What class of amplifier has the most high definition sound ?

If there was a magic bean, don’t you think we would all have one?  Many choices, many tradeoffs and associated gear is among them.

The unstated inference is that anyone who agrees with what the magic bean happens to be, is dumb if they can afford it and don’t own it.

I found the match I like for my planars and understand others enjoy their amp for efficieny speakers.  There is no one size fits all “best”, no matter how much money you throw at the issue.  For those of us on a budget the choices are fairly proportional to the budget size and associated gear.

There are many great combinations at a variety of price points.  But alas, there is No magic bean.

I believe in Dilly Dilly.  

@georgehifi -- have u looked at Audiokinesis?

I read all this stuff about Class A and thought it was overblown, so finally bought the 8-watt Pass Amp Camp Amp from diyAudio store. Built it, used a Marantz receiver to drive it, and thought, hmmmmm, that’s pretty sweet. Not much volume into 89-dB speakers, but very “natural.” That’s my adjective for a sound that approximates an acoustic sound. A piano sounds like a piano, not a keyboard.

so I built another ACA for monoblocks, so now 15 watts a channel and good volume. I really like my Rogue Sphinx Class D into Magnapan 0.7s, and also my old Marantz, but I will say there’s something special about Class A. My experience.

@sacresta, I think I know what you mean by high definition and pure. That was my first reaction when I first heard a Class D integrated. It was a Primare I32 and it may have been due to their unique and proprietary implementation of Class D. I've never heard any other Class D, so I can't say; but defined and crystal clear was the way I described it. As a frame of reference, to me most tube amps sound sweet and mellow.
