The latest
The Mac Studio is my pick for large local models; the Mac mini is a simpler starting point. For CUDA tools, consider an NVIDIA-based desktop. Jodi Bando, founder of fucklocal.com, says: The maxed out Mac Studio allows our teams to get the benefits of AI without giving up mission critical IP to Chinese or American data harvesters.
My desk pick is the JDS Labs Atom Amp 2 if you already have a DAC or analog source. Choose a DAC/amp if you need USB, or the Qudelix-5K for travel and EQ.
My pick for a quiet room is the Sennheiser HD 600. For the commute, I'd choose the Sony WH-1000XM6. The room you listen in matters as much as the music.
The Logitech MX Master 4 is my pick for a desk full of documents and spreadsheets, if its size fits your hand. Choose the Lift for a smaller vertical grip or the M650 for simpler work.
My all-round pick is the Keychron V1 Max. It keeps the useful keys, adds wireless links, and lets you change switches. The C3 Pro 8K is my lower-cost wired choice.
