I was thinking about selling some of my headphones, not sure what to sell, but I have been accumulating a lot of stuff and I listen to only some of it. Before I go to the for sale section and list stuff there I wanted to give guys in this thread first dibs. Take a look at my profile and let me know if you see something you like, not everything is for sale but try me

YGPM, and the QP85

EDIT: Dibs on the PMB100 and possibly one of the YHD's :D

ps wualta - keep the opinions comming, I am starting to listen more and more to the recording techniques...

I can't say I recommend listening the way I do, because there's a danger of sucking all the magic out of the recorded music 'sperience. I'll risk repeating myself: as your equipment gets better, recordings will start to sound like recordings. The general assumption that better gear gets you closer to the experience of live music is, sadly, without basis. You know your gear is getting better when you start to hear things that don't make your toes tap (why just the toes?) but rather make you say "Oh.." "Ouch!"  and "Oof, she buried the needles [on the old VU meter] swallowing the mic on that note.." Good gear takes a mix that cost millions of dollars and months of hair-tearing panic to produce, and deftly takes it to bits before your very ears. The producer consoles himself by saying "Heh. They'll never hear that." Then he gets in his Bugatti and drives off, little knowing.
 
The flip side to all this is knowing that if, by some miracle, a really good recording ever does come along, your equipment will be ready.
 
In the meantime, you risk becoming a paraprofessional nitpicker and killjoy. Don't say I didn't warn you.
 
By the way, I'm using a Sony portable CD player optically feeding the Panasonic XR55 which is driving the headphones from its speaker outputs through a Pioneer JB-21 resistive coupler. The Equibit amp inside the XR55 is basically a power DAC. This doesn't mean it's perfect or that everyone will like it, just that the signal stays digital all the way to the speaker terminals, or so they claim.
 
As for the TP, if I were to be a swine nitpicking killjoy ingrate, I'd say the bass needs to be tightened up and/or extended downward a bit (I know, the two are exclusive) and there's a peak in the tizz region around 6--8 kHz that makes female sibilants stand out. That's the kneejerk nitpicking no-social-skills engineer part of my brain talking. But I also know that a closed 'phone is a mess of tradeoffs, and one of the payoffs here is a wonderfully tight mono image, which means it has an ultraclean stereo image. Stuff that in a normal 'phone would get sprayed randomly all over the headstage stays locked in place on the TP, so all the little details come out. This gives the TP its ability to take apart a stereo mix. The treble just seems to go on forever, too-- it doesn't die after the peak, so I'm guessing maybe cavity resonance somewhere in or near the driver? maybe? Anyway, this is what I'm hearing on my equipment. The YH-100 plays lower and tighter, but it sounds rather dry and HD-414ey on the top end compared to the TP (yet another of those tradeoffs) and the mono image isn't nearly so good. Fostex has made great strides in driver matching, it appears.
 
Random hint for the next auditioner: don't let the earpads cover the little brass vents in the bottom of each cup.
 
Smeggy has worked an amazing acoustic tranformation on the stock T50RP, to say nothing of the sheer craftsmanship involved. Which is what we'd expect of him. Those expectations will eventually kill him, as he well knows. I'm grateful for the mere opportunity to sample his cooking. In the meantime, I'm going to try a reverse reflex dot to see if I can't squelch that tizz. "Squelch That Tizz!" would be a good name for a postapocalyptic TV game show. But we should come up with a name for that use of a reflector dot. Treble dam dot? Damn treble dot? Tizz-B-Gon? Diffractor dot? I'm blockin' here. Suggestions?

Whoa! you must be saving up bigtime for one of the Neo Orthos, yes?

Great price! You bought it then (the ad says it is sold now) ?

The guys are correct, the YHD-2 is a steal at 30 USD. I think you'll be impressed. One of the things I used to compare to the TP was YHD-2 drivers transplanted into a Pro 30 headset. Great little drivers, and you'll get a kick out of the YHD-2 stock headset too.

Truthfully I don't have to save to get a Neo Ortho.I want one but not sure if I want to spend big $ on it, so I am waiting for impressions. I am a late adapter so to say. Between O2 and Ergo AMT I am very happy with headphones now.

This is more consolidation and turning all the phones, that I am not listening to as much as someone will, into a new (used) CDP. I really need to upgrade my transport.

I seem to be in headphone rotation mode... On the ortho front, if anyone would like my Technics EAH-810 PM me, they have basic damping, but could certainly use some fine tuning, and the stock pads are now filled with memory foam, so they're in better shape than when I got them, but I'd be happy to let them go for what I got them for.

What are you using to fill in gaps on the baffles?


i use machine block sealer, it's like glue...
put it on the gaps, let em dry for 30-60minutes before assemble the baffle to cup again...
it seal very well, and if i dislike the result i can remove it right away like a sticker...
yes, it's like hotglue but not stiff, more like a rubber...

Now that looks like a good solid mod job. You make an excellent point about sealing the baffle to the cup. The rule of thumb is: for max low bass, go airtight all the way.


 
Even though, as ericj pointed out long ago, the replacement driver's part number is the same for all current Fostex RP 'phones, I believe the originally-supplied drivers are different. I think the stock T50RP does sound better than the stock T20RP mk II, even though pads, enclosure, etc appear to be the same. Glad to hear you've had good luck with the T20RP mk II. Like Faust2D says, seal every potential leakage pathway-- then you'll know how much low bass you can get from one of these miniaturized drivers.
 
Is that rock wool you're using to soak up random backwave mids and highs?
 


yep, not that i said that the driver are the same for T50RP or T20RP MK-II...infact they're different as you can see on the picture...
it's look like the different only on the plastic material...FYI this MK-II are the v1 (NOS from 2002 said the seller), so the pads are crimple and easily to flaking...
this belong to my friend, now he use my T20v2 modded until his MK-II are ready for the final touch, which is using a replacement pads...

T50RP driver were black I think these look brown in color. Are you getting any of these cool new orthos Wualta?  :)
 


it's more coloured broken white actually, not brown...

"machine block sealer"? is it RTV silicone based?
.


I think Ericj used some kind of silicone on my YH-1. Made a lot of difference and cleaned up some leakage nicely

I am trying to figure out how to improve my AMTs, but as I see it there is not much that can be done with them in Ergo housing. The drivers are amazing and housing gives them incredible soundstage, however bass impact, I think mostly due to backwave, is not that great. I am thinking of using something to really secure the driver to the baffle, might help a bit with resonance.

Given my experience with Heils, the fact that you're hearing any bass at all is a kind of miracle. Still, if there's any kind of air short-circuit that would let the backwave hit your ears without traveling around the sturzhelm first, toss in some silicone, silicon, silliputti, whatever it takes. As for resonance, wouldn't coupling the driver to the superstructure increase, rather than decrease, the danger of resonances? Guess it depends on how well-damped that superstructure is.

I was surprised they had bass, as I was expecting very little of it, yet it's there and it extend all the way, just has no slam like stats. YH-100 kicks like a mule in comparison, yet something like TK-33, SR-X or SR-Gamma has a lot less.
 
Neo ortho will have a lot of appeal to me if they can match stats in special and detail resolution yet have orthos kickass bass

I need some direct comparisons to stuff like O2, SR-404 etc.

I am thinking I need one or two prime examples of each headphone technology to keep me happy here, LOL.

Am being honest here,  I love the TPs and hate to have to admit this (especially since i don't think i can afford the usurper), the LCD-2 is more than a match for the TPs in the low frequency response. It does extend lower, the texturing is even more vivid.  For me most importantly, the LCD-2 sounds so much more 'real'.

When compared to YH-1000 or YH-100 is bass as deep and punchy? What about comparisons to O2? LCD2, based on initial impressions, seems to be one of the most interesting new phones around.

yup, Wualta...it's silicon base, actually it should be use with a spatula or similar thing to applied on the area...
but instead of using that (my mom not gonna let me use her) i use my finger...i know it makes a bad look, atleast it's work... LOL
the low & high impact are superb, as great as HP1k or SR404 LE or any other lambda...

Ah, this must be the black stuff I saw in all the little cavities of the T20RP mk II cup, baffle side. I think I should take a close look at that headphone to see if there are any bass leaks or little empty spaces for sound to get lost in. 
 
And it appears you didn't add any further damping to the driver, just filled the empty space in the cup with rock wool, right?
