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

Glad for your sharing of a happy 'find' experience.  Not sure if you're 'selling' or 'telling' though.

As one the members in your audience, there are some of who would prefer a 'live' performance over a recording. Price is the only measure surrounded by many superlatives. 

As one who prioritizes live performance over reproductions- the discretionary spending budget has different elasticity/inelasticity curves.  Compelling value proposition seems absent.  

Aren't reproductions nothing more than an aggregation of layers of artifacts?  

If the desired outcome is constrained to the conditioning of one's listening habits seems to there is a departure from fidelity of the original performance work to the recording/production engineers biases and preferences.    

Class D is about the needs for addressing increasing demand on our collective electrical supply. Not just quantity but, quality(s) and reliability, too.

The OTL certainly is one.

The GaNFET is certainly needed over the material limits of Si.  

Helper Circuits (e.g. Purifi/Hypex/Ghent..) are of materially benefitting, too.  

All these components require emerging test devices and measures to address integration.  Increasing needs for ever smaller precision approaching the smallest theoretical period of time. Only in 2014 we just deployed NIST F2 clock. On our way to Planck's length, or just 0.5 x 10-43 seconds.

Does the listening habits/training from live settings dissipating during audiences' quarantine & isolation? Is a consequence of performance-based fidelity displacing  the original performances work's lost if our venues are increasingly constrained to recording engineers biases and preferences?

Last then there is the TCO (total cost of ownership).  Is this approach really a sustainable business model?  Is blending Tubes & GaFNET, Helper Circuits & Class D just greater uncertainty (Heisenberg/Schrödinger)?

This statement appears false. Class D offers the possibility of using loop negative feedback in a way that was previously not possible due to stability concerns.

Legacy solid state and tube designs lack the Gain Bandwidth Product needed to support very high amounts of feedback. This causes the amplifier to have increasing distortion with frequency, resulting in harshness and brightness since the ear assigns tonality to distortion.

In addition the prior art has issues with phase margins in the design. Adding too much feedback can cause oscillation. For these reasons feedback has gotten a bad reputation with music lovers.

Class D offers a way around those problems.

'Apparently.' for the first. Your so-called 'Helper circuits' are class D modules so do not warrant a separate classification; the Ghent stuff uses Icepower modules so isn't a thing.  So winnowing out that bit of confusion, the answer then becomes 'no'.

“Class D is about the needs for addressing increasing demand on our collective electrical supply. Not just quantity but, quality(s) and reliability, too.”

LED lighting has had a massive impact on power consumption in the USA. I recall seeing a graph maybe 2-3 years ago that illustrated how LED lighting had changed the relationship between economic growth and energy consumption. E.g. for the first time in history electrical consumption did not track economic growth. 

Systems-of-systems-of-systems is a perspective challenge.  

I suspect few, if any, have measured the noise floor on the neutral at their home or work site. Particularly, over multiple-time studies of more than 1 year. 

There is much more worth learning about from DOE, ESRI, NRCC, IEEE (e.g. Greenbook) and the AFRLs have much more to offer. 

Caeteris Paribus is deflective, at best.  Quixotic still.   

Between the GPR/EPR and then the neutral floor noise rise, the advance of the NIST-F2 clock integration, RF energy harvesting & distribution, more consumer DC appliances, EV charging stations...bucolic reminiscence will only provide more melancholy than fidelity.
