Lurker here coming up to state an opinion. If I'm not mistaken, Antelope Audio consist of some of those formerly involved with Aardvark Audio. Several years ago, Aardvark Audio suddenly, summarily, and with no notice nor warning disappeared, leaving all of their customers with no support nor updated drivers for little things such as, say, Windows XP. Additionally, they did not make available the source codes for users (unlike myself) who are capable of writing new drivers. Hence, my Q10 = useless paperweight. For that reason, I am totally reluctant and unwilling to do business with anyone who was involved with Aardvark Audio, no matter how good their gear purports to be. If I am mistaken, I'd love to be corrected, but I don't believe I am. When dealing with "professional" gear, especially items costing >$1000, I expect long term customer support with no exception, period.
I will not get burned twice.
