Nice review. Last night I was listening to Duke Ellington's "Blues in Orbit" CD. The three-dimensional presentation you described was there in spades. The Gate is a phenomenal addition to a serious stereo system. When you get around to it, put a couple of Omega E Mats in the circuit breaker box. That will further enhance the effects.
Here's the CD:
Remember ... there's a 90 day, money back return policy on The Gate if you're not satisfied with the results. To date, I don't believe that anyone has returned one.
