This one looks perfect, but it's really pricy

Opinions?
 
I think I'm most likely to buy the Behringer.

I've been thinking about the Behringer, and I believe it's a very good optinon if you think about the price. But I don't think I like the design with the inputs on the front. It will make a mess in the rack when all micpres are connected.
The audient unit looks very nice.....

Not sure what your needs are nor what your looking to do but this falls in the middle. I've been very pleased with it. Haven't had it connected to my desktop but it has worked flawlessly with my laptop for recording and live as an 8 channel mixer from my iPad to control the built in DSP (sweet). I also have the older version of the Behringer with BlackLion Audio Mod using it as an additional 8 channels via ADAT.

I found myself a 2nd hand Focusrite Octopre Platinum. Bit long in the tooth but the pre's are great, it does 96khz which the Behringer unit does not and it has a switchable bit of compression going in if wanted.

I've had RME gear for a while now but for a change of flavour on a vocal I'll sometimes use one of the Octopre inputs for a change.

I'm GASsing for the Audient, but I have the older Behringer ADA8000, and can't really complain! The new 8200 has basically identical features, but sligthly better specs

It's always hard to tell what you'll be able to hear.
 
As a programmer, I know I get a lot of credit for being able to implement other people's awesome tools. I think the same can be true in the studio. Listeners can't tell what part of the awesome is your gear and what part is you.
 
So, if I can buy my way into better, I like to. I can hear the difference between my old M-Audio FastTrack Ultra and my RME UCX.
 
I hate spending money for something I will not keep. I don't expect to be able to unload it used; I almost never unload used gear except as gifts. So buying something I'll still want next year is important to me.
 
@Mudgel, Speaking of RME... what's all the MADI stuff about? Does anyone use MADI who can explain the use case? I'm not sure I understand why it would be useful in a small studio, but I'm probably being unimaginative. I don't really know how all the parts work together in a cool MADI implementation.
 
I like the audient that I linked to above.

• adjustable high pass filters - useful for live sound, which I do.
• the ability to bypass the Pre's and just use the DAC by coming in on the D-Sub (I'd be surprised if it ever gets used this way.)
• The input Z control is not something I've seen on many Pres. It looks like it could be useful, if I don't set it badly out of ignorance. Is it safe to just set it high all the time? I don't know.
• Pad, phase and channel specific phantom are pretty standard at this price range.
• ** It does not have a computer controlled auto-level/gain reduction mechanism to help keep levels set in an appropriate range. **
  • Because it doesn't auto-level, how bad a clip sounds is really important information. When the RME Clips I can't even tell. It's just hard limited.
