You are bidding on a brand new, unused Naim NAC 552 + 552 PS DR Preamplifier. Serial numbers: 451866 and 451812 All boxed, complete and immaculate. Happy Bidding! The NAC 552 is second only to our Statement NAC S1: its distinctive two-box configuration marks it out from the competition just as surely as its unfettered musicality reflects our core values. Its one of the best preamplifiers Naim have ever produced, and by extension, among the best in the world.On 11-Jun-23 at 17:29:44 BST, seller added the following information: A number of people have messaged me asking how this unit can be brand new when it is a few years since I purchased the item; a fair question and one I can answer. I bought a system a few years ago ready for my new house once I moved. Sadly, due to cladding issues post Grenfell, I have been unable to sell my apartment and so have not moved house. I have kept the system boxed and stored in my apartment, waiting to move house. The months went by and I now need the money and sadly need to sell the system. Hopefully I will get to buy another one some time in the future. I hope this goes to a good home and you get pleasure from it. Life is too short!
