Now it shouldn't come as a massive shock to anybody but I'm not much of a SR-009 fan. From day 1 they always sounded messed up to me and the BK and S didn't really make it any better, even a bit worse with the 009S. To this day I have only one 009BK (as it is a limited edition) in my collection and one regular 009 that showed up here randomly and was a stark improvement over all the other sets I've owned. No idea why those sound different but better not mess with them. Now the plan was always to do something with the 009's to improve them but there was always something better to do. Well with surgery pending a couple of months ago, I finally had time to do something not too taxing. First off I needed a donor set and here is where that came in: I got these three years ago and they just sat there in a box. Too many parts missing with no spares available, three out of the four dust covers were trashed and I took off the arc to rescue another 009... so a pile of parts with fucked up drivers. The plan forward was clear though, the drivers needed new dust covers, new diaphragms, a way to mount the cable and finally some way to attach the earpads which wasn't 009 levels of stupid. Now none of those parts could be reused or they simply weren't there so time to do some designing. I still suck at 3D design but practice makes perfect... or it should in theory. Now first off, dust covers and diaphragm holders. These are easy to do as PCB's but materials, thickness, films used etc. are all large variables. Here are my first drivers, actually using the third batch of diaphragms as I slightly tweaked the dimensions once I started test fitting: Those familiar with the stock drivers might spot the bias connection is very different. I had to spend a lot of time cleaning the stock drivers, as they had been open for who knows how long, but this first test was successful. Fully balanced drivers and no noises from them at all so they are as clean as I can get them. The dust covers are 2um mylar-C, just lightly stretched (hence the slight lines visible) and the main diaphragms are also fairly loosely stretched 2um mylar-C, then heat treated and given a coat of fabric softener. The drivers are easy to align but one major part of this project is to find all the correct o-rings used to assemble these and in the right grade. When I had waited a month for a large shipment just for the one size I needed to not show, I even bought some stupid expensive examples locally. That got me here: All new screws used to get the drivers into the housings. You can see how beat up the aluminum housings are but hey, fine for a project like this. Now there was the next difficult bit, the cable entry: On the stock set it is a plastic guide which sits in those holes, the cable fits in that and the whole assemble is screwed down. Now the stock cable I had was not perfect so instead of making my own version of that... I just used a standard Lambda cable. A L500 was going to die for this set anyway (as I needed the arc) so why not use that cable. Here is my solution for that: This is 3D resin printed and is the second revision. First was just to check for hole size, alignment and if it was fouling on anything but it was way too shallow. This version still had to be sanded a tiny bit but it fits nicely. I did make a 3rd and 4th version which is incoming to clean up the design a bit and give me some more internal room. The earpads above are simply stuck on with some blutack so more on that... For the earpad mounting, there two problems there really. None of mounting hardware was included and anybody who had changed the 009 pads knows just how fucking stupid that mounting setup is. I also wanted to use non Stax earpads (not paying 300$+ for pleather crap) so here is what I came up with: Same idea really but I added a spacer between the plate and the driver housing so there is room to slide the lip of the earpads underneath it. The two layers of the PCB sandwich are visible there (along with the production number as I forgot to have it removed) and it works nicely. I could have made this from aluminum but it wouldn't have cost roughly 4$ then... This is the fitment with some random test earpads and standard 1.6mm PCB's. Works just fine and I can't find any issues with baffle seal... quite the contrary really. So here we are, the MA-009 This set of earpads has already been replaced and it takes a matter of seconds to swap them over. What a novel feature... Now what was the true goal for all of this, well besides having some fun doing something new... make a set of 009's I would actually want to sit down and listen to. Now this project is far from over but here is something novel... a SR-009 that has some actual bass output. They are still forward sounding but it has been diminished by a large extent. I can use these for hours quite happily, even at my usually higher volume levels. The decision to use 2um mylar was to try and tame that forward edge and it has been partially successful. A stock set of 009's is terrible on most music I try them with, this one is mostly good with just some tracks which show how bad that stator design really is. There is this slight forward sheen over everything and it simply has to be the stators as the rest of the headphones has so much in common with the 007 overall design. Now the major issue is driver stability as the left diaphragm really likes to get stuck to the stators and I have to open up the driver to get is back on song. I might have gone too far in sealing them up but I wanted some bass dammit!! I will make some more test diaphragms and see if I can make some which can handle the pressure of going on the head energized while giving the sound I want. For now I'll just use this pile of parts to make some music... So to end off... if anybody has a set of 009's with blown drivers that are collecting dust... hit me up and I might want to buy them.

For those of you so inclined.....my nephew (niece's husband) Chris is in Russia (Kazakhstan) now, and he will be launching EARLY local time on a Soyuz rocket to go to the ISS!!! Streaming is available at https://plus.nasa.gov/ 3 highlights (times are EST):

Had dinner with @cetoole and @MexicanDragon, who graciously drove out to meet me in Lake Forest Park. I am also convinced Seattle is entirely too cold for me. Get me back to sunny California!

Starting to look the part!

Bourbon pecan pie.

Congrats to Chris! Perfect launch.* *to time with my middle of the night switch from legs to breasts in the sous vide.

Fuck it. I made a full batch. Cheers Matt!

I just got a colnago c50 with super record 11, but no pictures until Christmas because it’s under the proverbial tree.

Got a ride with the ANG two weeks ago to check out our remote project site in what southerners call Northern Maine (Bangor area). They had an issue with the first aircraft, but thankfully had a spare, and the delayed departure made for a convenient return time.

Indeed!! My mom said his kids took it hard when he left for the rocket but were excited to see him in the ISS itself.

Thanks all! Wasn't the celebratory day Karen would have recommended.... Fighting a cold, and did some work starting at 4:30am! But after all that, was able to chill for much of the day. Realized I hadn't done that for a long, long time - a few hours here or there but not for basically a whole day - and it felt damn good! Needed to recoup some but also just shut things off. And having Andrew's cat June purr in my lap was good medicine, too. Andrew ended up bringing in Thai for us for dinner; our planned excursion out will be a rain check.

Arrived

My plate was almost as decadent

Saw Mary Fahl last night, I think the 6th time I've seen her (7th if you count October Project in 1995). Wonderful concert, some of her hits, October Project hits, and covers. The whole second set was her adaptation of Pink Floyd's Dark Side Of The Moon, pretty stunning. I think this may have been my favorite show of hers. Got to chat with her and her husband after the show, and also met 3 folks with whom I'll keep in contact ongoing; just some amazingly nice people.

Al and I just prepared Eggs Benedict for the Mayberry compound. I may have overdone it. See you all after a brief food coma.

I won an album today. Sharon Mansur's Trigger -- which is jazz fusion and unholy carp, this might break me -- it's right up there with Hiromi and Fox Capture Plan! Just listen to this shit:

Meanwhile, in San Rafael , it's beginning to look a lot like Christmas.

Glad that you got to see Colin.

Jumpstarted the holiday cheer (winterless necessity) with a trip to lights.

Thanks Ric! Something was meant to be, we had a power blip at ~3:45am EST and my alarm keypad beeping woke me up. Managed to watch the launch as well! Time for caffeine....a whole fucking bunch of it! 🤣 Have a 3.5-4 hour (if I'm lucky) drive in a bit.....

Bit excessive but I got an unworn Platona from EWC. Traded the Lange 1815 Chrono and a couple of other watches I wasn't wearing much. We're all going to die soon, might as well enjoy it. IDK?

Had not made empanadas in a while. Decided that needed fixing so I defrosted some left over carnitas and that was that. Well, first I made a double batch of dough so I could make them more hand-pie sized. This was half of them.

New Tricky album I got for my bday... feels like I'm in Highschool

Cheers Matt!

Have missed a few of our normal holiday events this year, so happy to see Mountain View went all out for last night’s tree lighting ceremony.

It's the start of the Holiday Concert Season at the College of Marin

Met @swt61 in the Costco parking lot. By Chance.

Decided to have a go at Chicken Korma. Bites while seasoning were pretty great. Naan is staying warm in the oven to go alongside.

Finally the PCB's arrived for the Kiwi Ears headphone drivers: Just three different PCB's needed, on the left is the diaphragm ring which is a 0.6mm pcb but with no solder mask so it is actually 0.51mm. This has to be ENIG to make it completely flat but most fabs require that anyway. Film is 2um mylar-c as that is so simple to get and relatively easy to work with. In the middle is the dust cover holder/spacer. I made this 1.6mm thick as that way it clears the stock lip on the baffle that was around the dynamic driver. I used the first one as spacer and then stacked up the driver sandwich. For the dust covers I used the same mylar as the diaphragms but not stretched as much Finally the stators, 1mm ENIG pcb's and this is the outer side with the inner side having a smaller active area, aka like the SR-007. Holes are a bit less than 1mm but that can easily be altered for another run. Here they are assembled with the only alterations to the baffle where I counter sunk the mounting screws. There were just the three holes there in a row and with the earpad mounting plate being flush to this, it had to be done. One second with a counter sunk bit will do this as this is nasty, cheap ABS plastic. Here they are assembled. Only mods to the chassis is that I enlarged the two holes there are on each side (cable entry and a port on top) to 5mm so the strain relief would fit and the solid plastic plug I glued into where the port is. The cable is the 6 core silicone wire that can be found everywhere now with a 3D printed Y-split and Stax plug made from an XLR plug and pins. Now for the sound... lets just call it work in progress. This is very much the first draft and one channel is slightly weaker than the other (I swapped out the diaphragm for another which fixed it mostly) so I need to look into that. I'll probably just build a second pair of drivers so I can match them into pairs as I have another set of the headphones. Massive baffle leak too and the housing... has issues... so bass is not their strong suit for now. That needs to be fixed but I might have to get creative with that. Still for a cheap project that took only a few hours to make and cost less than 150$ all in... there are worse ways to spend an afternoon.

When I was a kid my Mom made the same Thanksgiving dishes every year. One of them was green bean casserole. Probably like many of your Moms made too. I didn't hate it, but I didn't love it either. Canned green beans, French's fried onions and cream of mushroom soup. Like many vegetables and other dishes of my childhood I didn't know that I liked them until I was living on my own and tasted the fresh version. So I thought the concept (Trump joke) of green bean casserole was good. But what if it was elevated to using fresh ingredients? So today I set out to test that theory. I trimmed and sautéed about 3 pounds of green beans. Then sliced and sautéed a large amount of mushrooms in butter and white wine. I decided that making my own fried onions might not be worth the extra effort, so French's fried onions it was. In place of cream of mushroom soup, I used cream of celery soup, as I like the flavor better and had already incorporated fresh mushrooms into the dish. I have enough for a small army, as I had planned to take this to Al's before catching a cold. How is it? Well it has about 15 more minutes to bake, so I'll let you know later. You can't tell, but there are two layers of everything in the dish.

Hope you feel better soon.

A slightly different kind of speaker porn. In the early 90s I was prone to spacing out and doodling in class, in stead of doing what I was supposed to be doing. This pattern explains a lot about ...everything that has followed since. A month or so ago I was going through some of the myriad of paperwork that made it with me from the mainland. In it I found a really old school notebook. Most of it was fantastically uninteresting (I have not cared about the Sumerians for 35 years and counting) but I did find one page that had some amusing doodles on it: We've got a couple cars, an attempt at a Roland TB-303 Bassline, what might be a Marshall half stack and ...two attempts at one very iconic speaker design. That's a Legacy Audio Whisper. I was one of the cool kids, I tell you.

Some 18s:)...Don't know how Juan's celebratin'...

I'm afraid it'll start talking to me if I open it up... But perhaps there's a science project in my future to see what happens when I do.

Few more from the drive....the first is my new Spirit Animal!

Meanwhile...

I had no idea they were the first ever Conan musical guest. Talk about starting on a high note!

A while back, I bought a lot of camera gear because I wanted one specific piece. The lot was cheaper than the item on its own, because eBay. Included in the pile of gear was a Tamron "vacation lens" (all-in-wonder, not good at anything) 28-300mm F/3.5-6.3 Di VC PZD A010. Yes, that's its name. I was not expecting much with the Tamron and it's barely delivered even on that meager promise. With that said, I did have some fun with it. This past September, I took the 5D IV and Tamron for a walk around downtown EDG. This New Beetle is parked in front of this shop all summer. 78mm @ F/9, 1/200. Old Beetle! It made genuine air cooled noises, and belched out noxious exhaust fumes. 87mm @ F/8, 1/200. The main drag, which is one way, because it was built for horses. 70mm @ F/8, 1/200. Zoomed in on the same, 179mm @ F/7.1, 1/250. Main St. never meant to hold a Wagoneer. A rather famous boat, with Chappy in the background. 28mm @ F/10, 1/320. Speaking of famous, the Dolphin returns to harbor. 71mm @ F/10 1/320. Both On Time ferries, 109mm @ F/9, 1/320. A Series III on Kelly St. That's a pet pickup truck I see in the summer behind it. 195mm @ F/7.1, 1/200. The line for the On Time, Daggett St. 97mm @ F/8, 1/160. Mose St. is two way, and has parking. It's even less suited for Wagoneers. 97mm @ F/8, 1/200. The Connaught House, now just another goddamn rental. 109mm @ F/8, 1/250. North Water St. 179mm @ F/7.1, 1/250. A cute MG and absolutely garbage bokeh. 223mm @ F/7.1, 1/320. South Water St, which I have callously ignored for 20 years now. 87mm @ F/8, 1/200. September is still vacation for some. 43,mm @ F/8, 1/250. The Tamron is not a very good lens. It covers a large focal range and not well. I had to work over many of the above pretty thoroughly to get decent results. I also had a bunch of shots that were not really worth the effort to salvage. Tune in next time for Vineyard wildlife and some seasonal colors.

I saw the launch as well. Looked like a hell of a ride to be strapped to that thing. Glad he made it safe!

But hopefully not too far in the evening. https://theonion.com/astronaut-hates-long-nightly-spacewalk-to-iss-outhouse/

I, ahem, like to sing sea shanties, so I cheerfully pay for Proton VPN. Don't let the UK government back you into a corner!

That's awesome! Congrats to him on being the furthest from Trump one can get.

Zero Mattnog posts since 2023. What a sad state of affairs. I was just reminded that I failed to make a batch again and I am disappoint in myself. Anybody else make some or still have some in the back of the fridge? Is a month enough time for it to gel?

I'm not ready for a new espresso machine as the Lelit Bianca I bought some years ago is still doing a great job, but I found an announcement from Fellow interesting. I bought a Fellow Aiden I have been enjoying thanks to @luvdunhill , and have been receiving Fellow marketing emails. Here is an early review for the curious. I have to admit it piqued my interest, particularly how quickly it heats up. Looks like it can be bought for $1200 with an early discount and they toss in a credit for coffee beans. https://www.engadget.com/home/kitchen-tech/the-espresso-series-1-is-the-new-crown-jewel-in-fellows-coffee-gadget-lineup-170008473.html HS
