NOOIR CP01 60% Mechanical Keyboard Kit

Design that Dares The NOOIR CP01 takes design to a whole new level, turning a functional tool into a visual masterpiece. With a 60% layout, it strips away unnecessary keys to focus on what matters most. But while style may as well be its middle name, it doesn’t skimp on usability. The multimedia knob gives you control over your media. The two programmable spacebars and centrally-located Fn key deepen functionality. And, speaking of programmability, the keyboard is fully customizable with VIA. Centralized Fn key: all within thumb's reach The CP01 features a split spacebar design with the Fn key placed right in the center. This setup is great for those who want quick, one-handed access to the F row. The arrow keys have been remapped to FN + W, A, S, D, making navigation feel more intuitive and efficient. These updates maintain the sleek, minimalist look of the 60% layout while making it easier to use, especially for users across different platforms—whether you're on Mac, Linux, or Windows. VIA-customizable Beyond its striking design, the NOOIR CP01 is fully customizable with VIA. Whether you want to remap keys, set up complex macros, or create multiple layers for different workflows, VIA gives you the flexibility to tailor the keyboard to your needs.  Customize your comfort with the "socket" system The CP01 features a new structural design called the "Socket". At its core are custom shock-absorbing "positioning pins" that offer adjustable damping. These pins are arranged in modules, with each module holding 2 to 5 pins, allowing users to tweak the keyboard's feel from soft to firm. With 30 pins total, you can fine-tune the rebound strength in specific areas, making it as soft or firm as you like. Adjusting the feel is easy—just swap out or tweak the modules in the regions you want. Built to last The NOOIR CP01's aluminum case gives it a robust build that can withstand the rigors of typing and traveling. Weighing approximately 5.5 lbs (2.5 kg), it’s a hefty keyboard that’s designed to stay put, no matter how fast you type. Designed for comfort Typing should feel good—period. With an 8° slope and a front height of 0.87 inches (22mm) including the footpad, the NOOIR CP01 is designed to keep your wrists comfortable, reducing strain and letting you type longer. Long-lasting power Say goodbye to frequent charging. Equipped with a 4000mAh battery, the CP01 provides long-lasting power that keeps you typing or gaming for hours on end.

Orders placed in July are expected to ship by late August or early September. Compact CD player with jitter-free playback The SMSL PL100 CD Player makes it easy to keep enjoying physical discs long into the future. The built-in Cirrus Logic D/A chip is designed to pull detail from every recording, whether you’re exploring a well-worn jazz compilation or a new pressing. The PL100 treats your discs with care, and it handles the technical side—error correction, jitter reduction, stable playback—with ease. Decoding that brings out the details The built-in CS43131 chip goes beyond typical CD playback. It handles digital-to-analog conversion with precision, which means subtle bits and pieces in your favorite recordings have a better chance of coming through. High signal-to-noise ratio (110dB) and low distortion (THD+N of 0.001%) keep your source material sounding clean from start to finish. A second PLL that lowers the noise floor This player’s internal design leans on a second PLL (Phase Locked Loop) circuit to reduce jitter during CD playback. The result is a more stable clock signal that leaves your music sounding more natural.  Optical and coaxial outputs for more flexibility The PL100 comes with both optical and coaxial outputs. It does not decode MQA itself, but it easily passes a raw digital signal to your preferred external DAC that can handle MQA. The result is more freedom to customize your system.  Headphone output that actually delivers The front-panel 3.5mm headphone output isn’t just there as a courtesy. It offers enough power—60mW at 32Ω—to handle a range of headphones without breaking a sweat. Housing that’s easy on the eyes The housing is made from full aluminum alloy, which feels solid and helps with heat dissipation. The terminals are gold-plated, so connections to your amp or DAC remain stable over time.  Placement and control with a personal touch You can place the PL100 horizontally or stand it up on its side. Either way, it doesn’t crowd your desk or audio rack. The included remote offers full control at a distance. Browse tracks, toggle outputs, keep your seat—no need to fiddle with front-panel buttons.

Singxer SA-1 Fully Balanced Amplifier V2

An analog amp from a digital heavyweight Since 2011, Singxer has operated as an ODM and OEM in the audio industry as well as developed their own DACs and digital interfaces. Best known for their work in digital audio, they’ve made technical achievements in clock systems, phase-locked loop technologies, and more. In a bit of a departure for a company that so heavily favors digital products, Singxer has now released the SA-1, a fully balanced pure analog class A amplifier. Call it beginner’s luck or pure talent: Singxer has knocked this one out of the park. The SA-1 offers superb amplification, vanishingly low noise floor, and nominal distortion. It’s a great choice for anyone looking to graduate to a high-end balanced amplifier that can double as a preamp.  Fully independent Class A analog amplifier The Singxer SA-1 is a class A pure analog amplifier. Using simple circuits that draw the same amount of current and consume the same amount of energy whether receiving a signal or not, this is the most straightforward of amplifier types. It isn’t subject to electromagnetic interference caused by digital components, so its total harmonic distortion and signal-to-noise ratio are exceptionally low.  Seven inputs and outputs The Singxer SA-1 can be used as a headphone amplifier or preamplifier. As a headphone amplifier, it supports balanced XLR input, RCA input on the back panel, and three outputs on the front panel: 4-pin balanced XLR, balanced 4.4, and single-ended 6.35. As a preamplifier, it supports balanced XLR input, RCA input, and two outputs: balanced XLR and RCA.  Product highlights Fully independent class A analog amp Super clean output with low distortion and low noise floor Seven inputs and outputs Fully balanced architecture Headphone amplifier and preamplifier Amplification type: Class A Two gain modes: low/ high Version two includes upgrades to the PCB routing and DC performance.  Specs Inputs: Balanced XLR, RCA Outputs: Balanced XLR, RCA, Balanced 4.4mm, Balanced 4-pin XLR 4, Single-ended 6.35mm SNR: 126dB Dynamic range: 147dB @A-wt THD+N:  0.000078% @balanced input and no output load 0.000128% @balanced input and 33Ω output load Noise level:  0.66µV @ Max output, SNR / DNR 147dB 300nV RMS @ Low gain, A-Weighting, 20Hz-22kHz Output power 6480mW @ 32Ω 2000mW @ 120Ω 380mW @ 600Ω Power supply: 100-240V AC, 50/60Hz Low-resistance output impedance: 0.25Ω (balanced), 1.1Ω (single-ended) High-resistance output impedance: 10Ω (balanced), 11Ω (single-ended) Dimensions: 9.2 x 6.6 x 1.8” (234 x 170 x 46mm) Housing material: Aluminum Color: Black Weight: 3.9lbs (1.8kg) What’s included 1x Singxer SA-1 1x Power cable Featured Reviews "I don't want to listen on any other amplifier right now.

The trampoline-like construction flexes with your movements and cradles your head without digging in. Breathable and self-adjusting, it keeps things cool, stable, and ultra comfortable.  Stretches, flexes, and keeps its shape The TPU mesh material strikes a smart balance: soft, but not saggy; springy, but not tight. It adapts to the contours of your head while maintaining steady tension, so your headphones stay put. And unlike foams or fabrics that break down over time, it's built to last. It won’t stretch out, flatten, or fray, even after months of daily use. No tools required Step 1. Slip the strap ends onto the headband. Step 2. Done. No adhesive, no screws, no permanent modifications. This is a zero-commitment mod you can add or remove in seconds, whether you’re trying it out for the first time or switching it between headphones. Know before you buy This strap reduces the total range of vertical adjustment. If you already max out your headphone’s height adjustment, adding the strap will make them feel smaller. It’s best suited for users who have a bit of adjustment room left.
