CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS

Slightly circular I think, because those words define the "market" as being those who like state of the art design, excellent objective performance, as well as a neutral and transparent sound. That is actually quite narrow, by my reading, and so large segment is correct but moot.

My own definition of "market" would be substantially wider, and would include other variables, without necessarily excluding those mentioned. Perhaps a different weighting scheme, for as is conceded, everyone has different tastes.

Perhaps by choice like yourself, or for other reasons.  Irrelevant.

 

My comments don't define the market in its entirety- I am simply noting that there is a great number of people in the market who like state of the art design, excellent objective performance, as well as a neutral and transparent sound- in other words, objective and subjective criteria are of importance, not just one or the other. The success of Hypex and Purifi, both commercially and critically, attests to this market dynamic.

I couldn't care less what others think of the sound of this or any other amp. What matters to me is my own opinion, in my room, in my system. The rest is simply noise. I want an amp that outputs a signal as true to the input as possible, only larger. I appreciate good design as verified and vetted by measurements as do others.

@kuribo From the website -

The Class D amp has the same kind of distortion signature {as tube amps}, but at a much lower level.

This, to me, is reasonably unambiguous. From what I understand of Hypex and Purifi (and others, of course) amplifiers, they make no such claim about harmonics. I suspect measurements may confirm this. I’d bet on it.

I’m as concerned about the definition of the market as you are with your amplifier preference. "in the market" would be the worldwide production and sale and availability of stereo amplifiers. Within this there are many other more narrowly defined markets like an overlapping mess of circles on a page, each with their own and overlapping characteristics.

So the "great number of people" must be taken in this context.

People, forget about Hypex, Purifi, et al.

The obvious point of comparison/competition here is the AGD Tempo di Gan.

Consider this.

Atmasphere: proprietary GaNFET module, 100W into 8, 200W into 4, $5400.

AGD: proprietary GaNFET module, 100W into 8, 200W into 4, $5500.

If anybody could get both amps in the same room at the same time, then they would really have my attention.

People, forget about Hypex, Purifi, et al.
 

Why? They are the current state of the art in class d amplification.

No, Hypex and Purifi are more concerned with producing a wire with gain, free from any coloration, tube like or otherwise. Their measurements bear this out as the harmonics, etc., are buried below audibility. If the maker of this amp provides similar measurements, we can make that assessment.

@twoleftears  That AGD price is for the stereo unit.    The Atmasphere are monos.

The AGD monos (Audion in satin)  are $7500. 

But even then, one coould speculate.....The question is how much of the difference in price is due to the bling factor and other stuff - the AGD bloke reckons somewhere that the cost associated with sticking a small city into the KT88 tubes is significant..  I'm not surprised.

Compare the pics, if you may, at you leisure.
