_Note: Sparkos Op Amps are backordered and will ship late February._ If you're running [the Druid R2R DAC](https://apos.audio/products/apos-x-community-druid-r2r-dac?_pos=1&_psq=druid&_ss=e&_v=1.0&variant=46943198707948) and want to hear what it’s truly capable of, this is one of the best upgrades you can make. This fully discrete, 100% Class A op amp drops into standard DIP8 sockets and replaces generic IC op amps with a purpose-built analog stage designed for lower noise, higher linearity, and more stable performance.  * * * This is a companion discussion topic for the original entry at [https://apos.audio/products/sparkos-ss3602-dual-discrete-op-amp](https://apos.audio/products/sparkos-ss3602-dual-discrete-op-amp) ---

I’ve been enjoying my Druid x Gremlin stack w/Apos Ray tubes. Unlike with tubes, which have a measurable and observable effect, I’m a bit hesitant to swap opamps. I know it’s a popular feature to request and there are many who enjoy swapping opamps, I’m just a touch skeptical about it. Any chance there are any measurements or data otherwise that’s available to highlight the potential changes? ---
