, but once you give it a listen, you'll know where the extra dollars went.
My wife and I noticed a big boost in electronic resonance and stage presence when we played You Tube music videos BUT NOT DVD MUSIC DISCS after installing the 770 video card. I surmised that the Haswell chip was trimming the frequency response and/bandwidth on the You Tube internet download. Additionally the native Realtek 898 was probably compressing or something UN-holy like that.Remaining was the ongoing lack of imaging control (after initial setup) over the 5.1 speaker stage and the ongoing inability to register DOLBY STUDIOS CONTENT on my home theater system.The OXYGEN audio processor on the HT OMEGA Claro Halo audio card wiped out all those nasty problems.
I highly recommend this card!
I have a set of AudioEngine A5 speakers and a Velodyne Impact sub hooked up to my computer. Together with this sound card, they easily rival my Marantz/Energy set-up for quality of sound. This was easy to install and the build quality is excellent.
Paradigm Shift A2 and Klipsch SW-308 sub. This Omega Claro feeds a 'Beautiful' signal . This new sound system is my dream . Just a delight to listen to from Led Zeppelin to Mozart and all in between. Bang for the buck !! This card has it imo . I truly enjoy it .
if you need sound pc sound quality this is the one you need for good. I don't really write on reviews but this is awesome sound card. I owned ASTRO a40 and other asus sounds and creative sound blast. but comparing with this is no way of challenge of other sound card to this date!
The noise scaled with the volume. This led me to research more about audio, and learned that it was an internal problem tied to the motherboard. I decided it was time to upgrade my sound system. I chose this brand I'd never heard of before simply because this sound card had a built in headphone amp.When compared to the on-board audio found in an Asus P8-Z68 V Pro there is a clear, noticeable difference in sound quality. It wasn't just the Denons that were improved, all of my other headphones had improved.
Soon to up-grade to some nicer monitors if i can only make up my mind .Seems there is a great choice of powered speakers now a days . I can only dream how nice it will sound when all is said and done .My old ears have not tried out yet and have been listening to music all day . Couldn't do that with the Realtek Audio Nvidia drivers MB SC..Simple install btw . Ht-Omega website told me how to setup the card for Win7 64 bit and it's been pure pleasure ever since ..Thanks to everyone for the fine reviews and tips .UPDATE :upgrade complete an burned in .
Answer: No , never an issue .  run a Nvidia GTX 460 . The HT omega has been stellar in all respects . Good luck
