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.

When I added the XP5xs to my 272 things really opened up and just recently I was contemplating a none DR 555 for my next upgrade as I cannot stretch to a 555DR so your comments regarding the none 555 are interesting. Personally I don't think a service is due on your 555 as the service period should be every 15 years on power supplies.

On the Naim website they recommend XP5xs for the 272, to me the XP5xs is a very nice upgrade and I may just stay put.

Hasn't Naim recently discontinued the XS series? 

Not the “series”, but I think the XP5XS (!). The ND5XS is still running - and I suspect with good reason, probably outstripping other streamers - unlike the XP5XS. (But that is only my guess, as I don’t know actual sales figures)

New XPSDR just on for a few tracks. Played ‘Telegraph Road’ to see how the noisy/complex last few minutes is handled and early indications are very favourable. The 272/XPSDR feels complete, like a whole player as one, rather than a modest source with a turbo-charger.

I only had about 20mins of ‘me time’ so will give it a proper listen tomorrow.
