Closing the Pi’s sound quality gap on the big boys are third-party manufacturers like France’s ALLO Digital whose terrific DigiOne HAT add-on directly connects to the Pi’s 40-Pin socket to pull digital audio upwards to output via S/PDIF with reduced amounts of jitter and/or electrical noise. Once landing on the newly installed upper deck, ALLO’s audiophile-sensitive circuitry can better nurse an easily disturbed digital signal.
Here we get a choice of coaxial or BNC. Both top out at 24bit/192kHz, no DSD. A non-issue for Music-First Audiophiles like yours truly whose favourite music is rarely released at anything higher than CD’s 16bit/44.1kHz. The DigiOne served as a sharp reminder that better streaming hardware can juice more from our DACs than pumPing up bit- and sample-rates and that such hardware doesn’t have to sell for megabucks.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
