I haven't been in this thread for a while, I must say that I feel some people are too paranoid about the heat generated by the mojo...
Probably, heat will be a bit more an issue in the summer when ambient temp is 30 degrees, probably not in the UK though . Lets all agree to reconvene in 10 years and compare notes.
I don't agree with the argument that something new will come along and make the Mojo obsolete, for me the Mojo is the endgame portable DAC (unless Mojo mkII is released)
