I had a pair of AP Avanti Centuries before switching to Wilson. This was an Avanti upgraded with the Caldera tweeter, circa year 2000. I ran them with CJ Premier monos and then Atma-Sphere MA-1s. Delightful speakers - I used them in a near-field setup. Although the woofer wasn't adequate for large-scale symphonics, their narrow baffle allowed excellent imaging.
