Anything mechanical (Transducer's/motors etc.) then quality is usually proportional to cost (to a point); so turntables, loud speaker drivers, headphone drivers, microphones that kind of thing.
Anything related to signal reproduction is down to the selection of the components and the design. The components themselves aren't necessarily expensive. I could knock up a pretty decent headphone amplifier from a few scraps out of my spares bin and you could double blind test it against an amp costing a grand, and you wouldn't be able to tell me which was the more expensive amp.
My main hifi amp is DIY LM3875 based chip amp based around this design (LM3875-kit-instructions.pdf (audiosector.com). Components and case set me back around £180, and it sounds awesome.
People go mad when it comes to hifi cables. A cable either works or it doesn't. What I mean is if a cable alters the audio signal in any way that makes it audibly different, then it is either not fit for purpose (impedance mismatch due to capacitance or inductance, or resistive), or it's broken.
