Bybee Technologies Crystal Series Plug-in Speaker Bullets.
I’ve been an Audiophile for over 30 years, and one of the most important and critical lessons I’ve learned over the years in high end audio was about the utilization of audio "Tweaks." Specifically, tweaks for my speakers. Some 15 years ago or so, one of my local high end audio dealers introduced me to the Bybee Tech (plug-in) Speaker Bullets (along with other types of tweaks for audio components) and I was absolutely floored by the many ways those babies effected and improved the sound of any pair of speakers, regardless of price. I’ve been using the Bybee speaker bullets every since. Expensive? Yes. But, for me, worth every penny. I found the plug-in variety of speaker bullets to be even more effective in filtering out the noise than the internal ones, so again, I found the plug-ins by Bybee Tech be be the most effective. If you have no experience with these types of fascinating devices, then you just simply have no idea, period. The Bybee speaker bullets are a revelation!!!
