Video Description
Do you really need a master clock for your hi-fi setup? Or is it just another audiophile upgrade that sounds better on paper than in practice? In this video, I explore what a master clock actually does, why some listeners insist they can hear the difference, and whether it’s worth adding one to your digital audio chain. I’ll be talking about the S.M.S.L G1 master clock, working alongside the S.M.S.L PL200 T CD transport and D200 DAC. We’ll look at how clock synchronization, jitter, and timing accuracy can affect your sound — and whether any of it really matters once the music starts playing. If you’re into high-end audio, DACs, or digital timing, and you’ve ever wondered whether an external clock could make your system more precise or just more complicated, this one’s for you. Links to the gear are below, and keep an eye out for the follow-up video where I’ll put the G1 to the test in a real system.
