I’m using a Lexicon MC-8B.
It has phenomenal musicality and it’s preamp section is wonderfully flexible. Mine has XLR abilities. I’m matching it with a multichannel Bryston amp with older B&W matrix speakers.
It has the ability to take in multi-channel data on its optical inputs so it can still nicely get around HDMI needs for audio, and I just use the video sources direct to the TV.
The Lexicons were very well reviewed and have some incredible modes for multi channel as well as bypass if you want. Other than possibly needing a new PS, which isn’t much or hard fo do, they are awesome. Pyramid in Texas does great service.
