I tried the JJs and the Ruby's since....neither had the clarity and the low end tightness of the Gold Lions....I heartily recommend them.
Here's my preference
Gold Lion >> Ruby > JJ.
There wasn't much to chose between the JJ and the Ruby..the JJ had a more boomy low end and not so detailed highs....the Ruby might have even been made in the same factory as the JJ but of the pairs I had, it was clearly better sounding.
If you pick up some Gold Lions and decide they're not for you...gimme a shout..I'd rather have them over any other I've tried so far.
