What class of amplifier has the most high definition sound ?

what class of amp is the High Definition kind?

short answer? The High Dollar kind.

almost invariably greater fidelity goes hand in hand with more investment. despite ‘class’.

A, A/b, D, Hybrid, Tube amps which have an enormity of classes based on their output tubes, all have different levels of audio definition, or resolution. as the entry fees escalate in each camp, usually their resolution increases commensurately. there are over achievers and we all seek them out, but usually, more money means better most often. 

 the buyer beware note here is that it will take more than just an amp to realize the amps true abilities.

there needs be a great source, and of course, great speakers, or at least very competent ones.

a pair of Hiesenberg monos at $100K running into a pair of say, Joeseph Audio Pulsars isn’t gonna express the entire bandwidth as revelatory as they would with say, a pair of Legacy Aries.

amps are key, but so is the rest of the rig.

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.
