I watched the review as soon as I read your post. I cant help but to smile because his excitement on the DA9 was the same as mine when I made my test. I watched the video from start to end and I enjoyed it. Thanks for sharing.
PS: The SMSL VMV Class A amp brochure you provided is cool. Thanks.
Not sure why this is important to someone who already owns a DA9. Are you looking for validation? From my perspective, if I own something, I either like it or I dont. I dont need someone else telling me if it is a good product.
