Moving on to the v6 upgrade question, these are the main new features of the 861v6:
1) Apodizing
2) 7.1 MMHR input
3) SpeakerLink inputs and outputs
4) Better (96/24) analogue input card
5) "Incremental" sonic improvements due to the new architecture, layout, etc.
and these are the main missing features (cards) of the 861v6:
6) Balanced analogue inputs
7) Tape card / copy zone
8) Video switching
I would add 6) Improved analogue output cards (Balanced & Non Balanced).
Video Switching [Analogue], missing yes but not major; who uses it these days?
UK trade-in prices, (not cheap & never will be) seem OK, would liked to have seen a difference between V3 & V4 values.
