What are these worth?

As Jond says, start an auction. You may get lucky and find someone who thinks they are worth more than $100.

yes an auction would be a good way to get rid of them.

Auction on ebay, not Audiogon. Sell on Agon, but never auction here.

Rsc master was available back in 1993, this model was before the model called decade, the cable you have is very stiff like, this was the young years of Taralabs cables as a company, thou it is 10ft, the sound of that particular cable was terrible!, It has some good traits, bass is not one of them,a little clarity, and decent mid-range,, you know that the length makes it a custom cable as well!, most a/c cables are 4ft to 6 ft, It may be hard to sell a custom cable?, regardless, my opinion is that the cable you have is worth no more than $300.00,, I hope this helped you,, cheers!

Audiolabyrinth,
Thank you...that is exactly what I wanted to know. At this point if I got 100.00 each that would be cool.
