I've been searching but haven't obtained a good answer on the subject. Currently, I have an STA-9 and have been inclined to try a Magnepan LRS or .7. Magnepan recommends a good Class A/B amp but I like my "9" with my Dyn X12's and Quad S-2's. (Not quite as good on my Zu Souls.) Does the "9" put out enough current to properly feed a smaller Magnepan? One reason I decided on a "9" was so I could double the output for not much more money-would that help? TIA.
