Naim audio has been part of my life for 28 years, and over this time I have upgraded steadily. I started with a NAP90 NAC92 CD3, into Linn Keilidhs, then moved to black series with a NAP150 NAC112 CD5, keeping the Keilidhs. A cat related incident wrecked one of the Keilidh bass cones, so I had a brief period with a pair of Monitor Audio speakers, before moving on again to a NAP300 NAC252 into Guru QM10s. This was also the point I embraced streaming with a Slim Devices Transporter as my source. I then introduced the Ovator S600s to replace the QM10s. Next the 252 became a 552DR, and the 300 was replaced by a 300DR. The Transporter was also replaced with a NDS with a 555DR PS. The Ovators were then swapped for Focal Scala Utopia V2s, and a little later the NDS was replaced by a ND555 keeping the single 555DR PS. This is the system I am listening to right now - The Alan Parsons Project - Eye in the Sky. I am expecting to upgrade to a NAP500 later this year. Is the the end of my journey? It certainly is for now.
