Re: is the Eclipse upgrade worth it? It was to me. I bought my Calypso new the year it was released and wanted to send it in for a tune-up. A couple of the solenoid selection switches needed a few pushes to activate. I have always loved this unit, and never considered an alternative. I decided to upgrade it, and assessing the levels of upgrade, I could see no reason not to go to the eclipse. The Calypso always sounded way ahead of it's class, so any noticeable improvement would be a bonus. I certainly did hear improvements - a little more air, transparency, solidity of bass frequencies, sonic images. I wouldn't hesitate to do it again. It would be hard to beat for the same price.
