Well, then I think you missed out. The LCD-XCs sound great out of my iDevices or portable amp alone, but I would hardly say that I get anywhere close to what I'm hearing with my GS-X Mk2 / BDA-2 combo.
FWIW, the 15% restocking fee is totally understandable IMO. Keeps the "I just wanna try it crowd and then return it" crowd.
I am agree With MH , LCD XC as demo unit i heard With Alo studio Six , than i heard With My portable set Up like what i have posted In previous page.
And now For My brand New LCD XC i use IPhone 5s + Theorem = sound quality is very Good .
With iPhone 4s + Class solo original + Duet
