Given how good I think the A7IV is, this is something I'll likely look for used in a few years. I really believe the sensor size is pretty idea. The A7RV I get to use at work now is pretty amazing but the file sizes are enormous and I often don't need that much resolution even for large (30"x40") prints.

Cool! Sorry if I added to the mess.

Oh, I misunderstood.... So I need an actual human head. Is this how Frankenstein starts???? I have a polar bear named Baloo in Minecraft, if I get another one I should name it Grawk.

Love it. How are you doing sir, still teaching? Any chance you'd take a glance at my McAllister mess/amp? I'd love to give it a refit.

has to be one of the ones that can be set to 12v like this Amazon.com: FARSENSE USB C to DC Adapter,Barrel PD Trigger Cable(3.3ft) with 10 Connector Tips,USB to DC Power Cable can Switch Voltage by Pressing The Key,Support LED Display Voltage : Electronics

Ok, interesting. So a Styrofoam head would be ideal and some sort of small size and highly sensitive microphone? Would the omnidirectional test microphone work, or are those crap. What about my roland device with some damping?

No. Not unless your head has the acoustics of styrofoam, the dummyhead needs to mimic the acoustics of a human head, mostly because of the proximity of your head to the microphones (earholes). The sound at the microphones is a very complex signal that is not just a function of the sound coming from the sound sources (unadorned live music -- throats and musical instruments; recordings -- speakers), but the HRTF that the acoustics of your head do to the sound as well. Paging @Dreadhead...

Who is making these???

Wait wut? Itll be so fun! *This is your left ear* They recommended the SM7B over on the other place over BEACN. Did I just stream of consciousness too hard. You ok Grawk? Need a mint?

Price? Sorry, I know I can google. They kinda look like omegas. How do they rate birgir?

This post just made me break out in hives

From an engineering perspective, hfm and stax differ in design in many aspects, the mesh stator alone cannot be used as a simple evaluation criterion. I would like to briefly discuss the following points: 1. Different Assembly Structures. Hfm uses glue to bond both spacers and stators, unlike stax driver house. Their assembly method also borrows from early Sennheiser and Sony design concepts, attempting to isolate the shell and driver vibrations through flexible coupling. In other words, if you disassemble any non-latest hfm headphone, you can see the driver is sandwiched between the EVA foam and panel on both sides. These three headphone assembly methods—"stax（driver house + rigid shell）," "senheiser、hfm（flexible coupling assembly）," and "completely ignoring vibration transmission"— will produce some differences in subjective listening, but these differences are not significant in the frequency response curve. 2. Different stator acoustic designs. Stax stator acoustic surface size is consistently significantly smaller than the diaphragm size. This design improves sensitivity a bit and also provides a gradient radial damping for the diaphragm. Limiting the acoustic surface size at the stator level is also one of the reasons why stax have a bit different image compared to other estats. 3. Different mesh counts. Stax uses lower mesh counts, such as 60-80 mesh in the Omega and x9000, while hfm uses higher mesh counts, around 300 mesh in the Shang JR/SR. Lower mesh counts result in more transparent sound waves, while higher mesh counts provide more uniform but higher damping, leading to audible differences in subjective listening, but there are no winners in this regard. 4. Different earpad and wearing design. This goes without saying, it greatly affects the sound of electrostatic headphones, and hfm and stax have almost opposite design philosophies. 5. Different diaphragm. Whether it's the thin film material itself(pet vs pps), the conductive coating, or tension, hfm and stax are all different.

A SRM212 with one of those USB to barrell jack adapters and run it off a normal USB power bank. 4W should be just fine of a 2A output.

at the moment, do what i did 30 years ago. srm212 plus 12v 7ah gel cell. its portable. kinda portable. or buy 4 x apex opamps and run them class C with the dc to dc converters. i wish i had a better solution. getting all those transistors to touch the heatsink at the same time is not easy. even the koss box requires a decent size battery. (6 x D cell)

Well, let's be honest, it was never portable. It consumes 600ma + more like 800+ for DC converters. No small battery can handle that—for example, 10 hours. Yes,we can use a power bank, but that won't be very portable.

Just checking out the local river as a result of the atmospheric River. not a good video and YouTube forced it to be a short which I hate. 🙃

no, omega-els has the hvrv-hansen portable. and the power supply blew up. so he is using outboard dc/dc converters to power the no longer really portable thing.

Just built as per schematic, and worked straight at first attempt?

Mine works without any problems. I tested it for 12 hours straight. Yes, it's quite hot. But all the heat is dissipated by the case. Power supply: +-400V. 5mA current consumption. 12V input. 1-2A power supply required. I'd say the sound is on par with KGSS, definitely not worse.

As it says in the title, think it could be a fun way to share vinyl while streaming. Thoughts? Any info on them? Something like they use for the STAX recording. Can I just use a bust and get microphones? Is it that simple? I have a Behringer DEQ2496 with a room analysing microphone for what its worth. I also need a more localized (just my voice) streaming microphone, Anyone have experience with BEACN? Or best to stick with Shure?

In the fridge? Years. In the freezer? Decades.

Driver size has nothing to do with performance over a certain threshold (say 60mm), I'd even say it makes a lot of parameters much worse. It's more down to the structure design, stator design and diaphragm properties. Stax are failing at all of these BTW... it's all bad. It seems there is very little interest in the 009D, goes to show with the stupid promotion they have running with them. Buy a set in December, mail them a registration paper (as in by post) and they will send you a 1.5m cable. They say it is the silver plated one so why include that and not the OFC as is stock with the phones. Makes no sense.

The main problem with the 009 is the driver size. They're simply smaller than the ES Lab or x9000. And the detail isn't as good as the x9000. If the 009D is the same as the 009, only for 2k+, then what's the point of buying it now? It's better to wait.

Need to find my old AE-1, might still have some film in the fridge. How long does it keep?
