CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS

All the specs he wants to share now are on his website. He has never published measurment graphs......most companies don’t. If you want more detailed specs than I suggest you contact him directly.

I think that if he wants to compete with the likes of Hypex and Purifi, he needs to publish measurements along the likes of the competition.

Don’t think so. His market is for people who REALLY listen and value how an amp SOUNDS and value his take on harmonic structure of the distortion versus super low standard measurements of distortion. All versions of Purifi and Hypex sound different from each other yet most measure the same. I have no doubt his amp will "sound better" than anyones Purifi....including my modded ones....of course, at a different price point. Some believe the measurements at ASR really mean something.....they do mean something....just not much in the way of how something sounds. Those guys do not listen so they have no idea if their measurements correlate to sound. Ralph has made state of the art tranformerless tube amps for years and his amps have been compared to other amps over and over....so he has a great reference for sound. ASR guys have no reference for sound....they just have some measuring tools.  I am pretty sure Ralph won't send his amps to ASR to be measured.  Maybe in a few years someone will send them their own pair and then you can whine about the fact that it does not measure as good in some ways as something.else.  Meanwhile, those that have the amps will be grinning because of the beautiful sounds it makes.

We all have different takes on things....vive la differance. Joy to you and everyone.

@ricevs thans for the link - I did not find class-D yesterday.

@kuribo I don’t think he is competing with Purifi.
I was thinking that his amps are all current amps, but the specs suggest a voltage amp.
All of his other amps are low feedback design, but this one is 35dB of feedback gain.

I am not sure what Hypex and purifi are in terms of feedback gain.

I wonder how well this new product will work with 16 ohm speakers? Sure, it will work, but, how effectively. This is a surprise for folks who have cherished the OTL designs for use with 16 ohm speakers.
