Took my Nait & speakers to Nintronics last Friday as I'd arranged for a demo of the NAP200DR & also NAP250DR.
Started with the 200 & was impressed by what it did to my little NaitXS. The 250 was a different beast altogether, once I had gotten over the initial wow moment and the more I listened, the more I preferred what I heard from the 200... The 250 seemed to put a vice like grip on all aspects of the music & didn't appear to let my speakers sing like the 200 did? I have to say I went in under the impression that once I'd heard the 250 I'd be reaching for my wallet but the 200 was clearly right with my other equipment & my ears! Maybe the 250 was just 'too much' for my Nait as CDBOY mentioned above...?
Job done & the 200 is now residing at mine on a 2 week home demo period. I'm very much enjoying what I'm hearing so far & it seems (to me at least) that Naim's advice on upgrades in the manual was bang on
Going forward I will return to Nintronics to audition a NAC202 or 282 next year at some point...
Thank you for all your helpful comments folks
Enjoy the music!
