Atma-Sphere Class D… Amazing

@ricevs I wouldn’t be surprised if @atmasphere agrees with some of your suggestions (or some variation thereof), but in retail world they’d also likely up the price by hundreds if not thousands of $$$. Gotta draw the line somewhere to reach a price point the market will bear, and from the impressions of current owners it appears Ralph made very good choices to reach his target price point. Then again, this is why mods in our world are popular and why manufacturers introduce “SE” versions that use higher-quality parts and design techniques.

The one thing I’d ask Ralph is if there’s a stereo version in the future that saves a box, decreases the price, and hopefully preserves most of the magic of the mono blocks (kinda like the AGD Tempo di GaN)? Just hoping 🤞🤞🤞, and congrats on what by all accounts is a ground-breaking new amp!

@ricrevs

I’m certain Ralph just slapped his forehead that his five decade journey in audio design is now complete. Congratulations Ralph!

I believe that @ricevs means well with his suggested modifications, but it's easy to be an armchair quarterback and critique the hard efforts of others. Ric have you given thought to bringing an amplifier to market loaded with all of your ideas to compete in this sector?

I too am a class D convert after many years and many amps.  It is really hard to say if they are better than class A A/B because of everything has changed along the way, speakers, preamps, DAC’s cables etc.  I still love tubes and will probably always have a tube pre with a tube regulated power supply, a professional (recordings studio DAC / Streamer) and class D Amps because of sound, weight and heat.  In summary class D with ultra fast switching (GaN) is pretty good.  Good enough to pay attention too.   I own AGD and don’t plan to change any time soon. They just work and sound great and should not be ignored when looking at amps.

A couple years ago Ric came out with his EVS 1200, based on the same IcePower modules that PS Audio eventually came out with using the same modules in their M1200s 9but at ~ 3Xs the price). Ric made a lot of improvements to the modules, though some issues could not be addressed. I raved about it in a AG thread that had many hundreds of followers, that is until my LSA Voyager 350 GaN amp arrived (about a year later). IMHO, from the first note, there was simply no comparison. Ric mods stock Voyagers, which may be the best audio bang for the buck going
