I agree with the reasoning for 12 and 16 channel receivers in the range. Personally I use many of the usual PB units (including the small but yet cumbersome, Expander) and still have a number of models where these are simply not the answer. Whilst PB has created fantastic new options, they do need to recognise the fact that it will need to replace existing installations in many cases - so please PB, make it a little easier for longstanding modellers to make the switch.
