Hhmm...
"there are other, perhaps better, forums"
Sorry. I have got great information from this forum. Great professionals sharing their experiences from this and that. Many times manufacturers send some copies of the "beta-versions" to selected users to beta-test and they are allowed to share their opinions. Maybe you should find an amateur site where you can post your "not so clever" answers, maybe you will find soul mates there.
"you should keep in touch with TASCAM"
When you are talking with manufacture representative you normally get adjectives like: "gorgeous", "magnificent", "unbelievable", "super" etc. They are sellers. That's why I asked about Pro-opinion.
I'm heavy user of Sound Devices 788T, MixPre D, Lectro wireless, Sennheiser mics etc. but there are cases when you get job done with lighter kit: Tascam DR-70D???, Roland R-26 even with Zoom H4N etc.
"You get what you pay for" but sometimes "you get paid very well even you are using semi-pro set", if you are capable to squeeze from the product and hit the goal.
Like cameras.
Arri Alexa is fantastic camera and giving superior picture but some times Canon 5D etc. will get the job done.
And I noticed that there seems to be also others who are interested of this product.
