Yes.
The only internal connections that remain are tube sockets.
Several studios' multi- & 2T track analog recorders had every connection from the console to the card edge connector removed. Multi-tracks had a pair of audio channels with all audio IC sockets removed. All other channels had PoS tinned leaf sockets upgraded to HiRel machined gold plated.
When designing electronics, we often start with a hand wired prototype. Getting it into production is often a game of 'beat the demo'.
For sceptics whose ears or heads are full of 's$#@', we built 3 versions once the PCB design was finalized.
- Cheap & Cheerful with standard connectors
- Audiophile production grade with HiRel sockets and premium connectors
- No connections - everything including ICs soldered.
Those with clear ears never had any trouble identifying the prototype and each quality level. We realized that we were largely doing it for ourselves and a tiny minority...
