I've looked at the Gustard H10 before as well and i looks like a solid amp.. I do want to delve into balanced cables though, where do you get custom ones that are either braided and flexible and not as heavy? Massdrop actually has some balanced cables from Venture Electronics now that I'm considering for the HD6XX and Hifi 4XX. I'm also looking at the schiit Jotunheim amp. So many choices!
