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 love my tube OTL to death (not an Atmasphere but from a highly respected design engineer) so if Atmasphere can engineer a Class D that sounds as good or better than a quality tube OTL, that would be AMAZING!

@ltmandella maybe we can get @atmasphere to opine on whether (or how) one could bi-amp the class-D on the bottom (woofer) with your tube gear on MR/Tweeter?
(It is a fantasy of mine at least,)

I have heard many great things about Ralph’s gear.

There also seems to others doing some great work based upon those Class-D systems..,. So hopefully the high end market can allow for a few people doing bespoke gear to exist in respective geographic areas.

Are they all basing it off of the standard “Bruno parts”?
(with their respective additions and experience.)

you are describing the topology of a system having sdd-on subwoofer I guess.

@holmz No. The amp uses a module of our own design. I don't see why it could not be used in a bi-amped system.

will you, like Bel Canto now discontinue or gradually phase out your tube based models?

Its way to early to say. One big difference between our tube amps and the class D is the latter behaves as a voltage source with an output impedance of only a few milliOhms. Our tube amps are designed to be instead a power source, meant to work with speakers of higher impedance or speakers that aren’t voltage driven, like most ESLs. http://www.atma-sphere.com/en/resources-paradigms-in-amplifier-design.html

Well it is truly… Amazing as Atmasphere Music Systems new Class D mono amps have outperformed my MA-1 mk3.0 with NOS Tubes on the driver tubes in all areas…

FYI The OTL’s 1000watts of power at idle while the Class D only draws 10 watts at idle
