Pairing is another factor though. The 400i with my Asgard 2 is actually pretty good. Not really peaky at all and has a much better low end compared to my EL amp. The EL amp is a bad pairing with the 400i, and the hd6xx is better with the El amp and not as good with the Asgard 2. This is just my taste though. The Hd6xx is just too grainy and hazy with the asgard, but the 400i is clean and smooth. I actually would be able to live with this pair even without eq. I'm just wondering what would be smooth and warm with the Focal. Maybe the THX? For some reason I think the Asgard 2 is out. It seems to only pair great with planars. Both th LCD2C and 400i work best with the Asgard 2 imo. But the Hd6xx and LCD2C both sound great on the THX. So does the 400i with thx, but not as good as Asgard without eq.
