I have compared the 326s to the 523 then went to a 52 Ref. In short the 523 is much more detailed than the 326s and has a much larger soundstage. 523 won for me. The 52 Ref is better yet but I’ll give the 523 high marks as much closer to the 52 than the 326s. I bought the 52. Driving the 536s for all comparisons.
