The equipment may well improve over time, but it's already so good that the improved versions of electronics will sound no different from current competent equipment. Transducers are a different story, though. Speakers and phono cartridges may well improve over time. Microphones are very good and sit somewhere between speakers & electronics in terms of improvability.Could not disagree more. IMO we entered a new era of audio excellence about 5 years ago and that era is still young with a lot of room for more new innovations.
