100% Marketing Hype no question. 🤣😂😅

The review I linked to was a bit confusing to me. I am under the impression that the Maria amp is a Class D amp (maybe GAN) with the digital conversion done in a chip. The chip does more than a standard DAC chip

I am thinking the Maria is something like this,

What makes the GaN 1 so special?

First and foremost is the GaN-FET amplifier module. It has several inherent advantages in a power amplifier that even the best MOS-FET designs simply cannot achieve. A GaN-FET power stage provides a precise high-power reproduction of the Class-D PWM signal with extremely high linearity. This linearity eliminates the need for ANY feedback, ultimately allowing for the best possible audio quality providing clean, clear middle and high frequencies and a tight, solid reproduction of low frequencies. GaN-FETs track the complex audio waveforms so much more accurately than MOS-FETs resulting in significantly more transparent and natural sound. The difference is something even a casual listener can hear and appreciate. The GaN 1 is also designed so that it does NOT even require a digital-to-analog-converter (DAC). The digital audio signal at the input directs the amplifier outputs to drive the speakers. Although DACs have continued to improve over the years, there is no DAC better than NO DAC! This concept is not a new one as similar devices often referred to as "Power DACs" made quite a splash in our industry years ago, but this time around, using the concept with GaN-FETs raises the bar to an entirely new level.

When I first saw S. Huff's review of the Daniel Hertz's Maria w/ Eva system, I was excited to make plans to go up to N. Cal for an auditioning. But after seeing all the comments and using some common sense, I was a lot less excited, thinking perhaps this is more marketing hype than substance? Class D, light weight int amp, small cooper speaker wires b/c the amp was tuned to it (really?), and the ground breaking software decoding that transforms digital to the most analog experience ever, if these were true, than the entire audiophile industry got it all wrong. Add on the history with Redrose Music, Mark's treatment of Jonathan Curl, and let's not forget his history of companies:  Madrigal Audio Labs, ML, Cello, Redrose Music, and now Daniel Hertz. I was skeptical at best and found peace laying it to rest. 

That's until I saw the review by Adrian Low at Audio Excellence, a person whom I respect as a straight shooter. Now, that aching question returns. Is it really as good as M. Levinson claims? We need OCD Mickey or Jay Audio or others to review this damn system and give us some unbiased reviews. 

He did?
