OK, so I played around with the SR-001's some more. Tried a few different positions, a few different tip sizes, and for the hell of it, tried them on the headband and not inserted into the ear canals - just resting on the ears.
And...
HOT DAMN!! It turns out that I was wearing them wrong all along! On the headband, and just lightly resting against the ear canals - not actually shoved down the ear canals - they provide the best performance
and the best comfort! They're actually quite comfortable this way, much better than all my other canalphones!
The sound definitely changed. They're no longer quite as midrange-forward; now they're just plain warm. Very, very warm. There's a lot more bass, and it is excellent in quality. Still too liquid by half, and lacking in resolution next to the SR-404, but much better in terms of impact. And there's slightly too much of it! Never thought I'd hear a positively
bassy electrostat but here it is. The mids are unchanged, but a little less hollow sounding. Right now, they're next to perfect, with one caveat, which I'll get to later. The treble is still rolled off. Using the treble booster on the X5 improves things slightly (I have to use the headphone out, not the lineout for this), but when pushed too far, the treble becomes grainy and scratchy. It's probably the amp's doing, though I'll need to hear the SR-003 on a good amp to be sure.
The main sonic problem now is the same one that I've had on the HD650. There seems to be extra bass on each frequency, in places where it shouldn't be. When listening to piano, you can almost swear that the notes that you know are in a specific octave actually sound like they're an octave below, or at least are lower in register. The pitch is right, detail and tone is right, but the note simply sounds too deep! Real piano doesn't sound like that, at least not to my ears. I've ran into this on the HD650, though not on the HD600, and once again I run into it here. I don't really like it, but it does sound very "nice." It gives everything a layer of extra lushness and warmth that isn't normally there. I guess if you like a warmer sound, you'll love this, but I don't care too much for it, except with some music where it does wonders (try old school mellow psychedelic rock, or some of the newer rock/electronica hybrids).
If I had to make an analogy to what the SR-001 sounds like now:
Imagine yourself sitting in a hazy, smoke-filled room, pleasantly smashed on your substance of choice, surrounded by attractive members of the opposite sex (or same sex if you're into that kinda thing), and listening to an ultra high-end system. You're buzzed, everything is warm and pleasantly glowing. The room is dark, the confines are smoky and hazy, and edges are slightly blurred, but in your pleasant state you can still make out everything that goes on around you.
The SR-001's sound now is kinda like that. The treble is muted and decidedly lacking in energy, so everything sounds very dark and, well, hazy, even though every single ounce of detail is still there. The lower end - bass to midbass to midrange - is so beautifully smooth that it almost sounds like it's smothering you in a blanket of pleasantness. The soundstage is definitely not canalphone-like anymore, it's more of a full-size can thing, though the imaging is, once again, not very precise - it's a bit smoky and diffuse, though not wavery.
Sounds nice, doesn't it? In a colored sort of way. Well, it is. I have a hard time to decide which I want to listen to now, SR-404's or this. I have never before heard such a pleasant combination of detail and warmth, even if I'm not a fan of an overly warm sound.
I expect that once the "new toy" syndrome wears off - and I feel like I've completely rediscovered my SR-001's - I would be qualified to be more objective about them. But for now, I'm in love. Again.
More later
