The SLC's are very nice, but they are not quite top tier "Alpha" glass. If you want true Alpha glass as per the thread title, I would suggest you have a look at one of the "Big 3"

I currently own the Leica Noctivid 10x42 binoculars and the view is absolutely amazing. Even better than Swarovski EL SV in my opinion because the Noctivid can deliver every bit as good resolution and low light performance, but do it all with better color contrast. Weight balance is so perfect on the Noctivid that I often forget I am holding 30 oz. of weight in my hands. The Noctivid is very compact, focus is super smooth and precise, and it uses an open dual hinge design (same as Swaro EL) that feels great in the hand. No complaints whatsoever.
