What in your mind represents real technological advancement.


To be a real advancement the technology must improve the sound quality. Just extending the bass or the high end can't be call an advancement if it doesn't sound better. If the bass goes " lower " but is muddy or the highs go higher but are " bright and forward and irritating " then that does not improve the listening experience. So the question is what improvements make a speaker more enjoyable to listen to.

mqa? dsp in loudspeakers isn't really new Meridian has been doing it awhile. Making it affordable now that's new.

I would add that the 5g networks and ever increasing bandwidth/ data transfer of digital information will allow easy streaming of large volumes of information/data. MQA gets around this a bit, but once this happens full uncompressed music of the highest resolution will be streamed. Heck very few new automobiles offer CD players because of streaming and I think that will be the wave of the next decade.

That is an excellent thought and I think along with higher bandwidth one could not argue that the sound quality would not be improved...
