I also contrasted the NDX 2 with and without the XPS DR power supply, it sounds very good indeed without the supply but the extra control that the XPS DR brings does give everything more power, weight, and authority. Dynamics benefit from this and bass lines have a solidity that brings substance to the whole picture. It’s not essential and I enjoyed the streamer with its onboard supply for some time before adding the XPS DR: however, going back proved to be a less enjoyable experience. I’m told that the 555 PS represents a considerably bigger jump but it costs £2,600 more so you’d want a decent result even in the high-end world of diminishing returns. 

The combination tested here gets to the heart of the music in a fashion that is impossible to ignore thanks to the immediacy and detail resolution that goes with it. Naim understands that music like art is more than an aesthetic experience; you can only enjoy the sound for so long, it’s the musical message that makes listening so rewarding. Strangely, Naim is in a pretty select club in this regard, presumably because this has always been their ethos and because their engineers know how to achieve such a difficult to define goal. They have certainly scored with the NDX 2 and XPS DR... back of the net, so to speak.
