I have sought clarification of what is the ‘Naim Sound’ a number of times and from different angles over the period of my membership of this and the previous forum, my impression of what it is has coalesced over time.
The discussions in and around the following posts in the ATC SCM40 thread (https://community.naimaudio.com/t/atc-smc40/285/215) and the Is the preamp a thing of the past thread (https://community.naimaudio.com/t/is-the-pre-amp-a-thing-of-the-past/325/124) are pertinent.
