Well, not exactly true. If the amp is underpowered, you run some risk with the M80s. Generally the brands recommended are Denon, Onkyo, Marantz (which tends to be overpriced), NAD (even more overpriced), and Pioneer Elite. Yamahas were in favor awhile ago, but I don't know of any current M80s owners running them.
