Even for a prototype, that assembly is a bit messy, and it's probably audible. I wouldn't make any decisions based on the sound of that circuit in such a state. Simply twisting leads together would probably be a better strategy than globs of cold solder joints.
Smaller value caps in parallel with other film caps can be useful when the smaller cap is better quality. Otherwise, it just doesn't make much sense and only complicates the circuit. I don't understand why you advocate making every doubled wire exactly identical lengths, yet you run the delicate high frequencies through multiple capacitors of vastly different signal path lengths.
Caps should not be suspended in air by their leads. They should be securely fastened to a solid surface and damped to reduce vibration. Your o-ring idea is worthwhile but the caps still need to be secured.
