6 foot length Silver 9 AWG Bi-wire Speaker Cables; Teflon Insulation;
TST Copper Spades (Amp end) to TST Bananas (Speaker end). I bought these from Mark Tunis who sells his unique handmade cables on Audiogon (user name "marktunis") for use with older model Vandersteen 2C speakers which required the bi-wire bananas and I was truly surprised and impressed at just how much performance they provided for the money; I have since sold the Vandy speakers and no longer need these cables. My asking price INCLUDES Paypal & shipping in the continental 48 states. Mark has a 100% rating with 144 transactions for selling his cables on Audiogon over the past 12 months (274 all time); here is a link to his Audiogon feedback page: https://www.audiogon.com/users/marktunis/feedbacks I'm also including an Info Link URL below to an "audiophile-musings" blog which provides some more detailed and in-depth info about Mark and very positive impressions of his cables following a meeting of the (Florida) Suncoast Audiophile Society. Please feel free to also check my feedback as well, both here and at Audiogon ("Soberdude"). If you have any questions about these cables please let me know and I'll do my best to discuss my experience and what I know about them; in the meantime the following info about these cables was provided by Mark; (yes it is often very "dense" and sometimes redundant but here it is nonetheless): 4 Runs of 12 AWG Silver Plated pure copper, American Mil-spec Aircraft wire per channel; 8 Runs Total Silver-plated copper with 40 microinches minimum coating thickness. Stranding 133/25. The wire is MIL spec aerospace stranded silver plated copper wire, silver being the best conductor of electricity. This configuration provides incredible imaging and detail across the entire audio spectrum, deep, tight, powerful bass, sweet transparent midrange smooth and linear high frequency response.This cable provides incredibly low resistance. Insulation Material: Teflon (PTFE) insulation as a thin light weight dielectric is very close to air, resulting in very low capacitance which makes the cable suitable for any audio component as it will not contribute to instability, or absorb the signal. This cable is very large gauge but will not stress the jacks on your components. The materials (Silver and Teflon) and the labor-intensive processes, both are costly. TST Red copper Spades/Bananas combo: The TST "Tensioned Split Tube" Banana Plugs feature a solid color coded silicone elastomeric tensioning element. This tensioning element provides the spring force required to enable the use of soft high conductivity copper. Traditional banana plug designs rely on the inherent spring force of harder low conductivity copper alloys to provide the required contact pressure to make the banana plug connection. Unfortunately, the copper alloys that have sufficient inherent spring tension also suffer from poor conductivity. The simple and effective design approach of the Tensioned Split Tube (TST) Banana allows our connector to be constructed of C14500 Tellurium 93% IACS Copper. Maximized Signal Conductivity: The Sized Right, Maximized Contact Area and Optimized Contact Pressure features of the TST Banana plugs are significant factors in maximizing signal conductivity but there are other significant factors to consider as well. • Solid Single Piece Conductive Path: The TST line of banana speaker wire connectors are designed to have a single continuous conductive path from the wire to the end of the plug. This eliminates the added contact resistance associated with the common multi-piece design. • Truly High Conductive Core Materials: The TST Bananas utilize C14500 Tellurium 93% IACS Copper and the SP series spades utilize C11000 100% IACS Copper which are the highest conductivity coppers available for their respective designs. Materials like C36000 Brass, C54400 Phosphor Bronze, C17500 Beryllium Copper are the typical copper alloys used and all have low conductivities in the range of 19% to 40% IACS. Bare Copper Non-Plated Connectors: The use of bare non-plated copper connectors provides the natural high conductivity connection of a bare speaker cable termination without the safety hazard of shorting wire strands. Bare electronic grade copper will not turn green or oxidize heavily under normal conditions and some simple handling practices will keep you copper looking and performing quite well for many years.
