I'm wanting to get an audio interface so im looking for opinions on the best ones. i dont need a million in's and out's but i want a reasonable amount. In a big name studio what brands do they use? i want the best quality i can possibly get. It has to work with a PC. Suggestions would be great.

Big name studios use Protools. 
lol !


RME makes very nice interfaces with rock solid drivers and excellent support.

RME
Roland Capture series
MOTU
Presonus

You just have to do the research and find what will be best for you.

I use one of these, not a huge studio, but the results are fantastic. 
Focusrite Liquid Saffire 56   

For private use, 2 inputs is the norm. The choice is huge. Rolands QuadCapture is popular and gives good results.

If you need more inputs, you will have to be more specific. Also on how much you are prepared to spend. Adat bus expandable equipment like RME is in a different price category.

Or you could look at Tascam. They are very good and have an interface available for nearly every number of inputs going up in twos from 2 to 14.

My general observations of "Big Name Studios" is that they almost never use a PC for audio. Most of them are using Mac dual/quad xeons, esoteric HD3 systems, 2 inch tape, and lots of Pro Tools. Many of them use the converters in their SSL, AMEK, MCI, or whatever in their $500k mixing boards. Quite a few use modified systems with upgraded conversion by Burl, Apogee, Lynx, Prism, ETC... .
 
Most everything named so far is just not in the same league.  I am not dissing anything as I use a PC and run both Sonar and Protools, but I have never heard of a "Big Name Studio"  that uses Sonar or PC's for primary audio tasks. I'm sure there may be an exception somewhere, but this has been my experience.,
 
Knowing this, I have tried to make my studio as "pro" as possible without breaking the bank.  Since my use is primarily for singer/songwriters, I don't need a ton of inputs.   The room you record in is everybit as important as the equipment.  I have a fairly nice room plus a dedicated vocal booth. Signal path is generally Neuman, Custom made U87 clones, Audio Technica, Shure... etc  into   a ADL700 dual channel tube pre, into a Lynx Hilo AD/DA converter that is interfaced with a V Studio 700 system. I use the JBL LSR monitor system and some old school NS10's for monitoring.  This is as close as I am gonna get! I'm not a big name studio but this signal chain is pretty good.
 
You might check out the UA Apollo as a interface. It works fine with Windows and has gotten rave reviews. There is also a new Prism interface that is a scaled down Orpheus.
 
The Focusrite system noted in a previous post is pretty nice and can be upgraded at Black Lion Audio for under $600 with some really sweet Burr Brown Converters.
 
YMMV...  The most critical component is the musical input and the song. That is what really separates  the "Big Name" Studios.  

RME Fireface UFX.

Dude Ivey,
     Yours is a very subjective question, however, almost impossible to advise without some idea what kind of budget you are dealing with.  Can you give some kind of idea what kind of dollars you're looking to spend? 

Best,

Thanks for the suggestions. I think the RME Fireface UC might be what im looking for.

I think the most i could spend would be around 2500.00. Ive seen a few comments on the RME stuff so thats what im reading up on now.
