Let’s not get carried away by the unforced, ‘unforward’ aspects. This is an energetic, dynamic, and detailed amplifier with outstanding imaging properties, and more than a little punch to its performance. It’s not governed by its beat, but neither is it unrhythmic in its presentation. But basically the CA150 is honest enough with its musical wards that not very well recorded music has nowhere to hide. Not in an exposed, etched top end detail way, but simply that well recorded music sounds so damn great through the c-j amplifier, you are disappointed when recordings not so hot don’t sound anywhere near as good as you’d expect. And yet, this amplifier is not stark in its portrayal of sound; it’s just so great on acoustic sounds, you want the same throughout.
I’ve listened to a lot of different amplifier designs this issue: some solid-state, some hollow-state, and some undergoing some kind of identity crisis. None have been quite so approachable, so listenable, and just so damn enjoyable as the conrad-johnson CA150. It’s a grown up amplifier for grown up listeners. It’s a refined, civilised design in an age that has forgotten what refinement and civility mean. It’s a lot more than that, too; powerful, dynamic, potent, and even rhythmic in outlook. In short, it’s a delight to play music through this amplifier. Firmly recommended.
