PEEK Damping Instruments: dynamic punch!
![]() PEEK HAL-O 27 |
Black PEEK--With C-ring made of
virgin PEEK, these Damping Instruments deliver a dynamic,
full-bodied sound; with natural timbre and powerful
dynamics. Adds midrange/bottom end "beef" to
lean or thin-sounding systems. 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. For continuous use with tubes operating up to 480°.F (250°.C). A note about price: Original prices for PEEK damping instruments were very high because the material is so expensive. Each PEEK C-ring is machined from solid billet, resulting in very high material usage and low yield. Present prices are below cost simply to recover some of the original investment in material. With the introduction of titanium UltraSonic Damping Instruments in 2007, PEEK Damping Instruments were displaced as Herbie's top-of-the-line product. Nevertheless, these are great, premium-quality damping instruments priced at tremendous value! |
