About The Product1. LINEPAUDIO A962 fancier-level HiFi Vacuum Tube Power Headphone Amplifier PreAmp, made of Beijing classic quality 6J9-J vacuum tube, USB-PC supported ASIO sound effect software will give out more professional, full, open-stage, soft and smooth sound, especially applicable to voice, string music, light music, and classical music, the performance of different frequency points is so perfect! Fine at high frequency, strong at low frequency! Easily drive 16??-600 ?? headphone of any class, quiet background without any current background noise! Two sets of audio signal inputs, one is USB signal input (USB-PC), USB cable is connected to PC, plug and play without a drive, directly used as an upscale USB external sound card. The USB port can be also connected to any model of Android mobile phones with OTG function. The other is 3.5mm interface audio signal input and you can connect it to mobile phone, CD, lossless music player or other audio source devices. In case of simultaneous inputs of USB signal and 3.5mm interface signal, 3.5mm interface signal input is preferred.

3. Many music fanciers are concerned about the background noise of vacuum tube headphone amplifier, but this product frees you from this concern, its performance in controlling background noise is extraordinary, the background is quiet after several tests and optimizations of the circuit design, without any current background noise, you will hear the purest, most natural, and most nostalgic sound. As to the testing of the current background noise: as it is known to all, the current background noise comes from two sources, one is the vacuum tube headphone amplifier, the other is the audio source or the audio cable (the audio cable makes it more likely to generate background noise), the correct procedure of testing the headphone amplifier is to disconnect the audio input cable, with power on, if the background of the headphone amplifier is quiet, it indicates that the headphone amplifier has a very high SNR. If unquiet, or this seriously affects you from listening music, it indicates that the headphone amplifier has a very low SNR.
4. Notes: An electronic interference device near the desktop may also affect the SNR. For example, if the vacuum tube power amplifier is placed near a wireless router or device, it may be interfered to some extent. Enclosed by an aluminum shell, miniaturized but exquisite, the front, rear panel is precisely processed by CNC machining center, you will get a terrific handle, the ultra-small volume will not occupy your desktop space too much. More than a multi-functional upscale high-fidelity USB sound card vacuum tube headphone amplifier, it is also a beautiful desktop ornament. All letters on the machine panels are printed using expensive laser carving and will never fade off.

From Pixels to Problems! Great read!
Format: Hardcover
“Play Nice” offers an enjoyable deep dive into the tumultuous history of Blizzard Entertainment, chronicling its journey from a ragtag group of brilliant college students to its evolution under corporate ownership and its current state. Schreier provides fascinating insights into the antics of Blizzard’s early employees, showcasing their outlandish attitudes, relentless work ethic, and tight-knit camaraderie.
The book explores how Blizzard transitioned from a company renowned for producing high-quality, polished games that left competitors in the dust to one struggling to preserve its heart and soul amid mounting corporate pressures. While the corporate side and C-suite executives are often cast in a negative light, Schreier thoughtfully examines the motivations behind their decisions, offering perspectives from all levels of the company—from executives and middle management to QA testers. This balanced approach provides a refreshing take, avoiding oversimplified blame and instead considering multiple sides of the story.
And while it’s easy to villainize the suits in the boardroom, Schreier does a great job showing why some decisions were made. From executives to QA testers, he pulls back the curtain to reveal a mess of perspectives, reminding us that every bad decision has some kind of reason behind it (even if it’s still a bad decision).
The book also revisits the scandals that put some serious smudges on Blizzard’s reputation, offering new angles and fresh commentary. As someone who once lived for Blizzard games—cheering at Overwatch League matches and losing entire weekends to Diablo marathons—I can’t help but root for Blizzard to find its way back to glory. And hey, if it means waiting another decade for their next masterpiece, so be it. It’s done when it’s done.

Great insight into an otherwise obscure world
Format: Hardcover
As someone who grew up playing blizzard's games for an unfathomable amount of hours I've always been interested into their inner workings, especially considering their downfall in recent years. This book holds a ton of information and knowledge, is well sourced, and is the work of someone with obvious deep familiarity with the industry and its particularities.
Besides the information itself, the book it written in fun and interesting prose, and it keeps the rhythm fast and entertaining, so it reads more like a novel than a journalistic article.
Overall, an entertaining piece of insight into a world that is normally quite unknown, even to long time gamers like myself.

Great insight on what happened at Blizzard but...
Format: Kindle
My main issue with the book is the lack of non-american stories that explained the bigger picture. As a former Blizzard dev, there's much more than what happened in Irvine and Korea, with Europe's office mentioned almost as a footnote, and nothing else from the other regional stories. Shame but I guess the book would've been double the size.
