I asked Daniel Hertz and the US dealer if the Maria was similar to the PeachTree GAN1 but they did not go into much detail on that. Other than the A2D conversion for analog sources on the Maria what makes the Maria different from the GAN1. I know there are some differences but there are also similarities. These 2 amps are unique.
Since my modded GAN1 is so good, and I did not get a good understanding of how the Maria is different from the GAN1, I lost interest. I needed more power out of the GAN1 so it is now used as a headphone amp (amazing). My 2-channel speakers need more power than the GAN1 delivers.
The Maria can also use a remote control.
