CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS

@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.

But Ralph specifically says that his amp does have 2nd and 3rd harmonics at some level..

If I’m interested in buying a car that is grey, I don’t even think to bother the dude who is selling a red car for details about it.  That’s just me. I can’t speak for we.

But if I did wish to ask about why the red car is so much better than a dull grey car, I would do so politely and with due respect for the red's superiority.
