WHAT TO DO WHEN UNAMPED
Despite its spectacular performance when properly amped, the PS1000 loses a bit of oomph when running naked off my iPod. Initially, I was willing to accept this as a trade-off, especially since none of the other big players I have (the HD800 and T1) are any better when cut off of "life support." The problem, as I've looked into it, is a tonal imbalance. Without the benefit of an amp to push more air, the bass gets overwhelmed by the wider HF dispersion of the jumbo pads. The result is adequate but after enjoying all the thump of these cans amped, it's a little underwhelming.
So, I tried changing out the pads. For portable purposes, I dropped down to the bowls.
Wow!
Bowls cut back on the HF and trap the bass better. As a result, the bass is so strong, it's like plugging these suckers into an amp. In my heart of hearts, I know I could amp them to bigger bass. I also know I could have a wider soundstage. But in the rough and tumble world of portable head-fi, it's just AWESOME!
Now, in fairness to anybody who remembers back to the beginning of this thread, I tried - when I first got these - to do what I'm doing now. They sounded terrible. Pre-burn-in, the sound was just too thick. The bass was excessive. The mids sounded crowded. The resolution just wasn't there. I didn't like it. In fact, I didn't like these cans until I went back to the jumbos. That's when I'd realized how tuned they were to the jumbo sound.
And they still are. But they're also supposed to be amped.
Without amping, with the bass relying solely on what my iPod puts out, it's an amazing return to the center. I'm getting a baby version of what my cans do when they're properly amped, minus a little of that HF extension. The thing is, without amping to also bring up the bass, that HF extension makes these cans an anemic version of what they were meant to be. So, I'll take a little less on the high side - especially since Grados are known for being "bright." The little extra extension is something other headphone lovers hate about Grados.
These slightly "darker" Grados are what other folks call "light" and "bright." So, for portable purposes, the bowls make a tremendous difference - as long as these cans are properly burned in. I'm getting plenty of midrange, plenty of sparkle but an even punch that just rocks my socks off.
I'll be the guy at the Y burning 2,000 calories on the elliptical cross trainer while listening to his oldies.
