My opinions stated here may not be popular but, above all I am a realist and I am just being real.
not only are they meant to be in equipment rack, unlike the HD621, but none of them are a direct HD621 replacement either in terms of functionality. they need to release the 621v2 vs Trinnov patch boxes that also do 4k if you happen to not sell off your 861v8 (and HD621). see what i did there?
