I don't track through the console. For tracking, I go from the pres to the recorder, then I run the outputs from the recorder to the console so I can have a cue mix from the console.
I haven't done any tracking yet with the MX80, but that's the way I've been doing it for many years with my 16-track deck, and will also with the MX80.
The only reason to track through the console would be if I wanted to use the console's pres, or maybe if I needed some kind of signal splitting...etc...otherwise going direct from my outboard pres to the recorder will always be the best/shortest signal route.
AFA as the Neve...

...I was only kidding, as I don't see a Neve desk in my studio any time in the near future...though I may find something in-between the Neve and the TASCAM, like a Trident or similar.
And while you can make a hit record with the TASCAM...it just won't sound as good as it could with a Neve.
Hit records and sound quality not always being one and the same.....
Oh, I like my M-3500...been using it for over 20 years now, and knock on wood, never had any issues with it. Some of the knobs are getting a little stiff, but it still sounds about the same as when I got it. I don't use any of the on-board pres though...just have better outboard ones.
