    Wait, you own an SR-1, are you the guy with the "MrTechAgent" youtube channel? I've quite enjoyed some of your videos on vintage cans if that is the case.

    This guy also uploaded a manifesto saying he was inspired by Anders Behring Breivik and his terror attack in 2011, planned for years apparently. Absolute piece of shit.

    The Headcase Stax thread

    So, I just received a Stax SR-X MK3 normal bias today which is in absolutely immaculate condition. It's at least 40 years old at this point but for all I know it could have been opened a week ago. It also sounds really, really good to my ears considering the very low price I paid for them, easily beating out anything I've heard at sub 600-700 dollars. I've seen that the pro bias version of these is apparently all the rage, how do they differ, sound wise?

    Interested depending on cost Edit: If there will be runs for GRHV and GRLV as well then I am definitely in for a set.

    I want to convert a 580v DC bias to a 230v DC bias for so I can use both modern and older stax phones off my amp. Would a simple voltage divider do the trick or would I need to be careful about something else? The plan is to just tap of the pro bias outputs L/R and then use a voltage divider to get correct bias.

    Out of curiosity, where is the dust cover of the 007 located? In the modern lambdas I can see it from the outside (the thin plastic outside of the stator, right?) but I don't see it on 007 even when zooming in on the pictures @spritzer took of port modding 007. Does it just not have dust covers?

    Basically yes, the front volume is the part of the driver enclosure that is sealed to your head.

    Porting the front volume of a headphone shifts the bass response upwards, more midbass less subbass. The extent to which it is affected depends on port size. As for what is being vented you have the front volume (facing your ear) and the back volume (facing outwards). For the sake of bass extension only the front volume needs to be closed, which is why open headphones can have good bass extension, in other words the back of the drivers are completely "open" as you state it but the front of the driver is sealed to your head with the pads. I can't answer your question about the 507 pads, but I'm sure someone else can chime in/have experience. Personally I would not vent the front volume, 507 pads seem like a much better bet.

    Part Sourcing Assistance/Advice Thread

    Looking for PCB terminals (soldered on and with screws for wire) for my KGSSHV. Pin spacing is 5mm. Can't find anything rated for high voltages, everything seems to be 150/250V.

    Looking at Danish trustpilot they seem to be legitimate. I believe I know people who have ordered from their Norwegian branch and got their products as advertised. If we assume their feedback on trustpilot is legitimate then the only thing a few people have been complaining about is somewhat slow delivery. Take it all with a grain of salt of course, I have no first hand experience with them, but they do have a physical store it seems. Edit: Veterans on a Norwegian Hifi-forum attest to the store's credibility, I'm inclined to believe it is real.

    Calling it a review is probably a stretch, advertisement is probably closer to the truth.

    Part Sourcing Assistance/Advice Thread

    Currently sourcing parts for a KGSSHV, using a BOM I got from spritzer (don't know who made it). Have been able to find most stuff, my main problem is the 130V zener (625-Z4KE130-E3 on mouser), the 3N254-E4/51 (currently EOL and minimum order of 120, which is more than I'll need in a lifetime probably), and the 1000pf/1000V cap. I found the 562R10TSD10 as a possible replacement for the cap, would that one be fine? For the 2 others I can't find anything that looks like a good replacement. Any help is appreciated.

    Today I found out that my watermelon head does not fit in the l300 headband, the headband is simply not wide enough. I know the l700 headband is generally larger but how much wider is it? I really like how the headphone sounds but good grief is the headband a pain.

    Thank you very much, both of you! Looks like I'll end up as the owner of some L300L's
