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 think Ralph will be working on bigger Amplifiers in the Class D Domain at a later stage. Remember this is not using anyone else module but he designed it from ground up.

If you have had experience With Atma-Sphere Amplifiers and pre-amps (I have owned every single unit) you will know anything that comes out off Ralph Little Lab is going to sound bigger and better than anything else on the market at the same price level and few times more. Its hard to beat his stuff at his pricing level.

 

Iv had amplifiers and Pre-amps costing 2 or 3 Times more and i still went back to his gear.

 

His Design may well not be everyones cup of tea, that is obvious as he tends to lean to Retro looking stuff. However if it comes down to Pure Sonic well those who have experience in comparing Atma to uber level stuff will know!

 

Iv owned every Amplifier from Ralph Except the MA-3 which is not practical for my needs.

From S30, M60, MA-1, MA-1 and the Nirvana

I own his MP-3 and MP-1 and the UV1

 

I have no doubt about this New Class D tech his working on!

it should be a concern for all the rest of the companies that are in the Class D Segment. Some of those companies are charging silly prices for bling boxes.

 

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.

Class D and Tubes amps all tend to sound diffrent. Iv heard some terrible 300B and 2A3 Amps and some good ones, Iv heard some horrible Class D Amps and some decent ones too. Not Heard the Atma-Sphere Class D Amps thou. Cant Comment on that. But Comparing SS Amps to Tube debate has been going on for years.

Anyway 300b & 2a3 cant power up anything much except very sensitive speakers with a relatively easy load to drive. Your limited on the speakers you can buy, Class D on the other hand can juice up even hard to drive loads with out issues or a change in the amplifiers character.

 

It also comes down to the speaker your choosing,

 

for me i choose speakers based on the amplifier i really liked. Which is usually the other way round for most audiophile.

 

I specifically looked for a 16ohm field coil speaker, The Classic Audio Loudspeakers not only fit the bill but sound more musically satisfying then anything else iv heard hence the reason why i stuck buy and bought another smaller pair the T3.4. They may not look pretty as other designs.

 

I also have the Line Magnetic LM3 Field Coils these are 16 ohms. I bought these just to pair it with the Atma-Sphere amps and it was out of curiosity but now iv decided to keep them too.

I love SET Amplifiers too, I am not just a OTL FAN! But OTL  don’t bore me as much as some SET amplifiers, it musical and fast, its transparent and conveys all the musical emotions over to the listeners just like SET can do however OTL must be paired with the right speaker to transform your musical room to something really magical!

Efficient speakers makes a lot of sense for audiophiles on a budget. The amplifier choices increase considerably aswell.

Tube Amps tend to behave like this where warm up time up to 45 mins is required for some amps. Especially Pre-amps which need some proper warm up times.
