i recently a got headphone with a 1/4 inch termination. the problem is that my amp has a 1/8 inch jack. instead of purchasing a grado or sennheiser adaptor or one that is two pieces like this one

i got a cheapo ratshack one, much like this one

here is a picture of the set up

anyways, my concern is that the jack on the amp is getting too much stress. is there so much stress that i could damage my beloved pa2v2?
although its not pretty, i'm using some rubber bands on the termination like this

not pretty, but who do i have to impress?
