having lived with lots(well over 20) pairs of high end speakers over 30 years, listening to hundreds for extended periods, and currently living with no sloutch gradients, ar's and castles.....there are times when i am certain that the original large and small advents where just about perfect. in fact, a stacked (2) pair of large advents still compete with pretty much ANYTHING. chapmans,hales,allisons and sotas were up there, but those adventsjust did everything right, and you didn't have worry about what they were hooked up to. friends who still own and swear by them, think that no reasonable person could make a case for needing more (ever)
