I have an aging Presonus 44VSL which when I use an older driver at 24bit 48khz 128 buffers get me a roundtrip of 7.3ms, which is pretty decent. The problem is the driver is old, and the latest one is worse. My overall stability with the Presonus is driving me nuts.
I have ordered a Focusrite Scarlett 6i6. Hopefully it can replace the Presonus with less latency. If not I think I'll sell both of them and buy something else.
What do you guys have and use, and what is your roundtrip latency?
