I'm working on PC Part Picker for hi-fi stereo gear. https://buildhifi.com

Some technical highlights:

- Graph-based signal flow: Products become nodes, connections are edges inferred from port compatibility (digital, analog, phono, speaker-level domains)

- Port profile system: Standardized port definitions (direction, domain, connector, channel mode) enable automatic connection inference

- Rule engine: Pluggable rules check completeness, power matching, phono stage requirements, DAC needs, and more

It's getting close. I'll do a show HN on it sometime soon.

This is fun! I put my (slightly oddly setup) system into it but I couldn't reconfigure which set of speakers were connected to which amp, or reorder the signal chain at all. Is this a planned feature? E.g. I have an integrated all-in-one amp that drives my main speakers but I tap off the pre-amp output into a secondary integrated amp that drives two secondary sets of speakers but your app assumed that my second amp was driving all six speakers and so spat out a warning about power levels...

    Thanks for trying it out. I've got the signal chain and messaging handling most setups well. This is pretty novel. I'll see about handling it.

    Do you have a link to this config you would share with me? Use the Share Config at the type right of the builder to get a portable URL anyone can use.
