The plug has all the attributes that i'm looking for, the most important being the PTFE insulation and the direct silver plating. The surprise came when i compared it with the VIBORG VR106G which has solid silver contacts and costs four times the price of the Elecaudio. To my detailed system (costing 15.000€ that are spent very carefuly) their sound is indistiguisable. This is an exceptionaly good sounding RCA plug, which is allso very well made and, to my knowledge, with the highest value/money ratio.
