So my better half has one of these & whilst waiting for her to get ready, quite early on in the relationship, I quickly paired my phone to it to have a quiet play - well it came on at full blast - I jumped out my skin! Very embarrassed! Anyway - I was genuinely impressed with the audio quality (once I'd turned it down) & ever since, had fancied one of my own although I struggled to get my head to justify that RRP price-tag!
This has made that sooo much easier. I did give PeterTyson a call ahead of the purchase (spoke the Ben - what a decent guy) & they've assured me that it's a Naim themselves (not PeterTysons) refurb & all of their stock of these are CAT A (A being indistinguishable from brand new plus, the warranty longevity is the same. I'm unsure if the box will be mint of course, doubt it will be but I didn't ask - I may report back here next week).
I think my other halfs' is the 2nd gen one (it has an HDMI port, which I *think* is the differentiator? Do please correct me if anyone can tell me if that's not an obvious differentiator - & what is of course!) so hers will probably need a firmware upgrade - which apparently adds some new functionality (which I quickly read on a forum).
Anyway, I can heartily recommend one, especially at £849, I think is a very good price for it. (edited)
