I recently picked up a used Nikon 300mm f/4 PF lens, as prices have fallen for F mounts ever since Z came along. I already owned the old Nikon 300/4 AF lens as well as a 300/2.8 AF (screw AF), which is hy. In any case, I have really enjoyed having the PF...compact and lightweight, the optics are...

I've been using Apple computers since 1985, an owner of more than a dozen different Macs since 1994, an Apple Developer since 2000, a user of every MacOS that ever existed (even trialed NextOS before Jobs went back to Apple), and I've dealt with tens of thousands of cases of Mac connectivity...

Tried this before, but it is not a core audio issue. Instead, there is a deeper issue with Mac and USB peripherals that transcends type of device. There is basically some kind of fundamental flaw in Mac OS when it comes to USB device detection/connection that they never bothered to fix. I have...

This is a far more complex issue than power requirements for speakers. Dalis have variable sensitivity, but usually moderate to moderately high. Of course you want to make sure that your speakers are adequately power, however, I couldn't imagine working such a complex system without some kind of...

I recently made some rather sturdy pieces of hardwood furniture, and I have been checking out their resonances. For example, this bar stool and foot stool (Japanese elm). Striking either them yields audible resonance in the neighborhood of 1 kHz, in the female side of the vocal spectrum. It is a...

This is a no-go in earthquake country, Earth resonance would topple such a tall and narrow footprint stand.

I tried swapping to many different cables, and the same issue occurs. Also, the same kind of problem occurs with other USB devices, so it likely isn't the D90 either. Rather, the problem is with Apple and flawed detection of connected peripheral devices in general (HDMI connections tend to be...

My MacBook Pro recognizes my D90 (MQA version with AK chip) about 60-70% of the time...other times, I need to power off (back switch), disconnect/reconnect USB connection to the computer, and then re-start the D90. This always works for me, although it is somewhat of a hassle.

Oh yes, a new speaker cone design, and they also have a "Rubikore" as well...pretty sexy looking: Looks like these are indeed available in Tokyo (Dali is quite popular here, maybe the Menuet helped).

Wow, I never see them so cheap here in Japan. They are usually 3X that price. If I did find such a deal I would buy them (I am looking to upgrade my system in a second room, Rubicons would be ideal). If you could find a similar markdown on Epicons, even better!

I've owned a pair of these for over a decade, now they're in a side room system attached to a simple network Marantz integrated amp and they punch way way way above their weight class. I've also listened to much pricier Dali speakers and they all have a great sound that couples with typical...

I saw this newsletter in my email and welcome the new functionality. But honestly I don't encounter a lot of clipping in my experience, but this will clearly be different depending on what we're listening to, what kind of sources are used, etc.. When I've heard such artifacts I usually chalk it...

My wife discovered a wonderful playlist on Tidal called "Turkish Funk" which has opened a treasure trove of legitimately captivating 1970s funk, psychadelic, etc.. It transports the listener to a hazy huka lounge in Istanbul in the 1970s, probably a lot of mind-altering substances floating...

Shoyu ramen I ate for lunch yesterday at a small hidden restaurant near my office I just discovered…

Yeah I suppose, especially since prices have been going up. But again we have to think about sampling bias here, and scale it accordingly. We hear mostly reports of lemons, but these are on the tail of a wider distribution. If the worst lemons a company produces quit after 4-5 years, then I...
