Wow, as an obsessive review reader for anything I am looking to purchase, thank you for a great review ClieOS! In-Depth, comprehensive, plenty of pics, simply fantastic.
Anywho, I'm curios if this might be overkill for some AKG 142's that I'm looking at getting. This and the E5 seem to be leading candidates at the moment for a portable amp, and I love that this is also a DAC. Worth the extra $$?
E7 definitely will worth the extra money. The amp section sounds better than E5, plus an DAC gives you an upgrade over onboard sound card. It is a better investment in the long run.
