Bootman: I guess I could do it with a one 9V JMT, but I doubt that'd be any better.
Dusty: for instance, there is a track on Deee-lite's Sampladelic Relics and Dancehall Oddities (track: "I Had A Dream...") where the deep synth bass starts thumping and a "fweeeeeeeeee" glissando shoots up to heaven from a square-wave/sawtooth-wave synth tone.
First off, the bass was tight and controlled on the Sonys, where it is now woolier and far less refined. Since these in-ears basically cap off your ear canal, this isn't particularly suprising. The Senns are KSC-50-esque, in that their bass tends to overtake the music.
In the "fweeeeeee" glide up, not only can I hear it with more of it's natural body (I am used to being in studios with such classic synths as a Moog modular, a Minimoog, a Prophet 5, an eMu modular, etc.), but I can also hear "into" the timbre of the frequency sweep (by this I mean it is better-described to me, like I could draw the subtleties of the timbre, as opposed to just pretty much hearing the fundamental and the first overtone or two, maybe. The harmonics are far better and more realistically presented).
I'm telling you that I've heard live jazz bass, I've heard, up close and personal, a ton of the actual synths used, directly hooked up to a soundboard, unrecorded, that these studio musicians are using, I've heard a live vocalist in a well-insulated environment and the POS Sony vertical in-ears do a better job of convincing me when it comes to the make-it-or-break-it subtleties than do the HD600s.
Plus, they keep me listening: the Sonys I wanted to keep on (and pretty much every time did) for hours on end. I was consistently being hypnotized, drawn into the music and taken on what literally was like a drug trip. It was engulfing and pleasant.
When I put the Senns on, even after two days of burn-in, after a minute or two, I find myself just taking them off. It's Grado all over again. Unpleasant, not euphonic, not convincing. I'd rather listen to my POS 1990 JVC boombox.
I am going to be bringing in a DVD-A player and whatever better IC's I can get my hands on with the EMP + '600s to see if I can strike some better synergy between components here. If it does sound better, I will also be sure to test it with the Sonys and see if those improved, too, or what.
