Class A or AB amp for JBL S4700 speakers

Dave, sorry to make a train wreck out of your thread--my first time ever! ;p
Just thought you actually knew more than them smartasses and deserve better than all these BS advises--making out imaginary sound from reading/hazy past experiences without the need to actually listen/compare themselves. So sad.

No problem, Bvdiman, you know what the good stuff is just as much as anyone else. I value your opinions, especially about Accuphase. Anyway, I'll chat with you more on that *other* board we're on!

Simple answer Dave. Your brands are all fab!. Buy 10 or 12 times the power you think you will need for regular listening. Your headroom is then just satisfactory and, with some great power conditioning on your source and amp chain, you will rock. Enjoy.

Sounds like a plan, Ptss. Thanks for the suggestions!

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.
