Funny coincidence, I auditioned the same three and wrote the following:I was able to hear the 2C, the X, and the MM-500 at a store a while back, and the 2C was my favorite of the bunch. MM was too shouty and clamping, X was oddly dark and physically heavy, while the 2C was relaxed and more comfortable. I can only do the following comparison from memory, but I'd probably take the 2C over the CRBN and LCD-5 even. Those two follow the new Audeze tuning which is a bit too midrange-forward for me. The 2C would offer a different yet enjoyable sound compared to my current collection (see signature).
I'm tempted to pick one up, and the store owner said he could give me a discount on it too, but I have a few other headphones vying for my budget at the moment.
I also agree on the LCD-5 (haven’t heard the CRBN).
- The LCD-X and MM-500 being both technically strong had no major issues. Any weakness was either down to the subpar setup or easily fixed with eq. The difference in presentation and cost between the two makes it difficult for me to see a future with the MM-500. IF I was earning money producing music AND in need of a portable ”mixing solution” it would make perfect sense. Otherwise the LCD-X for me. It sounded soo nice with Bob Marley.
- The LCD-2C was just so mellow. It isn’t as resolving as the other two Audeze’s but manages to make it a strength. It couldn’t handle the more dense part of ”No time to die” and it somehow made it feel alright anyway.
PS. The Stax SR-X9000 is very nice
