I'm not overly familiar with this newer Multi EQ X ($200), however have recently used the Multi EQ Editor phone app ($20) after applying numerous of the edits to the standard .ADY file (using REW software) and the incredibly detailed advice that Mr. OCA (Obsessive Compulsive Audiophile) provides on his UTube channel. If Multi EQ X can come even close to the extremely impressive sound that the $20 Multi EQ Editor app + REW + OCA's edit advise provides, then it could be an amazing tool. I'm sure most of you are familiar with OCA as he's been around for a little while, however if you haven't I STRONGLY recommend you check him out, and I will guarantee you'll be impressed!
