Just took delivery of an MJ2 w/ LISST + stock tubes this afternoon. Currently paired with Gumby as the balanced in and Mani as the SE input. I've noticed that nobody has posted anything specifically about vinyl as a source with the MJ2 yet on this thread. I can confirm that the Mani + MJ2 combo sounds stunning: warm and holographic even with such limited burn-in, while my previous setup using A2 + Mani sounded harsh, sibilant, and analytical. I had been contemplating upgrading the Ortophon 2MR on my Debut Carbon to get more detail off my vinyl, but hearing my records through the MJ2 (using stock tubes) has me thinking I'll wait. I'm hearing nuanced background details pop out that I've never noticed when using the Asgard 2. Very happy with the performance and can't wait to hear the set-up at its full potential when my LCD-3's arrive and I'll be able to take advantage of the balanced functionality. Also looking forward to evaluating the LISST sound, but for now the stock tubes aren't going anywhere.
Cheers!
