The Behringer is so cheap that you wonder what you're getting into, but it's actually not bad at all. I try to use it on less critical tracks, but I've honestly never heard any problems with it.
 
When my ADA8000 died, I looked for something a little pricier, but it wasn't easy to find another ADAT device with preamps that didn't cost more than my UFX. There appears to be an empty niche in the market. 

"When my ADA8000 died" tells about the product quality or lack of it. I had ADA8000, too, and it lasted 2 years 250 days before one power capacitor exploded. ADA8000 does not sound bad at all but I would choose something more durable like Presonus Digimax D8.

I use the Roland (Cakewalk) VS 700.  I'm also using an RME MultiFaceII that I'm using for conversion from some of my outboard mic pre's.  It's connected to the VS via ADAT.  At 96K it gives me four more channels of very nice A/D conversion.  I also have a Mytek A/D converter that's connected to the AES of the VS.  So at 96K I get 8 channels on the VS, 4 channels from the MultifaceII, and 2 channels from the Mytek.  That's 14 available mic pre's.  At 48K I can get 8 from the MultiFaceII.  So a total of 18 channels if required.

If you want to spend 1000 or under, get a used (or new) focusrite Saffire 56 but it still uses Firewire which BTW is compatible with Thinderbolt).   They can be had between 600 - 800 bucks and they're GREAT and have all the IO and features you'll likely ever need with excellent sound quality!  If you want to spend more like 2K, go with RME UFX, again you can save big bucks used.  RME is just SOLID and sound amazing and also have all the IO you would ever need.   There some impressive looking interfaces now by Antelope (Zen) but that may be Mac only.  

Focusrite Sapphire Pro 40.  Ive been checking out the UA Apollo's lately. Might need to get me one!

Rob, I'm retired and I just bought the Motu 24AO, after years using two Delta LT1010 cards. I thought I could use the LT1010 cards for the input, but I found out you can't use two ASIO devices at the same time, you have to switch to one or the other in Cakewalk. So I then bought a Behringer ADA8200 the newer version of the ADA8000. It gives me 8 inputs via ADAT lightpipe which goes into my 24AO and I use the 24AO as the master clock to the ADA8200 via a BNC cable. If you can clock 2 Behringers' ADA 8200 together (16 in) for $400 and use a Motu 24AO $995 (I used a coupon on musicians friend and saved almost $100) We are talking $1300 vs buying a Motu 24IO $2000~. Add 2 optical cables, 2 BNC connectors, plus the analog cables. 

I run 2 Lynx AE16e cards on the same machine using ASIO. Low latency and stability. I had the PCI cards before and the Lynx have been incredibly stable. Something I could never say about the MOTU 2408s that they replaced. Granted, you still have to buy converters (I have 8 channels of Mytek, 8 channel Lynx Aurora and a 16 channel Lynx Aurora). I can record 32 tracks at 192k without any issues. I could not be happier.

So far the Motu 24AO which I have going into 24 channels of my mixer has been great. I had to adjust the communications settings to be quicker, because after I played back a previous project using 16 channels with multi instruments, it dropped out. But I've never hear any noises or ticks like I did with my 2 Delta 1010Lt cards. But to be fair, M-Audio did not recommend multi 1010LT cards with their Win7 drivers. With the 24AO, when adding audio on those previous projects through the Behringer ADA8200, it has been perfect in sound and timing. As far as latency, if I use my midi or keyboards, I don't hear any, it's perfect to my touch. The only problem I've found so far, when recording a new midi track, there is quite a delay in the playback only, and I had to set the playback midi + delay real high value on the midi playback timing in Platinum, it's really behind. After making those adjustments, I was surprised it didn't affect my audio or previous midi recordings. Also after I've got the 24A0, it automatically loaded everything from the net. but then stopped being recognized once I started Cakewalk. I then switched the USB cable from my USB 3.0 to USB 2.0 connector, and haven't had a connectivity problem since. I used the USB 3.0 connector at first, thinking the higher bandwidth would be better. Right now I'm 99% confident I wont have any more hardware problems, midi or audio, recording or playback. First time I can say that in years. Whatever you do I hope it works for you. My hardware problems were taking the fun out of making music. Been using Cakewalk since Cakewalk DOS.    

Edirol UA25, later called Cakewalk UA25 (!) perfectly stable and with great preamps. If I had to change it now I would go for Zoom UAC2, very good preamps and comes with USB 3.0
