HDMI & Optical Cables That Actually Matter

Apartment Audio Lab Editorial Cables Reviewed

Quick verdict · Cables

Buy a certified Ultra High Speed HDMI (6 ft) for TV → bar eARC, and a boring TOSLINK (6 ft) when you need optical. Skip audiophile markup.

Apartment runs are short. Expensive HDMI does not make eARC dialogue clearer. Optical does not need mystical jackets for PCM stereo. Certified length that seats firmly is the whole job.

HDMI picks (apartment runs)

Primary — Ultra High Speed, 6 ft

Certified Ultra High Speed / 48Gbps class. Overkill for dialogue-only eARC on a 6 ft TV→bar run, but it is the honest certified default when you want one cable that will not under-spec video later.

Value / myth-kill — High Speed with Ethernet, 6 ft

18Gbps High Speed is enough for ARC/eARC audio on short apartment runs. If someone is selling you a $40 “audiophile” HDMI for clearer voices, this is the honest cheap counterexample.

Optical / TOSLINK picks

Primary — Digital optical, 6 ft

Working fiber ends + tip caps. Use for older TVs without ARC/eARC, optical backup, or streamer → bar topologies on the wiring guide.

Length alt — 3.3 ft (tight units only)

Same Basics TOSLINK class when the streamer and bar sit close in a small entertainment unit. Prefer 6 ft unless you know you need short.
