I happen to be one of those reviewers who found, and continue to find, the EX-M1+ to be a wonderful component, to have excellent build quality, and to have additional value in the flexibility of having 3 operating modes. I use the unit I purchased after review on a regular basis, and it has excellent sound quality. I also wrote about the bonus factor of rolling into it discrete opamps, which elevated the performance more, and which, imo, boosts the value significantly.
