Just listened to some Fostex T50RPs today... WOW! - Page 698

post #10456 of 10641

Sorry if I'm ignoring everyone's post, but I'm currently using a 3.5mm L shaped cable to 3.5mm (not the stock cable on the t50rp). I read somewhere here on the forum that plugging up the sides of the locking mechanisms will balance out the bass balance issue. It really did! The balance is off by 2-3db starting at 40hz (lowest that I can efficiently hear through the fostex t50rp's), to a mere 1-2db stopping at 120hz. I took the risk of plugging the holes with Crayola Modelling Clay.

Does anyone know which would be the better choice between Fiio Mont Blanc E12 or Alpen E17 to drive modded Fostex ? Or even another portable amp in their price range that can give the mWatts to this hungry can ?

I believe the latest T50RPs actually did get changed/retuned. At least as far as product descriptions go (the descriptions are now different). Haven't had the chance to try one out, not that I have an older stock one to compare it with.

I am not sure how to mod the headphone to sustain this angle and openness though.

Just because you're applying lacquer to the cups won't make them sound more organic per say. Violin's organic sounds are, as you know, not exactly attributed to lacquer. Effect? sure. Can't say if it'll be a big one though, never tried the concept. The plastic isn't all that amazing but it isn't that cheap either.

 

To sustain that angle---angled earpads.

What's wrong with damping though? If you're a fan of speakers, it isn't as if speakers aren't filled either. Though probably not with clay.

 

All roads will not lead to a dull and flat sound. And specially since planar magnetic drivers, the ones without driver back sealed, essentially emit the same amount on both sides, back damping has a lot more effect than your average dynamic 'phones. Notably the sealed/semi-closed ones.

Both would be okay. Ideal or not depends on your mod.

While they do boost extension over stock regular DAP (non-'audiophile' oriented types), which led me to think the E17 had a brighter character to it, they're on the warm side. If warmer works well with your mods or stock T50RP, AND your tastes, they would be okay.

 

The E12 has more power, if ever your concern is that they're hard to push. I can run them fine out of my phone, albeit mine's aren't heavily damped.

Thanks Kalbee, good to know that both (E12+ E17) can drive modded 50's.

I bought a pair of 50's modded already before and they just would not drive off my old altoid tin but my other 400 orthos did work off the altoid so unfortunately at that time, had to return them as I thought they needed monster juice to even work !

Do you mean the HE-400? Those are fairly easy to drive iirc.

 

I mean, my current T50RP mod can be driven by my iPhone at about 50% of max volume setting... at least as far as volume goes. It's the most heavily damped mod I've had till now, but nowhere near the dampening levels of more popular mods from what I hear.

Anywhere between 24~36 (out of max 60) on my E17 without using +12 gain. 9~11 o'clock on my Bispa (with high gain on). 8~10 o'clock on my P-H without high gain off. I know that many high end DAPs don't quite drive modded T50RPs very well, including the Colorfly C4 and A&K AK100/120. I had to practically max volume those for outdoor levels of background noise.

 

Some people will talk about not bringing out the potential/full potential without a good amp---THAT kind of driving power... I have no clue what they want to say because there's always better amps out there that will drive them even "better". It depends on your hearing/ears/tastes and the state of your headphones. The E17 doesn't give me the thin, underpowered sound that the AK100 did so I'd say they're good enough. But, once again, mine weird mod (that needs fixing) isn't all that heavily damped so YMMV. If you want to have a bit more leeway in power, the E12 should serve you well.

Ive lost nearly all my screws..can anyone confirm if any of these are the ones i need?

Ive even had to take some out from the middle 3 screws that hold the driver which im sure is not a good idea

The ones shown in the first link, above, look identical to the stock screws. 

 

Fostex stock screws are 2 mm x 6 mm (tip to Under screw head. They have 7 "threads" like the ones in the first link.

My comment regarding dampening was more tongue in cheek to address the guy who said he lacquered his TV.

 

I did get a pair of Shure pads, and that did cure most of the problems I have with the T50rp.  The sound is still undeniably "plasticky" after getting past the 10 minute mark or so.

 

And, of course lacquering won't make a night and day difference.  What it usually does is change the tone a bit towards what the ear is more used to hearing.  Of course, not all lacquer is the same.  In my experience, applying the lacquer directly to circuit board yielded the greater benefit.  But, I never applied it to speakers or headphones before.  Nor, will I as I think I will be returning these pretty soon.

 

After auditioning many headphones during the past few weeks, I feel it's us that are acclimating to the sound of the electronics.

Anyone had a chance to listen to the Digizoid 2.3 with their modded 50's ?

I believe I did, but with a pair of Mad Dogs not my own. There wasn't any problems per say.

Not sure if headphones are considered electronics but anyway... what you feel is correct. In fact, there is no other way.

If humans and animals alike did not know to adapt, we'd be long extinct. Based on our environments and backgrounds, we're also selectively sensitive (or insensitive) to specific things, just as we'd also have our bias on how things should sound for the better.

 

The T50RP is best known as a inexpensive full-sized planar magnetic headphone. It isn't without flaw, in fact has many, but whether or not you will want to mod it significantly to improve the sound depends on your own volition. Like many have said in the past, there are still limitations to both the drivers and the enclosure, so we're not saying mods can achieve summit-fi tier performance. They also require effort, and sometimes the same time spent working to increase your headphone budget might be of better worth than sticking with these guys. There is no shame in choosing one or the other, or even to prefer the T50RP in their stock form. We do not all see, feel, hear, nor think the same. Our ears both enable us to hear and also acts as a filter unique to oneself.

Did it give a bigger soundstage / instrument separation  as well as a deeper level of bass ?

I see the Digizoid 3 is coming out soon.

On that end... unfortunately I cannot comment. That was the first time I listened to the Mad Dogs so I never got any before/after impressions specific to the Digizoid. You might find better info regarding those aspects in the Digizoid threads! might have T50RP lurkers there too ;)

The bass boost did work very well though.

There is also a dedicated Amp for Mad Dogggzzz thread.

Of course speakers are electronics. 

 

And, a bit off subject, but animals do not adapt in the manner in which you've described.  Evolution doesn't work like that.  Either you got the traits to survive or you don't.  You don't adapt.  Your genes will but you won't. 

 

My volition or opinion on the T50rp is that the enclosure is hopeless no matter what you do with it.  Sure, you can improve it, extend the treble, tame the bass, eq the heck out of it, but, imo, it will never produce music that will satisfy me.  I think the AlphaDog is on the right track of taking the enclosure out of the equation.  But, the enclosure Mr. Speaker is using is plastic too? 

 

Oh wutever the case, I just received a LCD2.  In heaven at the moment.

Lab rats beg to differ but anyway.

 

Hopeless? How far have you modded, or what kind of modded models have you heard? How far do you even know?

You're right though, the original cups are everyone's limitation. No matter what kind of modifications you do to them, you're limited in internal volume and shape as you have found out. There's only so much space to alter the properties of that 'cheap' plastic. In which case a larger enclosure or one with better material properties would alleviate a lot of the headaches.

 

Though honestly the constant nagging of plastic this and that reminds me of people that equally nag about Made in China products. Not all plastics are made equal, just as not all products made in China have the same degree of workmanship, QC, and material quality. And as mentioned, given a proper structure and size, plastic enclosures can have most of their flaws eliminated.
