They sound thin because they dont get fed enough.

IMHO it isn't quite "thin" though - they still sound right when connected to something like the Recon's integrated amplifier, and they don't really change in tonal character that much. It's more of a bass texture thing, if I had to put a finger on it, but I'm baffled by it because Sony specifically states that this model has a Zobel to *prevent* that very issue from occurring (unfortunately nobody has ever measured them, that I'm aware of, to see what their impedance looks like).

I know that amplifiers that can deliver a lot of power to their headphone outputs, like my Yamaha stereo receiver (it's 100wpc into speaker taps, and it's that tapped through a pair of resistors into the headphone jack), will get along very nicely with them. But I've also encountered some high current opamp designs that do the same thing. They're an odd-duck - on one hand they really don't care about amplifier matching, but on the other hand they do. *shrug*

On a more technical note:
If you're going to build an amp, or experiment with buying amps, make sure whatever design you end up with is absolutely known to be stable into 12 ohms (a lot of designs are not, especially tubed designs - I'd actually even suggest double checking with amp manufacturers before buying a finished product - that 12R is a real killer). I know that most amps on the JR4556 are considered stable there, and I know that the TI TPA6120 is right on the edge of supporting them (I think 8R is it's absolute DNE, but TI suggests 16R and higher - they work very well with TPA6120 devices though). This isn't even really a matter of sensitivity/output, it's just that some amplifiers really can't deal with that low Z safely.

And yeah, I would absolutely say (to anyone) if you have F1s, and like them, hold on to them. They're evidently gone for good now, and they're not something I see on the used market that often either. Truly a once-in-a-lifetime pair of cans. smily_headphones1.gif

I'd say probably a design like the O2.  Anything above ~1.2 ohms of output impedance is going to ruin the sound on that low ohm of a headphone.  One might also try using a (very) low power speaker amp as they have to be stable into far less ohms resistance.

Actually the higher Z not really - you have to remember that output Z influences sound only when you have a very reactive load (DF is an illusion and all that), and the MDR-F1 have a Zobel network that flattens their impedance out and is supposed to keep them very stable (but this has never been externally measured afaik).

A speaker tap would be interesting, but they handle VERY little power (I think it's like 100-200mW channel), and the wiring isn't right for it afaik (I don't think they're 4-conductor inside of the wire, I may be wrong though) - but certainly with a receiver or IA with a headphone jack already built in, what you're saying is absolutely accurate and I entirely second that. I forgot to mention model # for the Yamaha - I have the RX-770, but the modern iteration would be the RX-797 or R-S700 (the A-S1000 or A-S2000 would also be reasonable consideration, but $2500 or thereabouts just to plug the MDR-F1 in is a little wacky imho).

I am currently rocking....nothing!  I am trying desperately to correct this though.  Gonna get me some Grado 325is.

post #321 of 1509

I currently have three in inventory and two that normally get some listening hours in. My main two are Sennheiser HD600 and VSonic GR07 Mk II. Good stuff.

The Objective2 is good but simply runs away at the mention of the MDR-F1. I got one and there,s no way it could ever power those.

 

As obob mentioned, they sound thin with the O2. However they are wacky and a step above the SA5000. Wish Sony would bring back some of its uniqueness and weirdness back.

 

BTW Obob, does the bass lens  really work or just marketing speak?

I personally would just tap the speaker amp into a headphone jack. No reason to go medieval on your headphone cable. Also got to remember that headphone will pull less watts than a speaker due to the higher resistance.

The MDR-MA900 is supposedly their attempt at a "second coming" but I haven't heard them. Might be worth a look.

I haven't ever actually laid hands on the O2, but JDS Labs has said they believe it should be fine with the 12R load (so it will at least be stable; I'm not really talking about "does it sound good" just "will it let the magic smoke out?" right here).

And yes the bass lens really does stuff to the sound - it's a piece of damping in front of the driver that helps to balance out the FR (it will defeat HF and improve LF, by simply inhibiting HF's passthrough). I suspect they would become VERY harsh without it (most headphones with this kind of arrangement do, I've never tried it on the F1), perhaps even becoming more like the SA5000 (which lacks this feature - kind of thinking about it now, wonder what the SA5000 would've sounded like with the lens? hrmmmm).

If the amplifier can handle having -Ve put together like that, sure. Or if it has a headphone jack on it already. Otherwise you're asking for serious smoke and pops (it will destroy the amplifier and probably the headphones). Here's a diagram: http://sound.westhost.com/project100.htm Alternately HiFiMan sells a pre-finished adapter that does the same thing (just checked and it's around $100), and this is basically the same principle behind the headphone output circuit in many full-size amplifiers, receivers, IAs, etc (which means there's no point in re-inventing the wheel here).

Regarding the "headphone will pull less watts due to resistance" [ednote: it should be noted that we're talking about impedance, not resistance, because this is an AC system - but that's neither here nor there] - remember that the MDR-F1 are 12 ohms. With my 85wpc/8R amplifier (as a random example), you'll get around 43W/ch into 16 ohms. They take about .1-2W and then blow up. They don't pull *that much* less power. wink.gif If they were 120ohms it'd be another story. In that scenario you'd only see a few watts maximum out, which is still kill-zone, but you'd probably have some usable range on the volume dial. That specific receiver throws 470R between the amplifiers and the headphone jack - which brings its maximum output down to a safe level for most headphones (I've still blown up cheap stuff with it, just for grins, but the TPA6120 can do that too).


Anyways, right now I'm listening to my RS-1. biggrin.gif

Currently using the M-audio Q40's. Me and my cousin decided to exchange headphones for a week. 

post #326 of 1509

NOTHING. But the 009s are here tomorrow...

Westone 4r, my current portable favorite.

Hey congrats! When's the new amp coming?

 

Looks like my SR009 rig is due to ship out this Thursday. 

post #330 of 1509

They're both coming tomorrow. :D

 

I'm technically borrowing Alex's 009s until mine get here, but it counts because I paid money for them already.
