Just listened to some Fostex T50RPs today... WOW! - Page 78

post #1156 of 10678


I'm also wondering, if anyone knows a better alternative to the stock pads. People were recommending the O2 pads, but that is pretty expensive. Is there maybe a cheaper alternative that provides similar comfort and sound quality? Any different pads suggestions if you are using a smeggy thuderpants?

(I'm also eager to see how modding them would make them sound, but my modding capabilities are "0" so I guess I'm sticking with stock...) redface.gif

Leeperry had some sa-5000 pads that purportedly fit nicely, but I won't have them in hand until next week.  They're leather, and less $$ than the 02 pads.

More than twice as good? Most certainly.

 

12 times better? Definitely not.

 

For me the LCD-2 is much more detailed, precise and natural timbre sounding,  The T50RP on the other hand has a more expansive sound stage.

 

One thing for sure, ever since I got the Fostex (and before the LCD-2 arrived) I have been less inclined to use my other headphones (HD580, DT800/600).

 

(For comparison calibration purpose, my T50RP is stock).

Well, my CC has been charged so I hope that's a good sign.

That's a large statement!

Wait, what!?  Your T50RP has a larger soundstage than your LCD-2s and they're stock?  That's sure not how I remember the LCD-2s and the soundstage is the T50RP's only real weakness as far as I can tell.

hehe, another proof that we all hear differently and that a "proper" amping goes a long way, because w/ fully closed cups the T50RP SS is really terrible to my ears...and I've got a hard time believing that a T50RP w/ fully closed wooden cups would provide the same stunning 3D SS/creamy mids as the CD3K, let alone the mighty R10. There's a compromise to be made between isolation and SS, you can't quite get both.

 

I plan on trying the SRH840 earpads anytime soon, I'm not sure about the stock felt but I can always ditch it. They're not leather but they're cheap enough to ditch them every 6 months when they start flaking...I just dunno if they're comfy, so we'll see. I very much fancy the idea of having several T50RP's w/ different earpads and cups configurations...like one w/ the sa5k earpads and the side vents removed, and another w/ the SRH840 earpads and the top fake vents fully dremel'ed. Those drivers have too much potential to pass up, and the more they breathe the more amazing they sound IME.

Well, it all has to do with the mods.  I've managed to improve the soundstage on mine somewhat by angling the pads and lining the back of the cups with different felts while keeping the vent unblocked, but I've only mass loaded the back of the baffle with blutak and not something like the newplast you're using and I don't have any of that Akasa foam either.  In addition, the front of the baffle and inside of the cups are covered in dynamat.  I'm hopeful I'll be able to give my pair more soundstage like you did with yours but lyramax said his were completely stock which makes no sense to me.

 

Do these just need more power or something?  It doesn't really sound like it to me though.  Even on my Total Bithead the bass is strong and defined and I don't hear any distortion creeping into the mids or treble either.  The size of soundstage doesn't really seem to change on any of my other amps either.

 

I agree that its rather "3D."  Imaging and depth are very good, but the space they occupy just isn't that large. Its rather like my SE530s.  Amazing imaging in a small area.  The T50RPs have a larger stage than the SE530s but they also have a very "closed-in" feeling at the same time which makes the SS seem worse than it actually is if you aren't concentrating on it.  The kicker is that the SE530s don't have that same feeling despite being far more physically closed in!

 

Does that Akasa foam really help that much?  Will it be a night and day difference?

post #1164 of 10678

Output power is just a part of the equation, not even half of the story from what I gather.  The people in the DIY forum or the Lovely Cube thread can tell you more about amping.

IME:

-angled earpads provide a very convincing 3D SS, that's the trade secret of all the best phones: cd3k, r10, hd800, t1, k1k, you name it.
-amping volume is not what matters...I'd advise to get something w/ rollable opamps, and you'll get my drift. My currently fav. chip on the T50RP is OPA1641, the SS is simply mind blowing. Try AD797B to get a good taste of what a 3D SS means, as majkel wrote here: http://www.head-fi.org/forums/f6/audio-gd-discrete-op-amps-reviewed-OPA-earth-OPA-moon-OPA-sun-v-2-a-397691/
 

I don't really like AD797B, but its SS is business.

 

-the Akasa allows you to hear the original "ambience" of the record, you're not listening to the cups anymore.

Well, the Darth woodies are not too cost effective to put it nicely...you can polish a DT770/Pro80 driver as much as you like, it'll still sound like ---- in the end. No audiophool magic can help, even if you summon the forest gods really hard(and drain your customers wallet just as hard). And I've seen what's being used to damp the large cups darth's: just a bunch of cotton balls...rocket science, eh.

As I already wrote, I tried really hard to keep the stock felt before the drivers but that's a no-go. It simply digs a major dip around 2.5kHz to my ears.

 

I only put Akasa at the back of the cups, I didn't put any on the "curved" peripheral section that's in contact w/ the baffle...not sure whether that'd matter. I plan on trying to put some in there at some point, but this phone just makes me really really lazy coz each improvement upstream pays in cash...and I don't think that I've reached its top potential yet. I must be standing in the 80/85% region atm.

Ok, so where can I get those chips on appropriate adapters.  I'm too ham fisted to solder anything that tiny to browdog/whitecat adapters myself.

post #1167 of 10678

OK then.  I think I'm closing in on a solution.  I think its a bit of both the power issue and the cup reflection issue.

 

Power Issue:  I'm running my signal through my Bithead for the crossfeed processing and into my stronger Maverick D1 for final amplification and the soundstage is much better, but not quite where I want it because of the the...

 

Reflection Issue:  The mids sound like they're originating  from outside the cups but the highs, especially cymbals, feel very inside the cups.  I think this is because all the treble is reflection off the dynamat I've lined the back of the cups with despite all the felt inbetween, which is a shame, since the dynamat did wonders for the mids and bass.  I'm hoping that the Akasa will be the solution to this problem.

 

I'm also thinking that the XM6 might be a good solution to the power and soundstaging issues.  Its got adjustable active crossfeed and rollable opamps and output buffers with over a watt of output power.  It might make a good amp for both home and portable use which would let me sell off some gear and consolidate.

post #1168 of 10678

ok, so I took all of the michaels foam out of the back and filled in the holes (that I drilled) with plasticine, and covered the back with plasticine. verdict: better than before, but I really need proper amping and a proper DAC before anything begins showing itself too much, just ordered a udac-2 (without the coaxial and rca out, 30 dollars is alot right now) on an impulse buy, we will see if I end up regretting it :D 

 

on another note, one of the wires came off the soldering while I was modding, soldered it back in, but it has a slight buzz at certain high-freqs, not sure if I displaced something or if it is because of something else

 

EDIT: I have put little dimples into the thin layer of plasticine on the back of the cups, it increases the soundstage tremendously, I dont think I really need to do any more modding right now, they sound good as is, cant wait for the meet so I can compare them to other ppls modded t50rps.

I have decided to put my T50RP up for sale. From playing around with it I got it to sound very reasonable (newplast, akasa recipe), but in the end I don't like them enough and I don't think they will ever replace my modded (closed) DT880s.

@leeperry

 

Have you tried the 840 pads yet?
