200 watts into 4 will not drive Apogee speakers, Magnepans to great volume, various Wilson, etc. speakers. There are no ohm taps on a transistor amp. The output impedance on Ralphs amp is low......but the voltage/current it limited. Works the same on class d and class A or A/B. Purifi has a new module about to be released that has 40 amps of current instead of the 26 for its current model. This will make it double from 250 watts at 8 ohm to 500 at 4 ohm and even puts out 900 watts into 2 ohms......now that will drive more speakers, for sure. I am sure Ralph will do something similar. Myself.....100 watts is plenty. But I have easy to drive speakers.
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 agree high power is necessary for low sensitivity loudspeakers speakers, I built the GR RESEARCH NX OTICA with Servo Woofers…which are 93db @ 8ohms…16hz-22khz in an open baffles design…I have servo set to high damping @ 20hz Paired with the GR Research NX Otica and Servo Woofers… Atmasphere Class D mono amps with 100 watts @ 8ohms are simply incredibly transparent and the most open soundstage I have ever had in all my audio journeys BTW I am using the Pass Labs XVR-1 that I upgraded with Polystyrene Capacitors Thanks for Reading

In comparison to what or perhaps I should say...who?. "Neutral", even without a demarcation from music’s fundamentals of timing, tonality and dynamics, for some, would be "less". I’ve heard the otl amps and one of my favorite topologies. How does one achieve "more neutral" or are you not saying that?
