Hmm. Well I can only talk about the interfaces I already have. I wouldn't say any are audiophile but are definitely professional quality.
M-Audio mobile pre 2x2 USB
Headphone amp works with 250ohm DT880 but does not drive quite as high as I would like, but enough to mix without running into problems. It has the combination 1/4 XLR jacks that are great space savers. Picture an XLR input with a headphone jack in the very center so it takes either kind of input. It has seperate volume knobs for main out and headphone so you can have your monitor levels independent of your headphones.
It has a reasonably quiet pre-amp and provides phantom power. I have a Rode NT1a mic and they work perfectly together, plenty of sensitivity and no real noise to speak of. Maudio includes an ASIO driver on their webpage and it also works well with the ASIO for all driver.
I've used it on 2 different laptops and 2 different desktops and never ran into USB bus power issues or weird issues like sound cutting out etc. It wakes without issue when I put my computer to sleep.
The output is clean, trasnparent, and sounds great on my BX8 bi amped studio monitors.
If you are a guitar player though you might consider #2 in my equipment list
The Line 6 UX2 2x2 USB/Guitar input.
This is similar to the Maudio in feature list except it doesn't have the combination xlr 1/4 jacks but it has 2 dedicated guitar inputs, one normal, one pad for live pickups. The best part is that it comes with Line6's Podfarm 2 which emulates dozens of guitar pedals, amps, mics's, and makes the process of recording realistic guitar without micing an amp cabinet really convenient and easy. It is only $50 more than the m-audio and is a guitar players dream.
It includes 2 analog level meters that are lighted, has seperate headphone and monitor volume knobs, and it can drive 250 ohm headsets but not quite as loudly as the Maudio can. With a Sony MDR-V6 it can drive them to uncomfortable levels though.
It supports 24/44.1 in and out, is reasonably clean sounding and transparent and a little on the warm side.
I've only used it on my desktop and the only issue I've had is just in the last few days running at 24 44.1 it sometimes locks the audio driver when used with foobar2000 in waspi mode. The latency on guitar and mic input, through the PodFarm effects is low enough not to interfere with playing.
