I just thought of something else, and this may have been put forward all ready, as we had been discussing the ever increasing prices I think a means to be able to work around or with that better for consumers over time is to make the trade in program that was piloted for just the 4B's last year a permanent thing, offered yearly but for all the products and not limited to a like for like trade up. So if someone got into Bryston with a 3B-SST they could trade that in towards a 4B Cubed, or a pair 7B Cubed for example helping to offset some of the cost in upgrading.
