I don't have a problem with it.
If you pop the hood on a vintage Tektronix oscilloscope, a high-end Collins communications receiver, commercial test equipment, or old televisions, all from the "golden age," they look like this inside. Keep in mind that this golden age gear is a few orders of magnitude more complex than any piece of audiophile kit. Amps just have an amp circuit. A TV or multiband radio will have a dozen or more stages. The engineers had to plan them very, very carefully. That this gear still works 50, 60, 70 years later should tell you something about the skills of the people who designed them.
When you go point-to-point, you want the shortest route between components. That trumps "neatness," which offers nothing but aesthetics. If you want to use longer runs for "neatness" and run wires parallel to each other, you bring up an entirely different set of problems to deal with. While it might not look neat, short runs that minimize parallel wires and components offers the best performance.
It meets my rules, too. It looks like every lead is insulated and that every component is fully supported on both leads and the big ones are tied down. The wires are color coded for what they do. Can't see many solder joints, but the ones in focus look healthy. The amp looks fine to me.
It's not hard to work on, either. I've been through dozens of tube radios more complex than that.
