I don't have any doubt those Keels will all sell, and all within the next couple of years
The Keel for Aro is a fine invention, and one which has caused an impact to pre-owned Aro resell values, the Keel raises the performance of the Aro to a very high degree and we can account for Aro pre-owned values rising over the years since the Keel for Aro was introduced.
Also, the success of the Aro/Keel has become well documented and has attracted much attention, given many Aro owners who have lost interest in vinyl the incentive to sell them to people who seek them. Aros that are lying around in storage will come out to find new eager owners who are aware of their potential, plus many Aros are used on alternative turntables that could be described as outdated and lesser than an LP12 in music making capabilities, these will also gain the incentive and option to jump ship to LP12 with Keel.
Naim HQ may become busier than usual with old Aros going into dry dock for service and check-up.
