About Jakub

I founded The Audio Stuff and personally write, listen to, score, and sign off every review carrying my byline. There's no rotating freelancer pool and no ghost-writers - every named writer on the masthead owns their pieces end-to-end, and the catalogue's consistency comes from a shared listening chain and a single published reference list that every score gets anchored against.

Outside the written pieces, video companions for the bigger reviews go up on the YouTube channel - same gear, same chain, same listening notes. You can reach me directly for review requests, corrections, or anything editorial via email, WhatsApp, or LinkedIn.

How Jakub tests

Every score on this site is anchored to a published per-category reference list, so a 7.6 means the same thing in every review Jakub writes. Gear stays on the chain for a minimum of two weeks of daily listening across multiple genres and sources before a verdict ships, and each piece is compared head-to-head against the reference for its price tier rather than against a memory of it.
