Make a $20,000 improvement to your system for around a tenth the cost. Bybee Technologies has been doing this for years through noise reduction. Prepare to be amazed! Simply connect the speaker bullets between your speaker cable ends and your speakers, and you will probably stay up all night listening.There is simply only one way to understand what these bullets do: TRY THEM! If you are not blown away, initiate their return within the 10 day audition period for a no-questions asked refund.The pinnacle of sonic performance from Bybee Technologies is achieved by combining nanotube quantum purifiers with a proprietary wire network. Technologies combine synergistically to provide noise reduction and dispersive delay correction. Quite simply, these are the best speaker bullets ever made. Sadly, the cost of materials and labor to produce these beauties is prohibitive, so they are available on a limited basis only. Take advantage of the concessionary pricing and a 10 day no-risk auditioning period. When you hear for yourself what they do to soundstage, bloom, decay, upper-end sweetness, and snap, you will probably be spoiled. See the September 2007 Stereo Times issue where Clement Perry gives this product "Most Wanted Component Award." Also see Bob Levi's article in Positive Feedback issue 56 called "The Next Ten Very Best High-End Audio Accessories, but Not Necessarily the Most Expensive." The items depicted have banana connectors. Some spade connector sets are available; please specify spade in your email when ordering if you want spade. I am selling the Speaker Bullets for $2200 per set (PayPal users add $64 US, $86 international)...this is a very limited time offer - once the inventory is sold their will be no more. I secured the remaining limited stock from Jack Bybee for my technical services related to the new Bybee Labs MusicRails.
