Level 3 and 4 in the SW line can absolutely hold its own against classic brands and most newcomers all day long.
I don't know if I'd agree with this statement. I didn't shed a tear when I sold off my Encore II interconects for (I believe) a less expensive offering from PS Audio. Even when I sold my cables, I told the buyers that the PS Audio cables were much better, but I guess at the price I was selling them for, they couldn't pass up the SWs.
