I listen 30-50 hours a week at work and never get tired. This system is totally non-fatiguing, clean, crisp and clear. No hiss or hum from this vintage amp.

Obviously mid-range is what this is all about. However, the bass will blow your mind due to the 1/4 wave design. Highs are really nice for no tweeter.

I use high def music as much as possible-you can easily hear the difference.
