August 5, 201015 yr I don't see an easy way of replacing the pins. This is what audiocats did with Neutrik pin sockets: Tuitorial: How to make a "wood case friendly" stax socket with silver plated Neutrik contacts. - Head-Fi.org Community But I already have a pair of teflon sockets, so I'm good to go. And I actually don't particularly care that the WPI pins are tin plated brass.
August 5, 201015 yr Yeah, I saw that thread, I was asking because the walls of the pins for these: 10 CMC 4P Tube Socket Glod Pin Hex-Snap 2.7x13mm Hole - eBay (item 130342228210 end time Sep-01-10 05:19:43 PDT) seems to be a bit thicker than the ones used in his mod. I'm not particularly sure if they would fit. I'll find out when I get them I guess.

August 5, 201015 yr I'd say the pins are less of an issue compared to the WPI socket simply not being the correct size for the Stax plugs. That's why they are such a pain to use compared to the teflon sockets or the SATO Parts Stax sockets.
August 5, 201015 yr They have switched to WPI on everything now which makes no sense to me and yeah, that's the transformer box. I compared it briefly at CJ against my Lundahl box and even the the much lower ratio of the Lundahl's they were much smoother to my ears and the bass more controlled even off the WA5. I think the worst offense is the use of Normal jacks without plugs when the damn units are set up for Pro only bias stock. There is the potential of many damaged Normal bias Stax cans on that box. I almost plugged my precious Lambdas into it at CJ, but decided to ask, then get better clarification before I plugged in. Since they're being so cheap, how hard is it to stuff the end cap of a BIC pen into the center hole?
August 5, 201015 yr won't fit. You would have to drill the thing out. Given the kind of plastic its made from it will likely break.
August 5, 201015 yr Damn. The parts are on their way... I'll try to take a sanding bit and open it up a little instead. If it gets ugly... well... off to local hardware store for cheap xlr jacks.
August 7, 201015 yr Anyone here want my SR-5NBs? For a price, of course. I thought I'd let HC have first dibs before I make a post on the other site.
August 8, 201015 yr So between now and when I get a working stax amp, I've been researching more on the "etchiness" people talked about in the SR-404. If my understanding is correct, this is due to the natural resonance of the drivers being in the mid-high frequencies. To remedy this, stax used glue to "fix" the drivers to the baffle in the old lambda series, and this took away the vibrational energy at those frequencies. The SR-404 used glue that was not as good as the one they used before, and the drivers could not get the same amount of adhesion to the baffle; thus the etchiness returns. Is this correct? What's a good replacement glue for the default adhesive? (Good to know if the etch drives me crazy >.>) Also, when the driver is fixed to the baffle, doesn't the vibrational energy get carried over to the baffle as well? Does the SR-404 have thick enough of a baffle to damp it? In short, does it do tack or tock when you tap on it?

In short, does it do tack or tock when you tap on it? The baffle is a solid piece of metal (don't know what, is it steel?), which is held down to the plastic chassis by four screws, and the pads are glued on the other side. So basically the energy goes to the entire headphone. Edit: This is assuming 404 works same way as vintage Lambdas And I say meh to 404 etch. Edited August 8, 201015 yr by mypasswordis
August 8, 201015 yr Oh, so it's a slab of metal, not plastic? For some reason I had thought the SR-404 used a plastic baffle... And I say meh to 404 etch. We'll see how it goes.

I am immune to the etch.
August 8, 201015 yr Can't wait till I'm that old. It has nothing to do with age, iirc it's around the 2-3kHz range so no way a part of age-induced hearing loss of HF. And cool, I might just take you up on that offer, Dusty. Always curious.

Does the SR-404 have thick enough of a baffle to damp it? In short, does it do tack or tock when you tap on it? I did fix one set of drivers permanently to the baffle and while it did make a difference, it was quite small and certainly didn't fix the midrange peak of the SR-404. Going by my experience with the SR-007Mk2/A this shout has more to do with the distance from the drivers to the ears which is why my well worn set doesn't have any. Either that or it is an Airbow SR-SC1 with the label on the plug removed...

August 8, 201015 yr Stax SR-507 coming in September in case you haven't seen it. USD $1,200 (approx.) according to a post this morning on the other hps site.
August 8, 201015 yr I wish there were a way to make a sub-topic. Replying to the thread can get tiresome to search! My question is about the resistors that are INSIDE the phones. If there is a 5M ballast resistor already inside the amplifier, what is the purpose of the resistors that are inside the cans (no one says "cans" around here ))? At least the last time I replaced the cable on my SR-5's, I found a resistor inside each phone. Next time I have one open I'll measure it!
August 8, 201015 yr There have been rumors of a premium Lambda for some time now but I still don't see the point of it. Now if they had taken the 4070 and simply changed the cup design it would be killer but this... I'm not so sure... I wish there were a way to make a sub-topic.

These bridge the two stators and protect them for voltage over 450V so you can damage the diaphragm
August 8, 201015 yr It has nothing to do with age, iirc it's around the 2-3kHz range so no way a part of age-induced hearing loss of HF. I don't think it's hearing loss, I think it's psychological. So I guess the correct retort would have been, "can't wait until I'm that mentally challenged"...No, wait, forget I said that. I would also presume that if it was pronounced enough, I'd probably start being annoyed by it, so I am specifically saying that I am immune to the etch as implemented in Stax headphones. Grados, on the other hand...
