Retro HiFi - The Missing Link

This is a video about two HiFi components that could do with making a comeback.
The video features two devices, The first is the Realistic APM-200 - an external add-on VU meter sold in the 1970s & 1980s through Radioshack and Tandy. The main subject of the video though is the Onkyo U30 - an RCA Switchbox/Pre-amp.
I really don't see why an enterprising manufacturer couldn't bring back either one or both of these types of devices. If they were to go a step further and add in a DAC, then we'd really have an handy all-in-one HiFi component. Perhaps I've just given someone the idea for a Kickstarter.
