Positive_,
you forgot CDPS, XPS, XPS-2 and XPS-2DR... Not to mention XP5XS
Anyway, what I think some mean with Naim sound (and I am inclined to agree sometimes) is probably something that has to do with the basic choices that have remained across the different ages of PSU design by Naim, e.g. the choice of:
- powerful toroidal transformer
- big reservoir capacitor(s)
- simple regulators based on strictly selected LM317s
which seems to build up to a type of sound, in which drive, bass presence and control, immediacy of presentation are preferred over hyper filtering of current and complex regulation.
I'm not a technician, but I studied the thing a little bit. What I think many blame Naim for is the fact that LM317 is a very old regulator and Naim had, so far, not chosen to upgrade their design; anyway, a type of sound is apparently common to all modern Naim PSUs, as it appears from the many reports by those who have compared Naims and Teddy Pardos, ending up with rather similar impressions of each.
Ironically enough, having always been a Naim user and, in a couple of circumstances, been treated like a zelant passive follower on these pages, whe the DR came out I posted on the Naim forum assuming more or less than now, having the main design been changed radically, it could be finally argued what residual difference could still there be between Naim's and 3rd parties' PSUs, for which I was almost - if not banned - certainly panned by many.
Cordially,
M.
