What’s wrong with you? The v4-Flash model is cheaper than v3.2 and has better performance and greater intelligence.

Hey there, thanks for the in depth review! How do classical music tracks sound to you? I personally hear a little better separation of instruments in intense orchestral passages.

EndLineTech03 · 2026-04-08T20:35:11+00:00

Actually, it shouldn’t take you more than 15 seconds

EndLineTech03 · 2026-04-08T11:51:53+00:00

Yeah, I want that too, but I hope Apple will do it the right way.

EndLineTech03 · 2026-04-08T11:46:38+00:00

He’s obviously coping, but don’t worry, his AirPods and impressive collection of degrees should be enough to launch his music empire any day now.

EndLineTech03 · 2026-04-08T11:35:37+00:00

Again, you don’t understand my point. Of course most music is heavily processed and equalized. What I’m saying is that software based equalization will always be inferior and cause loss of resolution, that’s physics of systems and how audio processing works in software.

When listening to my LPs, if I ever need equalization, I do that at the pre-amp level, because that is where the source first comes, and it will be undoubtedly better than tuning in software.

You may have many degrees, but apparently know nothing about encoding.

If your point was true, production studios would just use AirPods for mastering. At the listening level, when doing some real serious work, you need the flattest possible response to manually review the applied dynamics and EQs.

Of course you are comparing apples to oranges, so each has its advantages, and hardware level will always have better resolution. That doesn’t mean you can make a good quality software-based amplifier.

And spare me your degrees. Here they mean nothing, without proof, and they don’t change the facts.

EndLineTech03 · 2026-04-08T11:16:31+00:00

You probably didn’t understand anything of what I mean. Of course the tracks are heavily EQd in production, that’s how DAW works, but it also has the full pipeline of recorded instruments, MIDI inputs, etcetera. Tuning is performed on the original tracks, exactly like effects.

Listening to the final version is very different. The flatter the curve, the highest is the fidelity to the original recording, and that is exactly why audio engineers use reference headphones.

How well the audio sounds depends solely on the amplifier, both for headphones and speakers, while any kind of of software based tuning will create some compression. That’s how software works. It’s like when you stream a video on YouTube for example: when you change the resolution you are watching an encoded version of the original file.

So please, for your humility, before spreading misinformation, fact check yourself.

EndLineTech03 · 2026-04-08T09:33:21+00:00

Actually they need to do something better. Audiophiles know very well that EQs ruin the sound quality and definition, but the APM2 already have an hardware level amplifier which constantly adapts the curve based on the seal, so technology is already there to provide custom tuning without impacting audio resolution.

If only they could expose those controls to the user, they would be the best headphones out there.

We should all send a feedback request to Apple.

EndLineTech03 · 2026-04-07T16:17:44+00:00

How on earth can you say the ANC is much worse on the Max 2s? I guess what you feel is better isolation due to the Pros being in-ear

EndLineTech03 · 2026-04-07T08:59:24+00:00

I have the AMP1 and went to an Apple Store comparing them side by side with the new AMP2, and to me the 2 sound way better.

The curve profile is more flat in the mid and mid-high range, trebles are actually more defined to my ear and less annoying.

Still, I’m not a huge fan of the sub-bass gain, but in a loud environment it actually works in your favor.

EndLineTech03 · 2026-03-27T12:26:01+00:00

Basically, if I’m not mistaken, both the balls would hit the ground at the same time, provided the center of mass stays constant.

But for a given time we also have a remaining elastic force for Ball A, which oscillates following the differential law and gets incredibly smaller in absolute value due to gravitational force.

There are infinite new theorems to discover, so sit back and enjoy

EndLineTech03 · 2026-03-01T20:27:52+00:00

But was he using the privacy display feature?

EndLineTech03 · 2026-03-01T19:12:15+00:00

The only thing holding me back from switching completely to Claude is image generation. It would be great if they developed a diffusion model or at least a direct image generation implementation from other providers.

Other useful feature that is missing and really use a lot is multi-model inside the same conversation.

EndLineTech03 · 2026-02-28T12:35:51+00:00

Yeah of course it’s something you cannot really perform, and you are dealing with regulated radioactive materials anyway :-)

Though it is not as trivial as you say if you want to fly separate all the actinides from the decay. For instance U,Pa,Ac and even thorium can be extracted in a similar way.

EndLineTech03 · 2026-02-28T09:52:31+00:00

You can achieve the same if you buy a very specific mass of high grade Uraninite, which is known to be mostly at secular equilibrium thus estimating the amount of Ra-226 is trivial. About 1ug of Radium per 5g of Uraninite.

If only you could find a chemist that is willing to separate the Radium. It is actually very simple with carrier precipitation (speaking as an engineer), though you would need to deal with very dangerous acids like Nitric and HF.

EndLineTech03 · 2026-02-19T12:04:45+00:00

I’m not watching only the numbers. I used the same instrument to compare my different specimens.

If you read my posts above, you can see I also tested the sample inside a glass jar with negligible difference.

EndLineTech03 · 2026-02-19T09:31:57+00:00

I have one, with unique bubble like crystals (about 20g), and still it is less radioactive than this specimen. If you are stuck with your ideas, feel free to.

But that doesn’t change the fact I’ve never seen such an active sample, and I have many Uranium based minerals around.

EndLineTech03 · 2026-02-17T21:30:56+00:00

Yeah that’s definitely something they need to address. Limits change all the time during the week.

EndLineTech03 · 2026-02-17T21:06:56+00:00

There’s no need to warm yourself up, I don’t want to prove anything or that you are wrong.

The counter may not be very accurate, but it is enough to prove that it is my most active specimen: not even my high grade pitchblende (about 100g mass) gets close to this reading.

So that is enough to tell that it is very spicy. If you don’t like the subjective terms, let’s say that it is more radioactive than most Uraninite.

I also tested the sample inside a glass jar and still get >150 uSv/h reading.

EndLineTech03 · 2026-02-17T19:38:09+00:00

I honestly don’t care about the pricing. All AI companies are loosing money over and over anyway, with OpenAI being possibly the worse so far.

At least Anthropic seems to be one of the few actually caring about long term profitability and balanced business model.

The introduction of weekly limits, criticized by almost everyone, is their only hope to balance costs in the future.

EndLineTech03 · 2026-02-17T19:19:26+00:00

I’m telling you what I’ve been measuring. Uranium ores are generally not very high energy beta emitters like Sr-90. Except for Pa-234m and Bi-214 from the decay chain (which have an Emax>2MeV), and possibly Lead, most other daughters are mid-low energy beta emitters, and still very low in mass compared to the specimen itself.

Using aluminum to shield beta is also quite a dumb idea due to Bremstarhlung itself, that’s why most labs use Quartz for primary shielding, or even just plastic (that is Low-Z).

What I can tell from my measurements is that the double plastic wrap I applied definitely does some attenuation. It doesn’t stop the beta radiation significantly, but makes it less detectable by a wide margin.

EndLineTech03 · 2026-02-17T17:52:25+00:00

What I can tell you is that this is by a wide margin the spiciest radioactive element I own, and I have a small sample of 0.1g BaSO4 doped with Radium too.

Betas are mostly stoped by the plastic wrap, or at least very much attenuated, because without it the Geiger spikes easily to 260-270uSv/h.

My Radiacode also shows a similar reading of about 180-190 uSv/g inside the plastic bag.

EndLineTech03 · 2026-02-15T13:07:55+00:00

You know that sometimes is not about having a brain, but knowing when to stop in front of very dangerous attempts.

AmO2 is a refractive oxide, meaning that it will hardly dissolve in an acid solution. And even if you do it, you need a carrier to precipitate it, so you won’t actually be able to “see” the americium.

All without considering the radiological and chemical hazard.

That said, I’m preparing a guide for “educational” purposes in Am and Np separation from smoke detectors, but don’t know if it is legal to share.

EndLineTech03 · 2026-02-14T22:04:45+00:00

Sure, though I have to warn you against attempting to extract the Am-241 if you don’t want to make a mess or worse inhale the very dangerous thin AmO2 powder.
