I owned and enjoy Naim equipment from about 1990 until 2019. It all sounded very good to me.
I owned the 72 preamp but eventually replaced it with an 82 preamp. Both powered by a hicap.
I went from the little 140 power amp through a couple of 250s and ended up with 135s. I enjoyed the 82/hicap/135 system for many, many years.
Now I've switched to tubes and love the sound of my system.
I think the comments suggesting that people who have only listened to Naim equipment apply equally to all brands. It is a good idea to broaden our exposure to other technologies, systems, pieces of equipment, engineering, synergy and music.
I like the folks at Hawthorne and they have treated me well. They do a good job representing Naim and have many very satisfied customers. The folks down the street at Definitive Audio also have many satisfied customers.
One criteria that doesn't get mentioned much, but that i think is important, is how long people tend to keep their equipment and be satisfied with it. With respect to that measure, my Naim equipment was very good. I kept it a long time. By comparison I read many posts here and other places where people were always wanting to change something out. They were never satisfied. I, personally, dislike that treadmill.
Best regards,
