I have some ancient speakers that when working I have no need to better. Ove the passed 10 years they fail more frequently and have spent longer in for repairs. So I got some replacements and then two more so I have a working 5.1 system. These are also old and beginning to need fixes.
So I set out to get more modern speakers and hopefully not of worse quality.
I tried some life style speakers. Wireless streaming DSP active speakers. They impressed me by the high quality and for most of the time a good enough replacement for my floor standing big box speakers but in a more compact form. But they have poor latency and so watching TV, movies or YouTube using them is not good. I did have the chance to experiment with Bluetooth, Airplay 2 and wi-fi (DNLA) from a computer to them with a noticable improvement of wi-fi over both Airplay and Bluetooth (same wave file as source).
To resolve the connection to play back movies I went from the £3K pair to £14500 speakers that have WiSA (low latency wireless) and also the same wi-fi Airplay and Bluetooth as the smaller less expensive speakers. The bigger speakers are better, a tiny amount better and not anything like £11k better. A huge disappointment and all the reviewers seem to have no clue. Then the WiSA transmitter arrived. This turned them into a completely different speaker fuller, more low end, better stage and almost worth the difference in retail price (I got them second hand for 50% of the then retail price, 12 month sold).
They are still not better than my 45 year old speakers, different, as good, maybe. But I can live with them and that is all that matters.
I think selecting your choice is harder now than ever. Audio memory is poor. You can't walk into one demo and then go across town to another demo and make any real sensible distinctions between two high quality systems. Even side by size one may be better with some music but not on all choices. Fewer places can offer any A/B comparisons as they do not stock the models and can't order them in for a demo with just a potential sale of just one of system.
At the ultra high end I would always short list Linn, Naim, Meridian, some Dynaaudio, Dali and Kii and am still tempted to get in to test Buchardt speakers to hear if they really are 17-40kHz and the Cabasse The Pearl Pelegrina Wireless Speaker 10-27KHz when most are more likely to be 30/40-23kHz.
