My subs are older class A/B RELs, and they don't seem to distort in any way I notice, even though they're driven by a 12WPC single ended tube amp signal...efficient main speakers help as nothing has to work too hard, and everything is clear as a bell and more resolving and seemingly accurate than any SS rig I've owned, and I've owned many...atmasphere "guilted" me in to a tube preamp (Schiit Freya) and although I rarely succumb to such heavy handed pressure from his over the top statement which I think was, "tube preamps pick up more detail" or something..."I like it. It's good" (Robbie Robertson line).
