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?

Does anyone have any idea of how this amp might sound at medium volume levels in comparison to a Modwright KWA 150? ( which I currently own ) I would assume a finer grain and less texture?

Unfortunately, I have never heard a Pass amp.

Never heard one, but should be ok grunt wise to handle the low loading between 70hz and 150hz for the bass, all depends on the rest of the design to how it's going to sound in the mids and highs.
