Class "A" as in Stereophile ratings: class A... class B etc. The mode of operation is less important than how well it is implemented, so no real answer there... As far as the rating sort of class... A better pre or a better amp? that is open to debate, but I personally would opt for a better pre than amp. if I had to choose in that manner.

And that most amps running in so called class A really run in class A only up to so many watts, when they glide into class AB. A "pure" class A preamp is pretty common, and you have a lot of choices... because that is where it really counts, in the low-level signals So I would say the preamp class A
