I recently came across feedback from a user mentioning that the resistors used in the LAiV have a 0.05% tolerance, compared to the lower tolerance resistors (0.005%) used in other designs like those from Musician.
Could the company’s designer (if you’re following this thread) provide some clarification on this information and explain how resistor tolerance might affect the sonic performance of the R-2R DAC?
For reference purpose, here is some more information provided from google search. The typical tolerance of resistors varies depending on the type and application:
-
General-Purpose Resistors:
- Carbon Film Resistors: Usually have a tolerance of ±5% or ±10%.
- Metal Film Resistors: Often have a tighter tolerance of ±1% or ±2%.
- Thick/Thin Film Resistors: Typically range from ±1% to ±5%.
-
Precision Resistors:
- Metal Film/Metal Oxide Resistors: Used in precision applications, with tolerances as low as ±0.1% or ±0.5%.
- Wire-Wound Resistors: Can have tolerances of ±0.01% to ±1%, often used in highly precise applications.
-
High-Precision Resistors:
- Vishay Bulk Metal® Foil Resistors: Can achieve tolerances as low as ±0.005% or even lower.
The choice of tolerance depends on the application's required accuracy and stability. Lower tolerance resistors are used in circuits where precise resistance values are critical, such as in high-quality audio equipment or precision measuring instruments.
