Thanks for the welcome. I've been lurking for a few weeks but had trouble signing up here (the sigh-up confirmation e-mail was not coming through). I thought I had read some earlier answer about DSD/DoP upthread, but the forum search engine does not permit searching on just 3-letter strings--and I got bored doing a Cmd-F on each page to find the reference after 10 pages did not stumble upon. Fantastic! I will give it a try! Many thanks. By the way, the Mercury really responds to a great power supply. And it is shocking how different different HDMI cables can sound for I2S.
