Amplifier for my new Focal Sopra no2

Need to study, do audition and start savings...

That’s where the fun is...

Your Naim NAC N272 is upgradable with the addition of a Naim external power supply unit such as the XP5 XS, XPS or 555 power supply unit to achieve better sonic results. You should try that and will be rewarded with the results. 
Naim products can easily be upgraded by adding Naim's external PSU. 

Yes.  I have studied that as well and a friend, who is a big Naim fan, strongly suggests the upgrade of power supply.  His view is that sound would be more airy, rhythmic and musical.  

Yes indeed. Adding a Naim external PSU will significantly improve the sound quality and musicality.

Or alternatively there’s always room to upgrade to a higher end Naim standalone analog linestage preamp with external PSU and a separate Naim streamer + separate Naim DAC as well as upgrading to a higher end Naim power amp with external PSU, which will take the overall performance and musicality to a whole new level.

This upgrade path thing of Naim is both good and bad.  Audiophiles always want to try something different and new, and Naim limits them from connecting gears of other brands.  For instance, cannot connect with balance inputs/ outputs.
