Graeme, it just goes to show there is no substitute for lengthy home demos.
You may be right in that the 11/12 year old 555PS might be in need of a recap/service, as others have had great results with the 272/555PS combo (HH) but we also all have our own personal preferences.
Let us know how it goes with the XPSDR.
HH has the ‘DR’ 555PS though.
Graeme - if the 555PS needs a service and that's why it sounds 'off', it might be worth exploring the cost difference between trading in your 555PS for a new XPS2DR and getting the 555PS serviced and DR'ed. As you know, Naim discount having a service and DR upgrade done at the same time. I can't help feeling that while initially a new XPS2DR might please you, you'll have that itch in the back of your mind about a properly sorted 555PSDR. Of course the 272 was developed post DR so Naim must have optimised the 272 to take its current and best PSU.
I did give this a little investigation MDS but decided I’d rather go for a new unit. It is a worthwhile (to me) amount cheaper to trade back the 555PS at no loss. The XPSDR feels like a well balanced final addition to the 272/250DR. I’d always have the possibility of a niggle that I was only using half the capability of the 555PS too...
...and we all know where that can lead.
