I've had mine upgraded and back from EMM Labs for almost a month. They've been playing 24/7. Similar to the above posts, the new versions sound more organic and relaxed with better dynamics, transparency, depth and imaging. It's a full spectrum improvement and not a subtle difference. When listening, it's now easier to be pulled into the music and not want to get up. There's a dynamic flow and pace to CDs and SACDs that sounds more natural. I listen to a lot of big band and hear the bite of the brass without any stridency. Drums and bass better penetrate the soundstage like they do in a performance. Vocals are clearer and sound more dimensional - front to back and side to side.
As before, the latest EMM gear benefits from top-notch power cords and good isolation. I recently tried The One power cords by Jena Labs and ended up keeping them. They have a very low noise floor, are neutral and dynamic and match well with the transport and dac.
Last comment: it's refreshing to be with a manufacturer that accomodates upgrades, rather than limit customers to a new purchase. I also think the upgrade cost is quite reasonable, given the improvements in performance.
