Black PEEK--With C-ring made of virgin PEEK, these "specialty" Damping Instruments deliver a dynamic, full-bodied sound; with natural timbre and powerful dynamics. Adds midrange "beef" to lean or thin-sounding systems; particularly effective with audio systems suffering from high-pitch glare. PEEK damping instruments can help "tune" the audio system: placing them around the middle of tubes brings out a deeper, more full-bodied sound; placement nearer the top gives a lighter, more "airy" result (effect will vary from one system to another). Use with any kind of vacuum tube.
