I remain impressed on Day 2. Silky. I've spent the evening listening to my current favorites and I like what I'm hearing.
Mercid, I used the 325s most of the evening. Mine have the flat pads and I've never considered them 'bright'. That could be because I primarily listen to R/B, Funk, and Hip-hop. But, whatever you listen to if you like detail, separation, articulate bass, a deep and wide soundstage and all the emotion of the singer and instruments - you'll like this amp.
The bass is deep. It has punch and seems to move the air in the earpieces, and it isn't just a big blob dropped on you-it has texture. It wasn't a blob before the mod, but it's even clearer now. I've got to listen to some kettle drums roll! The Tower of Power horn section sounds fantastic. Drums deliver not only the initial hit, but the echo/resonance that follows. Guitars are present with all their twangs and the finger moving sounds. Everything is just clearer.
I haven't heard the Ear+ so I can't do any comparisons and I'm not real good at that anyway. I don't think you can go wrong with Kurt's mod on the Corda though. I'm certainly not regretting it.
