Gooey is probably not the best term. So what I meant is that the bass has a bit of bloom in the ear+ and the treble isn't strident. There's a slight bit of warmth as midrange notes have a bit of overhang.
That's less present on the voltage out of the bakoon. Less gooey.
The treble was about the same on the ear and current out. Not harsh, smooth. If there's greater extension on one of the amps, I could not tell. Voltage out is a bit more strident but not a lot. It's not like hooking up the ps1000 to a thin amp like what I hear out of the dc-1 amp. It's just a bit more energy up top. Not much. The bass difference really grabs your attention.
Interesting. I'm a big pro-treble guy, and as such I tend to gravitate towards SS gear, but if the Ear+ has the extension and detail of its high-end SS brethren, I would definitely love to hear one... Thanks for the clarification, man!!
