That's great, making your own pair is only the work of a few hours, especially since I redesigned the kit. Never heard them on the end of any Naim kit, I haven't had any here for quite a few years now.
As I said before if anyone wants a listen I am usually around and you can either pop by and pick up my pair or rough prototypes or come to the house for a cuppa and a listen.
Thanks must go to James here for his hugely generous loan of his pair for what has been quite long term, well done, it's what PFM should be all about.
