Just got my 'silver' 325i's. (I can't imagine gold vs silver is such a big deal...)

Obviously, they're not broken in yet but it definitely has a different signature vs the Beyers. Highs and mids are more forward, bass isn't as prevalent as the DT770's. Yeah, I can see where these are more suited to my preference of the Axiom sound. I wouldn't necessarily say it's better or worse in comparison, just different.

Surprisingly enough, I like the Grados matched w/ the Little Dot I+ and Sylvania Gold 408A's vs the Rotel's output. It's not a huge difference, only subtle, but enough for me to prefer it. That was a surprise. I want to compare my Sophia but I need to buy an adapter since the Grados only have the larger connector.

My Beyers may be going up for sale. \:\)
