Excellent binos - Kahles 10x42 Binoculars

I have a pair of 12-ish year old Kahles 10x42 binos I bought when Bass Pro discontinued this brand. They are great binoculars, but are not quite Swarovski light-gathering, IMO. Not too long after I got these, I compared them next to a similar set of Swaro 10x42s as the sun was setting and after it set. Every couple of minutes both sets would be passed around and the Swaros were the clear winner in light gathering up to and after darkness set. Now, to most this is like splitting hairs because we also had a set of Leupolds and a set of Nikons & both weren't even in the same galaxy as the Kahles' or Swaros'. With regard to clarity, color rendering and "sharpness," these are on par with anything out there, including Swarovski.
