So Many great choice. You really have to audition at these price points. I’ve heard that amp with a few different speakers like Vandersteen Quatro’s (which is what I own) as well as Proac’s and a Wilson. I’m a Vandersteen guy obviously, but I loved what it did on the others as well. It’s a wonderful piece.
im sure it would also sound great with Harbeth, but you have to audition.
