Atma-Sphere Class D… Amazing

All this fuss. Class D is the affordable ticket to music heaven these days. That includes Hypex and Purifi.  You can bank on that. It’s just a fact. Not to say others cannot still compete.  Good sound is largely a subjective determination but all really good sound excels in the same fundamental areas that can be easily measured.  Looking forward to see and hear how the Atmasphere product compares.

@pstores 

Point, counterpoint.
 

You've shared your opinion repeatedly: yes, you like the Atmasphere class d amp after not liking others, which to you is something significant. Yes, you like it better than some Pass amps, which in your opinion also means something significant.

Your opinions have been noted.

I have provided an alternative view: subjective opinions carry no factual information. We must each listen for ourselves to find our own truth.

I have tried to move the discussion to the objective arena where discussion on the merits can take place based on facts and debatable parameters. I have mentioned such things as design, cost, value, performance, etc., in an effort to draw logical comparisons to other class d amps- rationale, objective parameters that apply to all amps and all listeners- things that can be legitimately discussed and debated, unlike opinions on how something sounds.

As a result, we have learned several things- what was patented in the design, why the amp costs significantly more than other class d amps, why a linear power supply was chosen when many class d amps use a smps. Unlike hearing how fabulous and great the amp sounds, this is interesting and useful information. Additionally, the designer has been patient and comes across as an intelligent and thoughtful person. Also good to know.

I am disappointed however in the lack of transparency regarding the measured performance of the product. In today's market, with several companies backing up their marketing department with a wide battery of test results, I can't help but wonder why this company refuses to share such detail, nor even give any explanation as to why they do not publish a more comprehensive set of measurements. Ultimately the measurements will be made by a third party and shared, so again, hard to understand the secrecy, but clearly, it is the company's prerogative so it is what it is...

I wish Atmasphere the best of luck with their product.



 

@kuribo well done on that post sir.
I think that there may be some effort going towards getting measurements done, but it will take a couple of months and the party needs to reach out to Amir.

nice post @sdl4 - But for some new here, Ralph is unknown, and taking his word on things from the 40 years of effort(s) is somewhat a “trust me” proposition when they are not involved with atmasphere.
I just became aware of them in the last year or so myself… but I am interested in them.

I found a review of the Prima Luna (with measurements) and therefore I would like to see the measurement of the Atmasphere. Then I could try and move the PrimaLuna on. If not I’ll keep it, and if I did, then I could consider making the jump.
I’d still have the tube front end, and I do not intend on that going anywhere in other than in a Charlton Heston fashion.

I think that this has been a tremendous thread.  Thankyou, Audiogon, and @pstores

"Clearly there is a lot larger market segment at $1000 than at $4000-$5000. I am sure I am not alone in saying that I would not pay $5000 for an amp that offers me at best similar performance to one priced at $1000- it’s a non-starter."

Seems like you made a subjective judgment - at best similar performance - about the Atmasphere amp without having heard it. Nothing objective about that. Also, you’ve made it abundantly clear that you are fan/proponent of other designers approaches. That’s fine, and good for you that you have found some that suit what you value. However, neither Ralph or any other designer has to be beholden to the design approaches that you favor. And, if they feel that their differently designed amps warrant a different price point that is their choice; they understand the market and their business objectives. No one is forcing anyone to buy anything. If you get musical satisfaction with Class D at the $1000 price point, great; if someone else gets Class D musical satisfaction at $3000, $5000 or whatever, great. There’s no right or wrong in that. Likewise, everyone is entitled to their own assessment and value criterion; again nothing right or wrong in that.
