@billandsol Yes, the Euphoria is absolutely better than the UEF 3.
I have “graduated myself” over the years from UEF Level 2 to 3 to 4, then to Euphoria and now Galileo SX. The UEF Level 3 is very good for the money, but if you can swing it, I find Level 4 to be even better for not much more money. It is less restrained, paints with more texture, and sounds more natural overall. The Euphoria improves upon this even more, but at a higher price difference. The Galileo series is just incredible in terms of ultimate resolution and body, but of course at a cost.
I highly recommend upgrading from the UEF Level 3 to help realize the full potential of your electronics.
