Do Expensive Cables' Incremental Performance Justify Their Incremental Price Tags? Gizmodo Labs Weighs In

June 15, 2007

As one who’s regularly criticized so-called ‘premium’ cabling for digital HDMI, analog amplifier-to-transducer, and other source-to-destination interconnects in the past, I’ve been following Gizmodo’s recent back-and-forth with Monster Cable with great interest. The so-far links:

The perhaps-obvious conclusion; if impedance or other variances between inexpensive and premium cabling do exist, in and of itself a questionable stance, they only manifest as quality differences (signal degradation for analog cabling, and more binary behaviour for digital interconnect) at extended cable lengths that aren’t applicable to most consumers’ setups.

This interpretation of the data is only valid, of course, if you trust Gizmodo’s lab skills….which may be yet another questionable stance. I’m not going to ‘ding’ them for running the tests at Monster Cable headquarters, although their non-neutral venue selection does give me pause. However, I don’t necessarily agree with some of their definitive ’fail’ verdicts on the inexpensive cabling, since the ability to discern an admittedly collapsing signal ’eye’ is receiver-dependent (and, of course, the ability to drive a high-quality signal is transmitter-dependent….Gizmodo’s study is clearly not statistically significant). Your thoughts, folks?

Good receivers can discern the correct digital signal even when the EYE is closed... an HDMI 'fail' is not a SIGNALING failure at all. A quality receiver will get around all of the EYE diagrams shown. As for Gizmodo's study not being statistically significant - they had to pick representatives of the price categories. Not having a large number of candidates is not an issue here.

It is either the receiver and/or the transmitter. Depends on how the receiver or transmitter handles the cables medium characteristics and how it impacts the analog signals frequency components. Similiar can be said of digital signals. So issues of equalisation, amplification; how harmonics and subharmonics are handled.
