These look like serious bang for the buck, but I'm cautious about purchasing because I have not read any specs on round trip latency for using VST's (including Scuffham for playing guitar in real time). This has way more I/O than I will probably ever need, but hell that is not a bad thing. I assume the pre's are just okay, but they actually have received decent reviews. What I DO like is that this is a full rackmount and has a full IEC power cable connection so it would fit in my studio perfectly, I also need USB, SPDIF I/O, compatible with W7 32bit, I want to have 1/4" line inputs and outputs because I will be trying to do some reamping with a modeler as well. I was going to go back to the Focusrite Scarlett 8i6 which is really nice (maybe better pre's, some decent software included) but I know the round trip latency is ~12ms and not adjustable lower so it lags a bit for use with Scuffham. To be honest Tascam might even be worse, but it's worth a shot and the form factor and additional I/O make it appealing at this price (~$300). Thoughts?
