Disappointing as it sounds, generally speaking, it has been my experience that hi fi speakers have not improved at all for 30 years or more. There have always been differences between different models, some small and some large and with different manufacturers. Manufacturers today have copied the best designs and components of the past and whilst they might make small changes to the materials used the designs of the components are similar to those used years ago. The manufacturers struggle to make improvements but in order to promote sales they often just change the appearance of the cabinet. They might change the drive unit but it won't sound dissimilar to some made 30 years ago. As I said at the beginning - there are differences in sound, due to size and different manufactures but the reality is the best of the sound 30 years ago has not been improved upon. Yes my stereo speakers are over 30 years old and I decided before I die I would treat myself to some smart looking new ones. Some sounded great in the shops and a friend with me decided on a pair. I was about to follow suit but I didn't want to spend money unnecessarily and so took my speakers to his home. It was remarkable - we could not distinguish the difference between his and mine. His lounge is slightly larger than mine and the speaker placement in his home is better arranged than mine so consequently mine sounded better in his house than mine. I have now made adjustments to my set up at home and have saved a lot of money. Has anyone else come to the same conclusion?
