Is Audioquest Emerald still a good cable?


Using a pair of 20 year old Audioquest Emerald interconnects from my Audible Illusions preamp to my Arcam 27 cd player. In its day, Emerald was considered a decent interconnect. Has technology improved to the point that I need to consider replacing it with something affordable like Nordost Blue Heaven?

friend still runs same cables,keep them,you would go backwards with nordost blue heaven,try looking into power cords
Does it still conduct electricity? Does it still have its insulation jacket intact? Do the plugs make proper contact? Is it still long enough to go from point A to point B?

The rest is keeping up with the Audio Jones of this world.
