Similar recent experience here. I used the tech support email first from their website. Then I followed up about a week later with a phone call (which was last week). Master Lu encouraged me to call. He assured me that the BDA-3s are usually problem free.
Bryston's tech Adam helped me upload and install beta firmware on my BDA-3, to resolve an issue playing DSD files on JRiver MC27 via USB. He stayed with me on the phone as I installed and verified the problem was resolved.
I was hoping Bryston would live up to their reputation here with tech support after the sale. I was not disappointed and happy that I purchased my first Bryston product.
Cheers!
