Cardas connectors

I've noticed that many companies use Cardas connectors with their cables even though that company might have their own design rca's! Is there a particular reason for this! Does Cardas connectors improve the sound of the cable or is there some other reason to this! Would appreciate your thoughts!
Thanks in advance!
ramesh: cardas manufactures or outsources numerous parts for use by other companies (OEM). these parts are considered by many to be of high quality and design. hence, manufacturers order connectors, wire, etc. from cardas rather than going to the unnecessary expense of designing and building or outsourcing these parts/components themselves. for a listing of OEM parts available from cardas, see:
