Colin Wonfor’s Clinic: What really are computer grade parts?

Colin Wonfor

Dear Colin, Computer grade parts? What are computer grade parts.. such as Computer grade power-supply caps? Are these type of parts an upgrade and/or better than audiophile grade parts? For example, I've heard some people say, "I've upgraded my power supply caps in my amp to computer grade caps". I don't think I'd want computer grade parts in my audio equipment for playing back music. Would appreciate some clarification. Thanks.

Normally the capacitor are large in value and have much higher ripple current ratings and thus run cooler and their internal resistance i.e. ESR is lower which reduce the noise at high frequency which is what is always produced by digital lies.

Thank you for the question.
