This is one excellent cable for low/mid power applications. I use it to connect bass head with my bass cab. 1,5 Sq. mm is very easy for soldering, but more than enough for 500W and more, plus I saved some space and weight compared to the overkill 2,5 sq.mm or even thicker cables.
Due to low diameter (7mm), it will fit most brand name 1/4" jacks (I use Amphenol and Neutrik)
