I have two of the Fun amps (different systems). They are in a rotation with various other amps. The Fun is clear, clean, articulate and extended. With some of the better treble (op-amp dependent) at anywhere near the price. Much better lateral spread and instrument separation than many amps. I hate the globs stuck between the ears, with the occasional instrument floater above the forehead. I should also mention that I listen to actual music. Acoustic, simply mic'd in real space, or the orchestra in a hall. Recommended.
