@slaw I hyperlinked the word "This" |
Link all components, the Vishay foil have a 'sound' due to the leaded construction inductance. I question the use of 'naked' foils other than for cachet as they are subject to both mechanical and environmental conditions. Fanatical resistor precision is swamped by capacitor tolerances which are orders of magnitude larger. |
That's quite true, but I am convinced that much of what we listen to is dielectric absorption, or DA. This seems to be minimal in five components: bare wire, vacuum caps, air gap caps, nichrome wire resistors, and slightly behind these, Vishay VAR. Also, you can get exceedingly close to exact RC values by measuring capacitance and then specifying the resistance to high precision, which Vishay's Advanced Products Division (or whatever it's called now) will manufacture to your spec for a small fee. But it's rare to have an application which is critical to even 1%. Anyway, Vishay is one fine company to deal with, unlike some others I won't name. |
