When I compared the 2 the Rega sounded 'dry' (and it took a long time to load a cd). Between the 2 I would take the SA-10 in a heartbeat. That being said the Esoteric had a lot more detail but when demo-ing it in my home I thought my cd's that were not the best recordings sounded pretty bad (too much poorly recorded detail - very fatiguing) . I prefer musical over detail (actually I like both) and settled on the Meridian G08. If used is a possibility check out the Meridian G06 or G08 (G06 is single ended only & G08 has balanced).
Really you have to decide what sounds best to you and what you can afford.
