Post Subject: Physical attributes of devices matterPosted by drdna on: 3/17/2020
Every resistor, capacitor, tube, etc. are just physical devices that are optimized to come a bit closer to an ideal device -- a wirewound resistor may represent an ideal resistor, but it has inductance, capacitance, and other electrical and physical properties. All these properties have an impact on the circuit design. When one brand or type of device seems to "work better" in a certain position or application, it's related to how well it compensates for and interacts with the devices it is connected to. The goal is to get the overall circuit to closely approximate the ideal circuit on your schematic diagram to transmit your musical signal.
Understanding and keeping in mind how the devices that we select deviate from an ideal form (and what compromises are acceptable in a particular location in a circuit) helps to guide device choice. Listening tests are always important, and should serve to instruct us on our understanding of these compromises.
