The feedback from this power button feels kind of cheap. It is hard to describe this, pressing this button feels like pressing a smaller button behind it. This is about the only gripe I have with the MX-A5000 at this stage. This is not going to be a big deal at all because I am going to use 12 V trigger to turn this amplifier on/off anyway.
Not entirely sure what this A/B speakers switches are just yet. Guess I have to read the manual at some point.
Pardon the bokeh, this reads
Yamaha Natural Sound Power Amplifier MX-A5000.
Natural sound? Time will tell.
