Follow the signal.
A record reaches the room through several stages: cartridge, phono stage, level control, amplification and speakers. A mixer may sit in that chain when selectors blend records.
Neiro publishes its cartridges and preamplifier; Shiru documents a phono stage and rotary mixer. Reading the full chain is more useful than judging the room by its speaker badge.
