Nigel, I have had a 222/250 and later added the NPX300 which I bought ex-demo for half-off the retail price. To be honest, buying the NPX300 was one of those things where I saw a great deal and jumped on it without a demo first.
From my personal perspective, the NPX300 was a small improvement. Perhaps I was expecting more of a transformative change which has been the case for other Naim amps I have owned. This makes sense since the 222 has a power supply built in.
My personal opinion is that there would probably better ways to spend my money if I had bought at MSRP. At half that price; I am still not sure.
Very solid upgrade to me on my 222/250, however my system only started to ‘sing’ for me when I upgraded the XLR and speaker cables to Vertere Redline. That made a massive difference and put me into ‘that will do’ territory.
Added a NPX300 to my 222 a couple of months ago on a very good deal, it was an immediate and very obvious upgrade to me. More details, musicality and a drop in noise floor. And the NC is a joy to use…
When I replaced my OC to NC system over the past 12 months, the only OC component I kept was the 555PS, which is now happily powering my 222. I have no idea how much of an improvement it is compared to a bare 222 as it was plugged on day 1, but I do remember the difference was jaw-dropping on my 272.
252/350/Kudos 606 is a winning combination of OC & NC for me. Moving from 300DR → 350 has been amazing. But I needed a 3 week home demo before pulling the trigger.
A/B comparisons between the 300 and the 350s proved challenging with Fraim break downs and rebuilds but it was worth it in the end.
Sorry, I took out the dot before com and replaced it with the word dot as I am never sure which links we are allowed to share. I keep getting told off about this so being cautious. Will amend my post to make it clearer.
