I had a shoot out between the MM-500 and the LCD-5 as well as the Meze Elite at a Stockholm dealer today. I’m a Grado lover so I came with a (more or less) neutral mindset, attracted to the design and price point of the MM-50.
The MM-50 are going home with me on a loan to see how they compare to my PS2000e. They will be partnered with my new electronics: the Audio Analogue AAdac and the Leben CS600X, an integrated tube amplifier with a higly regarded headphone output.
The Meze Elite I find a little too lush and fabricated sounding. The LCD-5 are a technical tour de force in resolution, extension and smoothness. I however found that MM-50s midrange has a more solid presentation that I preferred, and that the bass aided a very nice intimacy in music. Detail retrival was generally not miles away from the LCD-5, but there is a distance indeed, especially outside the midrange. On all songs I tested I preferred the MM-50 tbh. My taste leans towards alternative pop/rock and singer songwriters.
