I agree with Phd (and Ralph, as well, given the simplicity of his circuit designs). I also agree with Sugarbrie that effort expended in trying different speaker placements, including crossing both in front and behind you may radically improve sound.
8 feet is fairly close, yet even a foot or two more of semi-nearfield listener position may allow the use of a lower power, high quality amp and lower average listening spl.Of course, I'm one of those whose high volume listening days are way over. Well-mated components do the lower volume thing in a very satisfying manner and gain much greater acceptance from those sharing your domicile.
