i'm looking for an amp for my proac speakers. At the moment i'm using an av pre (nad t175 with an arcam p1000) but i'd like to upgrade it choosing a stereo amp. What do u suggest ? Naim i5s, xs2, or 152/155? What does suit with proac better?
If by stereoamp you mean one amp =integrated amp
Then any Nait will do, something like a second hand 5i is usually a good purchase, so are XS which I think is too expensive new. The Supernait is the largest integrated amp from Naim, version 1 has dac inside, Supernait 2 has not.
The 152/155 is two box pre,power, not sure they are so much better than XS
The Nac 202 is a preamp only
Used Naim equipment in good condition is often free hifi as resale value could hold equal, once a friend had some 25 years old Nap 135 mono poweramps, they sold with no loss, owners of Nait 2 could be lucky selling with a huge earning these days
