Dynahi resistor locations

[rellik]

which resistors on the Dynahi amp board would benefit from improved matching, quality, temp coefecient, etc.?

looking to see if some locations are more critical than others

Well, for starters...

You could tightly match the 500 ohm resistors in the constant current sources.
You could tightly match the 100R and 1200R resistors between channels that set the gain.
You could use boutique 20R resistors in the output stage.

You might just want to use RN60C instead of RN60D.
You might want to use 0.1% tolerance resistors or tighter.
Obsessing about matching can be fun, but maddening.
