I have not heard matrix element, but used Lumin T2 in my system for 3-4 months before I upgraded to Luxman D-10x. I thoroughly enjoyed Lumin and if I had to go back, I will be happy to. Very musical and analog sounding. I loved the ease of use with roon. The separation of instruments and soundstage was top notch. You have plenty on sale right now, and you will not regret if you buy it. I believe the reason for lots on sale in used market, is not because they are bad. They are so good, you get itch to upgrade to higher Lumin like S1 or X1. I was about to do that, but went in different route. Good luck.
