Herus does a good job with the K702, though it won't help that headphone for people who don't like the presentation. Sounds like you do so it should be a good match. Tons of detail. I don't really find any particular disadvantage to the Herus in a home situation, other than requiring an adapter cable if I want to connect an external DAC. I can't really think of a $350 unit that I'd rather use.
Thanks for your reply. Now I think I am ready to advance with the purchase :) .. finally!
