I bought these from The Cable Company in 2011 because my speakers, Green Mountain Audio Continuums, use Audio Magic internal wiring, and the designer recommended them.
Now I have a new stereo configuration in a new house, and it requires much longer runs of speaker cables, so these must go.
These are 92" (7' 8") in length and have removable spade connectors. Removing them reveals banana plug connectors.
I think these cables do a wonderful job keeping all the different instruments separated, and they seem to provide a faster attack, making percussion instruments more realistic. However, speaker cable performance is extremely subjective, so I can't say they'll do wonders for your system. They worked great in mine for over a decade. FWIW, my system consists of an Audio Research integrated amp (VSi60), a Meridian G-08 CD player, a Mac Mini running through a Meridian Explorer2 USB DAC, and the aforementioned speakers.
They are a little dusty from their 11 years of use, but they are undamaged and sound as good as ever.
Audio Magic advertised that these are "handcraft silver audio cables", as it says on the box.
Original Box included.
Please let me know if you have any questions & thanks for looking!
