WOW I got my YH-2's today and they sound very very good. I love the signature...It's the best... ..much bigger soundstage, smoother sound, a lot more bass... tight and controlled.. punchy...mids are full... the treble is mellow... Quite nice indeed.
Now are there any good mods I can do to these?
Hee hee. Where else but on HF would you find a string of superlatives followed by that question? Emphasis added by yrs trly.
ZX, I was scanning your post to find what you
didn't like about the YH-2 so we could zero in on the first necessary mod. Sadly, you
like the 'phone, leaving us with no opening move. But verily I say to you that the day will come when you will whip the YH-2 off your head and mutter something like " What the #$% ? there's something wrong -- " Your ears will refuse to stay uneducated and they will start sending little alarm messages along with the music.
If you've been browsing in the thread, you'll have soaked up the idea that this type of headphone, typified by 'phones like the Yamaha HP/YH-2, is deceptive. Everything seems nice and smooth and harmless at first. Gradually, though, you become aware that this 'phone and others like it tend toward an overripe autumnal mellowness. That is, the bass is moderately underdamped and thus opaque and inarticulate. Luckily for us, a bass resonance can be tightened up with a simple shock absorber in the form of an acoustic resistance (say, some nice felt) pressed firmly against the back of the driver, often with a disc of stiff open-cell foam. Once the driver's main peccadillo is smoothed out, you can go about correcting other sins, eg the high reflectivity of the driver cups' interiors, which means either fiberglass or more felt or both. From there you can move on to joint-airtightness tweaks, earpad tweaks, enclosure-damping tweaks and yes, even cable tweaks. It's difficult to say where you'll end up. It mostly depends on how bothered you are by the various imperfections of a headphone driver trying to operate in an enclosure not entirely sympathetic to its needs.
In short, you've got to get mad. You need to stand up and yell at the YH-2 that you're fed up with now-obvious imperfections and you're not going to take it anymore. This won't happen during the honeymoon, which is the way of the world, so we'll wait until the nice wears off and you're ready to peel earpads back in anger.

Hey guys, I messaged the seller of the SFI's, and s/he said they're bipoles.
If he/she knows what she/they're talking about, this is good news indeed. Which seller is it?
i think that those Telefunkens might be the ones i had and sell here on Head-Fi
