“Whether you are listening to an operatic soprano, a jazz voice, soul, blues or rock – each of the really great voices gets directly under the skin. The excellent Audeze LCD 4 acts like the tip of the injection needle at a subcutaneous injection.”

“In comparison to various other headphone amplifiers, with which I tried the LSD 4, the sound of the NuForce seems somewhat more compact, not in the sense of closeness, but rather more concentrated. Overall you really feel reminded of the sound of a very good single-ended tube amp. This combination is certainly not for everyone, but for those who like this type of music playback, they are guaranteed to be highly thrilled.”
