S. Andrea said: What the Masters M51 offers is a sound that’s smooth, laid-back, and always pleasant, no matter what you throw at it. Its slight favoring of the midrange imbues the sound with just a hint of extra warmth. For many listeners, such a combination is a recipe for audio bliss.
Read the SoundStage! Hi-Fi review.
The gist: Unique sound that some, if not all, will find just right.
