The term bi-amping gets thrown around a lot these days - often without any understanding.
This sounds more like I couldn’t be bothered.
Like I said an experienced tech would take about an hour to do it and the parts cost are a pair of speaker terminal, I’ve done quite a few in the passed, it’s easy even for someone with basic electronic skills.
And sorry to tell you but they do do it.
