I believe that some ( especially me ) 2.7 owners hope the Rob Gillum comes up with a crossover board upgradeMake your opinions known here. Tom Thiel intends to help Rob Gillum engineer XO upgrades for multiple Thiel models . . . and he is monitoring this thread. He is working on his Power Points now, CS2.4 is probably next (actually, CS2.4 owners can get the SE version caps from Rob Gillum right now). CS3.5 is on his radar. I think the 2.3 would be easy given the similarity with the 2.4, 2.7 might not be too much more work. I suspect written requests in this thread will influence the order of model he works on.
This is an exciting development. I think these upgrades will bring Thiel SQ to a new level.
