There are two "speed issues". One is the switching frequency (400K to 1.5Meg) and the other is the speed of the output device. GaN transistors are faster and have less overshoot and ringing than mosfets so therefore have less intrinsic dead time. Which of these to "speeds" make a sonic difference? Some people claim both do....some claim only one does....some claim that 500K mosfet switching is fine. If you could take an amp with mosfets and change it to GaNs and listen without changing anything then you might know about the intrinsic speed. If you take an amp and raise its switching frequency without changing anything else then you might know about that. If these sonic tests are not done then you are just guessing..
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 don’t understand the title: Class D amps buy atmasphere…it appears to read as if Class D purchased Atmasphere. If it is supposed to be “by Atmasphere” instead of buy, then I get it. On the current state of sound regarding Atmasphere OTL amps. I attended the Florida Audio show for a few days and listened to the Novacron and new McIntosh Mc3500 driving the Classic Audio Loudspeaker T1.5 reference. The sheer dynamics of music were easily reproduced by using the Novacron mono amps. The bass was quick, solid, and deep. The rest of the audio frequency spectrum sounded just right without any noticeable negative aberrations in sound quality. It was just right and pure. I also thought the Novacron sounded more natural, well,organic, compared to the 3500, but that was not a direct A/B test. My takeaway is that the Atmasphere OTL Novacron is an incredible amp. It will be interesting to hear industry and consumer feedback regarding the new Atmasphere Class D amps.

@audioquest4life Have listened to the Novacrons many times at a local dealer and agree a wonderful amp BUT must be used with correct speakers that have a high impedance to do their magic. |
I agree wholeheartedly. It seems like the 16 ohm, 101db efficient Classic Audio T1.5 reference are a match made in Heaven when mated with the Novacrons. This journey is so full of variables and listening tastes, it is hard to make an absolute judgement call for what is best for someone’s system. I think my McIntosh MC2301s pair very well with the T1.5s and I get equally good sound with that combination.

I run Atma-Sphere Nirvana OTL Amplifiers, on the Classic Audio Loudspeakers i posted the pictures over whatsthebestforum. The nirvana at times Powers up the 16ohms T1.5 or at other times the Line Magnetic LM3 which is also 16 ohms Field Coils.
I owned the Novacrons for some times excellent amplifiers. |
