High end audio continues to advance in all tiers. One of my observations has been that really high end stuff tends to remain exceptional for very long periods of time… ten years or more. The other individual issue is how well the product fits your taste. If you have a really good fit, then going around sampling other flavors is going to reveal increased prices and less performance for your tastes.
If on the other hand you are choosing among (and newer / higher tier) other components that are perfectly meeting your tastes you are likely to be really impressed by the progress made..
