Beta had a slightly high bandwidth but probably not enough to make a difference. These days you get four channels of 96kHz 20-bit audio in a wee box the size of a Betamax tape, with hours and hours of recording on an SD card. That physical size is mostly a function of needing half a dozen XLR connectors on it and a big enough screen to see what you're doing.
