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'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.

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.
