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, 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.

Bvdiman, I am sure Dave agrees when I say that you have no reason to apologies. Those who have crossed paths with you on audiogon in the past know that you are a gentlemen. I have seen you more than once congratulating audiogoners (including me and Dave) for their humble equipment. Given the fact that you own top-of-the-line FM Acoustic and Accuphase products this says a lot about your manners and love for this hobby.

It is too sad that the audiogon moderators do nothing about Bo1972, i.e. Bobby Kingma from Sound & Vision Consulting. Not only is he trashing one thread after another by repeating the same things over and over again irrespectively of the topic discussed, but, more importantly, he is a dealer who shamelessly bashes the brands he does not sell and their owners. (For the record he does similar things also on the dutch sites, and seems equally illiterate and incoherent in his mother tongue.)

Which dutch sites you F. idiot? I am on no dutch site. You are talking bullshit. So you are a big lyer. We are going to take a person with Avantgarde speakers serious....yeah you're right, are you F. kidding me?

People who tell lies should be banned from this website.

I have pasted below a link to a dutch review for Bose:

Bose review with Bo1972's comments

Bo1972’s comments can be found at the end of this review. Those interested to read (again) the usual preach of Bo1972 (i.e. Bobby Kingma) should just copy/paste them into Google Translate.

I let you judge how petty is a "high-end dealer/consultant" who feels the need to trash Bose on the main dutch high-end site.

With this I rest my case.
Hi NVP, pretty good, you handled this like a lawyer that just won a case that had all the odds against him, I hope I never get on your bad side, Happy Thanks giving to all on this thread.
Hi Kevin, allow me to explain; we (the audio club) will be evaluating the Pass Labs amp on its own merits. It's not gonna be a Pass Labs vs. Bryston shoot out. We could do that, but I agree with you, it's kind of pointless.

Yes, I realized this once I got the speakers. This is why I'll be upgrading early next year. To exactly what, I dunno. However, the brands I'm considering are Pass Labs, Luxman, Accuphase, and McIntosh; leaning heavily towards Accuphase at the moment.

I hope this clears things up!
