There are many who pref the 627 over the 627x for this reason. However, doing an A/B test between the two, I don't think the 627x has worse mids, it's just that the presentation is not as midcentric as the 627.
The 627 manages to sound more realistic because of the upfront nature of the mids: as they're recessed on the gen2 the immersion isn't as intimate. But the 627x has that soundstage, so it's a different kind of immersion being achieved, which i prefer.
Cesar upgraded the potentiometer in the gen 2, and it really does sound like a big brother amp to the gen 1. After A/Bing for about 8 hours, I consistently end up switching back to the 627x for extended sessions.

Could I ask how the bass between the two compare? I have a 627 and one aspect that I love about it is the (compared to my other amps) impactful, precise, strong bass it delivers.
