I have an almost complete QUAD system: I am driving the speakers with the QUAD II-forty monoblocks. My pre- is the QUAD QC-24, and my source is usually the Musical Fidelity Tri-Vista CD/SACD player.
One weakness that I regularly notice is that at high volumes and high frequencies (i.e. loud soprano), I will hear some distortion, but my amps and pre- are near the speakers, as a matter of necessity, because of limited space, and I suspect that this fault is due to feedback because of my mediocre setup.
