TL/DR from the review:
"There’s a thing about tubes that when it’s delicious, you can’t forget it. But it’s a road with a lot of detours. If your experience has mirrored mine at all, no doubt you’ve heard amplifiers with a silky smooth high end, others rendering a three -dimensional space that is so beguiling you might think you were under the influence of hallucinogenic drugs, yet others offer a delicacy that’s almost intimate enough to be obscene.
The CAV-45S2 offers all of this and a well-defined lower register to boot ...There is a cohesiveness to the sound created by the CAV-45S2 that still defies complete description. If this makes sense, it’s got the delicacy and low-level detail retrieval of a great SET, with the punch of a great push-pull amplifier ... you’ll find yourself having an internal dialog over how this can be so good for five grand.
Few material things in life are this close to perfection, even fewer at this price. If you have a room and system that can work within the constraints of a [45] wpc amplifier, I submit there’s nothing more fun or engaging than the Conrad Johnson CAV-45S2. It’s an affordable masterpiece."
(rhetorical) question: anyone looking for more in an amp than what mr drogay details in his review !?
