You have more DMM in your collection that you may realize! Most GZ are DMM, all MOV are DMM, Pirates Press uses DMM and so on...I would avoid Dmm's tbh. I find them thin and tinny. You would be better off with RVG or McMaster Cd's with a good player or dac imho.
With the shortage of pressing equipment, DMM presses are very common in use today.
General rule - if it comes from a lacquer, it cannot be DMM. If it comes from a digital file, it is usually DMM.
