Most prices drop a good bit at 10 parts. Still, a big bump in price from ~1cent. They are very conservatively rated—i just sorted through several hundred RN55 and most were tighter than .2% tolerance. I haven’t tested for noise, but my sense is that they are similarly well under the spec ppm. Overkill for pedals, but I’ve never let that stop me. If I can fit them in, I’ll use styrene caps for pf values too…
Wait until you run into projects that involve trimmed foil resistors. My DAC has several Vishay and Caddock foils in it that cost between $18 and $30 each. Unfortunately, the circuit sounds better with them…
