Let me give some examples, since I have some technical knowledge in this area:
1) Film resistors - these are lower inductance and lower noise. They reduce the thermal noise that causes the hiss at low levels that you hear. Does not affect tone.
2) Poly caps (polypropylene, polystyrene) in the signal path - these reduce dielectric absorption. DA causes time smearing of the signal. also does not affect tone. This is a dynamic effect.
3) Power supply cap increase - this provides more capacity to respond to high-power events, so dynamics can be improved. prevents voltage sags when high-power events occur. does not affect tone. This is a dynamic effect.
4) high-frequency, low internal resistance caps in the power supply (decoupling caps) - Improves response to high-frequency transients. Prevents truncation of transients because the power system can react faster. This is a dynamic effect.
Changes in tone are changes in amplitude as a function of frequency. It is a steady-state effect.
As for my system, I have 3, so I will describe my reference:
Source: Sony DVP-S7700 transport
Pre: Proceed AVP
Amp: Coda 10.5
Spkrs: KEF reference 104/2
Cables: Empirical Audio
This shows that old components, particularly speakers can still be reference quality. Also, you can get 95% of the performance of the most expensive reference components at a fraction of the price.
