What you're seeing is the signal schematic. Note the power supply isn't even shown. Rather, it's implied with a simple +/-63 volt indication on the far right. If we had the complete schematic we'd have a second page that showed the power supply as a separate and (almost) unrelated diagram. In reality, they are not separated, just like my example of your circulatory plumbing.
When we look at the power supply and amplifier as a unit we suddenly realize the amplifier is a mere extension of the power supply, not the other way around. The valves (be they transistors or tubes) control the flow of what the power supply is capable of delivering. Here, power supply speed, current, transient response, wire or circuit trace impedance, energy storage and recovery, and grounding issues all play into the quality of what we hear.
So, the answer of whether or not power supplies matter as much as circuitry is a simple yes. Hell yes!
Power supplies are equal in importance to amplifier circuits
