CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS

CLASS D AMPLIFIER TECHNOLOGY HAS FINALLY ARRIVED TO OUTPERFORM ALL OTHER TOPOLOGIES 

The Amplifier is the New Class D Mono Amps using GaN Fets in a unique Patented
Circlotronic output stage…Design by Ralph Karsten of ATMASPHERE MUSIC SYSTEMS 

Rated at 100 watts 8 ohms and 200 watts 4 ohms with low distortion across the full audio bandwidth with excellent noise characteristics 

I have been using ATMASPHERE MUSIC SYSTEMS MA-1 3.0 with all factory upgrades along with NOS 6NS7 Input Tubes for many years 

The New ATMASPHERE MUSIC SYSTEMS CLASS D has outperformed my MA-1 3.0 in all areas…the resolution and transparency are simply an Amazing Accomplishment

Also I sold my MP-3 mk 3.0 and purchased the New MP-3 mk3.3

In my Audio opinion I believe the ATMASPHERE MUSIC SYSTEMS CLASS D MONO AMPS used with the MP-3 mk3.3 will offer one of the most transparent sounding electronics combinations to date…only using the MP-1 mk3.3 will offer more performance 

I have used other High End Amplifiers in my system and the ATMASPHERE MUSIC SYSTEMS CLASS D MONO AMPS outperformed all of them as well

I am confident that Ralph's GaN amps will be/are awesome.

I just wrote this on another thread: FWIW: My experience with class D goes back to PS audio GCC 250, which I still use in my video system, but in my 2 channel audio Ive had several W4S, Emerald Physics 100.2SEs, Audio Alchemy DPA-1 (excellent sound but I need a lot power in my room), PSA M700s (also soundd nice), EVS 1200 which I raved about for a year UNTIL it was replaced with a LSA Voyager 350 GaN amp. The Voyager is ~ half the power of the EVS, and yet sounds twice as room filling. From this experience IMO, GaN is so superior (at lease when done right) to conventional class D that it SHOULD have a separate designation. Switching Speed is the juice

The photo posted by dill looks just like the Atmasphere class d amps at the Florida Audio Expo in the Unique Audio room.

Switching Speed is the juice

Possibly but this atmosphere class d GaN amp actually has a lower switch frequency than most mosfet class d amps on the market, so I find this comment irrelevant to this discussion. And, other than a Technics GaN amp that came out over a year ago, none of the present GaN based class d amps have a switching frequency materially higher than most mosfet class d amps on the market. So, a claimed major benefit of GaN technology for class d amps, a higher switching frequency, is in fact not even being exploited.

Has the price been mentioned yet? I just kind of skimmed through the posts and didn’t see it. 

More to discover
