M-Audio DELTA 1010
I was running 2 of these in my windows 7 64bit machine up until early 2015. The only thing I found limiting was the fact hat they did not have any pre-amps in them which meant I had to use a mixer to feed microphone signals into the PC
I could run all of my outboard through the ins and outs without having to repatch anything
I would probably still have them if I had not serously downsized my setup.
