Class A 30 Watt Amps: Are they enough to drive my book shelfs?


Currently looking at buying a Pass Labs XA 30.5 to drive my Kef 201/2 speakers which are rated at 86 DB sensitivity.  Is this a bad move?

Unfortunately when I was looking at them, most articles described them as "pure" Class-A, not high bias AB like they really are. Thank you for clarifying.

I could be wrong, but I thought the Pass Labs XA 30.5 was a true Class-A amplifier, and true Class-A amplifiers don't have headroom.

All are sized to achieve a price point. Other components are designed to deal with ... heat. If an amp truly could produce more power within specs, certainly the manufacturer would publish that capacity. It ain't so. Measured distortion prevents a larger rating.
