I’m not sure that the question you’re asking is going to get the response you are looking for. The challenge I see is a matter of definition, what you mean by hi-fi and what I mean by hi-fi may be very different.
To me, hi-fi indicates a speaker that in an upper echelon and can produce a level of clarity and sound that it well above the average speaker. Where hi-for starts is debatable and there is no clear line, especially when you start including used/vintage/discontinued gear but I think it is probably in the ~$2k range for a set of new speakers. Again, this is a general statement that could benefit from qualifying statements about used gear, vintage gear, preference, etc. but it reflects my belief.
For me, the better question is are the audiophile speakers. Here again we run into the issue of what I mean by audiophile is going to be different that what someone else means. Many people treat audiophile like I treat hi-if, meaning speakers have reached a certain high level of performance. For me, audiophile indicates the speaker performs well relative to its price and is something that an audiophile would enjoy.
(I define an audiophile as someone who enjoys listening to music more than the average person and appreciates the improvements that higher quality gear makes in the listening experience. This doesn’t mean that they have or use “hi-if” gear, just that they recognize the improvements that can be made with higher quality components.)
Getting back to your question, I have not heard an Edifier product but like you, I have read a lot of good things about them. I was looking into buying a pair for computer use when I transitioned to working at home. Ultimately, I spent less $ on a smaller set of “computer speakers” as I typically listen through headphones while working.
Based on reviews, I suspect they may be “audiophile” speakers but, IMO, Edifier speakers are not “hi-fi“.
Depending on your goal, you may consider asking something like what are the best powered speakers under $XXX dollars or what is the best small system under $XXX. That said, based on what I have read, if you ended up with a pair of R1280DB’s, you would probably be happy.
Best of luck.
