Dice Electronics iTPA-220 iPod Tube Amplifier System

Add as a preferred source on Google


Dice Electronics’ iTPA-220 iPod tube amplifier system is a bit like a strict vegan meal served inside a hollowed-out animal’s skull. Sure, there’s no meat in it, but good luck getting vegans to dig in. On the other hand, if you’re just an omnivore looking for good eats, you might find a lot to like.

In this case, the vegans are audio purists who treasure the sound of tube amps, and the animal skull in the mix is an iPod, packing compressed tunes that said purists would cringe at the thought of. The iTPA-220 makes overtures to the audiophile crowd with its old-school tube amp, but also ignores their analog mindset with a piece of cold digital gadgetry at its core. It’s an enigma, to say the least.

To better understand, a history lesson: Widespread use of fragile vacuum tubes to amplify signals went out with the introduction of transistors in the 1950s, but they survived the latter half of the 20th Century and still exist today thanks to the audiophile community. They cling to the classic technology for the warmth of the sound it produces – an ethereal quality that has been much harped upon but never quite nailed down to any measurable trait.

The same purists that seek out tube amps usually avoid digital audio. They treasure vinyl for the same warm qualities they find in tube amps, tolerate CDs out of necessity, and cringe at the thought of stripping some resolution from music through compression, no matter how discretely.

The iTPA-220 ignores the clash of mindsets and throws old and new technology together into one chic-looking package. While Dice probably won’t get too many purists to sell off their McIntosh tube amps for one, the system has plenty of its own merits.

Dual 6N3 vacuum tubes sit like jewels in their settings on either side of the amplifier, with a dock for an iPod between them. Together, they provide 20 watts of amplification for two channels, and feed the signal out to included stereo speakers. The whole system is finished in an elegant black, and a single knob on the face controls volume. There’s even an auxiliary audio-in connector in case you want to forego the iPod dock and use another MP3 player or other source of audio.

The twin bookshelf speakers that come with the system use 1-inch dome tweeters and 4-inch bass drivers. Dice claims the speakers’ “wood acoustic structure” endows them with a full dynamic range. They also tout an impedance of 4 Ohms, meaning they use they translate the amp’s output into sound pretty efficiently. Frequency response is between 40 Hz and 18 kHz.

Dice Electronics accepts preorders for the system on their Web site for $299. If you’re willing to set aside the fundamental collision of audio values at play, the iTPA-220 is one classy-looking audio setup that’s sure to draw spark some conversations when you use it crank out tunes at a party – and perhaps some arguments as well.

AI security cameras may soon recognize your walk before they recognize your face
A new AI gait system tracks body motion through skeletal keypoints, aiming at long-range identity checks where face scans and fingerprints fall short.

Security cameras are built to look for faces. New research suggests they may soon have another target, the small habits buried in the way someone walks.

A paper published in the International Journal of Reasoning-based Intelligent Systems describes SKDMap-Net as a gait recognition system designed to identify people from walking video, even when the camera doesn’t get a clean look at their face. Instead of relying on a close-up scan, it studies how a body moves from frame to frame.

A 20-second 3D printer breakthrough comes with exactly the kind of catch science loves
The process can create complex microstructures far faster than some laser-based methods, but full 3D control is still a work in progress.
Aluminium, Smoke Pipe

A 3D printer that can make a structure in about 20 seconds sounds like a lab claim wearing a cape. The clever bit is real. The catch arrives before anyone starts dreaming about instant replacement parts.

University of Utah researchers have demonstrated a holographic 3D printing technique that hardens tiny structures in one exposure instead of building them layer by layer. That one-shot approach could avoid the weak, leaky seams that stacked printing can leave behind. For now, though, this is a tool for microstructures, not a shortcut to printing whatever object pops into your head.

Amazon is full of copycats and shady brands. This Chrome extension lets you avoid them.

Shopping on Amazon used to be simple. You searched for a product, compared a few familiar brands, and checked out. These days, it often feels like you're scrolling through an endless parade of names that look like someone leaned on a keyboard before hitting publish. That's exactly the problem Knockoff is trying to solve.

Created by developer Josh Pigford, the Chrome extension doesn't promise to expose counterfeit products or magically tell you what's good. Instead, it tackles something arguably more annoying: the flood of unfamiliar, mass-produced brands that dominate Amazon search results.
