Class A or AB amp for JBL S4700 speakers


Which should I go for and why? Brands I'm looking at are Accuphase, Pass Labs, and maybe McIntosh.

Dave, FWIW, your speaker is fairly easy to drive with tube amplifiers. You might consider that- generally speaking, the extra smoothness offered by tubes will be helpful when driving that midrange horn at higher volume levels.
You might want to get a sound pressure level meter so you can be sure both amps are playing at the same level. First Watt amps don't make a lot of power relatively speaking.

My money is on the First Watt as being the better sounding amp within its power range.
In other words, it is class AB.

Class A amplifiers are class A right to full output.
