The quality of the converters have motivated my choice, just above the beautiful cards RME as stable as it happiness.
I use it for the composition and decision-computer music voice it makes me change my old card M-Audio ProFire 610 and my tascam fw1884, the dynamic has nothing to do.
My config a i7 12GB of ram 1TB SATA2 HD 64GB SSD for the system and Windows Seven RC. I used it on my old athlon x2 6000 + and xp for months.
It works regardless of the system.

UTILIZATION

Installing xp nickel as a by seven.
Encountered no compatibility, the manual is no need y'en, cons by the management software of the card is used it must be complex, but hey it's not an amateur card and the game worth the candle.

GETTING STARTED

The drivers are super stable, I do not know if they are updated often, but why updater something that works perfectly?
I use it with Cubase 5 and full of plug (vienna, eastwest etc ...)
I get a latency of 6 ms with 200 runs good but it's a hyperthreading the i7 that cubase does not handle the moment with my athlon I went down to 2.4 ms latency.
In short I would not change his card for many years apart if one day I have the money to buy a Lynx Aurora.

OVERALL OPINION

I use it for 6 months, what I like best: everything! minimum: nothing!
Models I've had lots and nothing comparable.
Given its sound quality is normal price.
With the experience I Refer this choice without hesitate!
