I've watched many of the GR Research videos. His kit speakers seem to be pretty well designed - several of the youtubers, like NewRecordDay and CheapAudioMan, like his speakers and Amir has tested one of his popular speaker kits (XLS Encore) and found it to be good. He himself shows the frequency response curives so he is not trying to hide anything.
Danny also does measurements of other people's speakers, designs new crossovers to address issues, and shows the measurements with his crossovers. He seems to know what he is doing with crossover design as its hard to argue when he show the before and after frequency response curves.
In terms of capacitors, other companies (e.g., CSS Audio) also offer capacitor upgrades. I don't know whether capacitors make an audible difference or not. The YouTube reviewers I mentioned claim to be able to hear differences. One thing I do know is that crappy capacitors are prone to failure. I had a KEF 10" sub that stopped working. When I googled it, I found that one of the cheap capacitors was prone to failure. After I replaced it, the sub has worked fine. Danny at GR also goes on about his tube connectors. I agree that a good connection is needed but I think existing methods like bare wire or banana plugs are adequate. He gets a bad rap mostly for pushing his tube connectors but that doesn't mean the speakers he has designed are bad - they seem to be quite good, as are his crossover upgrades. This forum is about using scientific methods to review audio and so hard to argue when Danny shows the frequency response curves. Like everything else on the internet, take him with a grain of salt, but overall he does seem to know what he is doing.
