New Interface Recommendation (with 8 mic pres, plus 2 ADAT in for 24-track simultaneous)?

I'm looking for a new interface, that "plays well" with Sonar. But apparently I record way more simultaneous tracks than most of the search entries I've found.
 
I'd like to be able to capture 24 simultaneous tracks.
 
So I'm looking for something with 8 mic preamps, plus two ADAT intputs.
 
1394/Firewire or USB doesn't matter to me, as long as it can keep up and is stable.
 
I currently use an Alesis IO26, with an older Presonus DigimaxLT plugged into the ADAT input. I'd like to keep the Digimax, but the Alesis is starting to show it's age. Some of the LED's are fading.
 
If there's a recommended Firewire or USB card known to play well with your recommendation, I'm all ears. My card does have the TI chipset, but is also very old, and has been transplanted from my last few computers - its probably earned its retirement as well.
 
 

It looks nice. A little spendier than I'd like, but you get what you pay for right?

Stack up 2 units of Roland Studio Capture, total of 32 inputs (24 preamps), no ADAT.
 
edit : also the RME RayDat (PCI-e) up to 4 ADAT.

I love my steinberg UR824 it has exactly what you need

+1 I wanted to transition to a USB device after years with MOTU PCI & FW (which were great!). Really happy with the UR series and settled on the 824 for the same reasons mentioned above.
