I'm not an expert by any means, but I don't really think so. I think hi-fi audio is one of the few fields in which technical development is stagnating or even lagging behind in terms of sound quality. This is probably mainly due to the fact that the quality of streaming files is much poorer than that of lossless formats on data carriers such as CDs anyway. The same probably applies to wireless solutions. Streaming and wireless audio transmission is of course much more user-friendly, but in terms of audio quality it is probably not a step forward.

Old speakers had enormous, heavy magnets and were great at reproducing audio, especially on the low end. The only major "development" with modern speakers has been the ability to sort of reproduce sound with lighter-weight, cheaper materials.
