I'm thinking, where can I find information about naming evolution of Naim products?
For example, what was the name of previous model of NAC 252? (the model, that was before release of NAC 252) Maybe Nac 251, or NAC 250? What is the system of naming in Naim products?
This is in case I want to by second hand product (to get the same class of quality, but older model)
