I’ve compared several B&W speakers to Joseph Audio, and in every case the JA speaker was superior on every level. You can pick up a nice pair of JA Profiles for only $2800, which is a great price. Frankly, I wouldn’t be surprised if they significantly outperform your 804 D3s that I’m very familiar with having worked for Magnolia. If for some reason the Profiles don’t work for you, you may well be able to resell them for no loss or even a small profit. Go for it! You will not be disappointed.
