Balanced (XLR) interconnects using the DH Labs for Connex BL-AG balanced 23awg solid core silver wire, which is insulated in foamed teflon having a very low dielectric constant. This bulk cable makes great interconnects easily matching much more expensive cables. This pair uses the very good Furutech FP-701 M(G) XLR connectors. These cables are 3 feet long. http://www.partsconnexion.com/wire_interc_connex.html http://www.partsconnexion.com/prod_pdf/ftech_71065.pdf While these are DIY cables, they are very well made using solid core silver bulk cable (which is much more uniformily constructed than typical hook-up wire based DIY efforts) and very good connectors. You would pay considerably more for anything close to this quality.
