I have a collection of sets from Altronics cheapies, to DC 10-30s, to the DC ENC. On any given day I will jump from a piston single, to a pressurised turboprop, to a piston twin; and the DC ENCs are simply fantastic in all environments. I would like to try a Bose too, but I am very happy with the DCs. You need to find someone who has a type you think you want and borrow them for a days flying - there is no other way to really test whether they will deliver what you want.
