Spec Corporation RSA-M99 integrated amplifier review is coming

A lot of people are highly interested in this unique integrated amplifier from Japan. Spec Corporation really tried to think out of the box with RSA-M99 by applying many of the unique approaches and solutions. The same goes for the looks. I really dig the aesthetics. Take a look at the initial photo set. I’ve tried to capture the mesmerizing and beautiful looks as much as possible.

I’ve managed to pull a few first listening hours with RSA-M99 and the sonic part is also a highly refreshing surprise. More about it later on, but this is for sure not your usual Class D amplifier. Quite an achievement!
