I spent a year waiting for the right 552 to come along - early model, unserviced, but of known provenance - then had the full monty service done by AV Options in Chicago. One interesting detail is that, in addition to the PS recap & DR upgrade, they offer a rebuild service on the head unit which includes a new display board. At the time, this seemed (maybe) excessive but, given that I plan on the 552 seeing me out, I went for it. Considering the comments on the “**[How many defective 552s](https://community.naimaudio.com/t/how-many-defective-552-units-is-naim-going-to-send-me/12304)**” thread, I’m glad I did. --- _[View the full topic](https://community.naimaudio.com/t/non-naim-preamps-with-nap-300dr/12425)._
