I have the Quad 12L Speakers and they are connected to the Ayre AX-7e integrated amp. I am using the Ayre CX-7e CD player and MD-102T FM Tuner (tubes). Harmonic Technology Magic Link One IC (balanced) are used and the sound is excellent. The speakers are sitting on a Salamander Designs Cabinet. See http://www.salamanderdesigns.com/ cheers..
