I've matched resistors before. like if I need 2 pieces, I double that quantity.

But somehow I am beginning to wonder if it's a wasteful/worthless endeavor since the resistors in my CD player wouldn't be matched.

any thoughts?

Thank you.

I only try matching the generic resistors w/ tolerance of 20%. I thought ppl buy 1% resistors so they don't have to match. 1% is good enough for me.

In two wire mode with a cheap meter you might as well just be guessing because you are going to get similar results.

yes, the point of getting 1% tolerance resistors is so you dont need to match them, but there's still that +/- 1% possibility of difference, so more dedicated enthusiasts will match them anyways.

edit to add - i'd probably be too lazy to match em.

The reason people go buy 1% or better resistors:
the high grade resistors aren't just more accurate, they are more stable too, ie. smaller temperature coefficent. When your amp heats up the temp changes, high grade R's will change less, this can be important to some circuits.

Also high grade resistors might have less thermocouple effects. A voltage can be generated when both ends of the resistor are not at the same temp, high grade metal films have lesser such effect than cheap carbon film stuff. The voltage (count as a DC offset), if at the input end, will be multiplied at the output. This might or might not be a problem, depending on how much DC offset is acceptable and how much temp difference the resistor's end sees. (this is one reason why vertical mounting of resistor is not recommanded in precision circuits -- the lower end will always be cooler than the top end).

I am not sure if hand matching lower grade resistors will have the above benefits associated with high grade metal film.......

I am talking about high grade resistors like the ones I've used before: Dales, Kiwames, Mills and others...

If you use resistors from the same batch, it's highly unlikely you will run into trouble using unmatched 1% resistors. But in case you hadn't noticed, audiophiles do tend to obsess.
