I agree with microstrip/bruce , with the right pairing and high quality tubes you can have outstanding bass , another comes to mind is Octave jubilee, they are quit costly to maintain however some of these poweramp s.
Remember the 9600 are something like 70 or 90 watts , and the Q 7 is a large speaker which benefits from quite a lot of control i think
