I got one of these from the Drop sale. My 6XX absolutely loves them, much better detail and clarity than my Atom. However, sometimes when I turn it on, it makes a repeated clicking noise and won't play anything. I can fix this by switching it on and off again. Is this normal or did I get a defective unit? It works perfectly otherwise.
Also, for those recommending the Khadas Tone Board, how do I exactly use it? Since its just exposed circuitry, I'm sketched about handling it. Is there a little box or something I can put it in lol.
