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

@atmasphere Any plans to develop a higher power version of these amps, or a stereo ~350 wpc doubling into 4 ohms class D (similar to bel canto black ex) with the same sonic profile as your new monos?  I'm asking because I wonder if these 100 watt class D monos have enough testicular fortitude to drive <89 dB efficient speakers with grunt and authority. I would completely understand if you chose not to answer the above question ;)

Generally speaking I'm not a fan of low efficiency and hard to drive speakers. This is simply because the harder you make any amplifier work for a living, the higher the distortion, and with that distortion comes a less relaxed presentation (due to the generation of higher ordered harmonics) and less detail (since distortion obscures detail).

89dB is borderline low efficiency. A lot depends on the room and your listening habits as to whether 100 Watts is enough power or not. The speakers in my bedroom system are about 90dB and I play them with an amp that only make 5 Watts with power to spare, no worries. You have to take the room into account.

Look at Merrill audio they started off reasonable .

now because they decided to use the latest in digital they go Waaay over 

priced by making a fancy cabinet at 10 x the mark up , a truly good engineeer 

Will offer Amps preamp $5-$10 k.  That shows skills  .

the vast majority of Audiophiles cannot even afford  $10k 

amplifiers never mind like Merrill $30k units .  Think on being practical it’s a hobby to enjoy not a mortgage !!

Not sure they even started off  "reasonable". There first product, based on the nc1200 by Hypex was around $10K as I recall. You can get a nc1200 based amp these days for less than $2000.

I don't believe Merrill has published much at all by way of measurements for the new $30,000 amp. I have no doubt the Purifi based amps, at around 1/30 the price perform at least as well if not better, but they don't come in a shiny case.
