Thanks for that, Josie. A very thorough reply, I appreciate that it's very tricky to make definitive statements on audio gear where there is so much that is subjective.

I do like the sound of a big fat bottom end, though I am slightly concerned that it might be too much for me. My equipment is much smaller than 15 inches.

Anyway, best to wait and see what people think about this DAC once the wrinkles are all ironed out!
