Well - I'm late to the party, but the Surround Master arrived in the mail today. Just in time for my COVID diagnosis and a week or two to work at home. I've only gotten into the SQ vinyl of Jeff Beck Group, and the obligatory "Chase." It is working super well with my Little Bear tube preamp, and I was able to dust off my backup Yamaha AVR with the multichannel input. Finally, a poor-man's setup to listen to all this vinyl on the fly! Put an HDMI out on this thing, and I'm in.
