I prefer the T1 sound card to any out there but some would argue, including Cap and JD Bass. That said, I do not use the T1 for stereo because doing so changes the functions of the dials and makes it, for me, difficult to operate.
I am running Model 1's not 2's but I can't imagine there would be much difference. Stereo simply sounds better and the phase cancellation issues of using 2 L1's in mono are is eliminated.
For some additional info on these topics check out these links. I hope this is sufficent until someone with more knowledge on the subject jumps in.
i have used the T1 in stereo with two L1M1s. it's sort of pointless for me. i use a DJ controller/mixer that would allow for stero set up. you don't get to use any other inputs since the T1 is setup just for sending the stereo source to two sides. you can't insert a mic and be able to control anything more than the trim. so if I need stereo and inputs I use a stereo mixer. if i need stereo without more mic inputs I just go from my dj controller to each L1M1
