TotalDAC announce in-line filtered Ethernet cable


Electrical noise – it’s bad mmm kay?

Electromagnetic interference (EMI) travels into your home courtesy of your friendly electricity company. It’s also the result of your own foolishnes. That dimmer switch you installed might be great for creating an intimate late night vibe (boom chicka-wow-wow) when showing off your Captain Beefheart rarities but it’s sure as hell doing nothing to keep the electrical noise down in your home’s mains supply. Ditto those cheap-ass switch mode power supplies that recharge your smartphone, your fancy camera’s battery and your Dyson vacuum cleaner.

Then there’s the more insidious radio frequency interference (RFI). It’s EMI as a free agent, radiating through space. Got Wifi? Got a mobile phone? Chances are your home is swimming in RFI. It gets picked up by your hi-fi system’s cabling which acts as antennae to such airborne detritus. Oh dear.

Ultimately, this noise can travel along power cables and into your supremely sensitive, supremely expensive hi-fi equipment causing tiny voltage perturbations and increasing distortion (which is bad mmm kay?).


What to do? We’ve recently seen how LessLoss’s twisted DFPC cables can help mitigate noise entering gear that’s direct connected to the wall socket. Earlier this week we saw how TotalDAC’s D1 USB cable can filter (some of) the PC-induced noise to prevent it from reaching the DAC over USB.

But what about a network streamer connected to a router? It too could become a victim of noise generated by the router’s internal circuits and the switch-mode supply that powers it.

Mitigating noise along Ethernet cables is Vincent Brient’s latest target. He’s just announced an Ethernet cable with in-built filter.

“The RJ45 ethernet filter/cable is a TotalDAC exclusive that improves the sound of any DAC or music server using an ethernet link. The filtering of high frequency pollution improves the soundstage and makes the sound more natural.”, says the promotional blurb.

With number of network streamers on the rise this will undoubtedly be of interest to those looking to juice the last from their AURALiC Aries, Aurender X100L (both of which are slated for evaluation by yours truly), SoTM SMS m-100 mini server or Lumin S1.

Of course there will always be those who refuse to believe it can possibly make a difference whilst simultaneously declining an invitation to attend a demo. Them’s the audiophile breaks. The TotalDAC USB cable yields very real results against a backdrop of healthy skepticism, hands-on.ears-on experience that opens my mind to the Ethernet version bringing similar results, especially when triangulating experience with an Audioquest Ethernet demo earlier this year.

Two meters in length and weighing a kilo (!) the TotalDAC filtered Ethernet cable will run you €390.

One final thought: Those looking to plough the Ethernet sound optimisation field at the cheaper end might wish to consider the Acoustic Revive RLI-1.

    • By all means Justin. Contact Vincent Brient for a loaner and then report back in this here comments section.

      • May be tempted to try this. That said, I’ll need to do some research first and see what base cable they start with – and whether it’s certified in any way. Thanks for the heads-up.

  1. That’s way too light. I want 10kg/m cables. That way I can work out with them daily – rowing practice or something. Take that, Captain Beefheart!!

  2. John et al,
    The Acousence GISO isolator – – performs a similar function to the TotalDAC Ethernet cable and has been garnering very positive user reviews on the Linn server forum. There are two versions, a DS for home use and a GB for pro-audio applications. Prices are 249 and 349 Euros respectively. I have ordered a DS to use with my Antipodes DS server and Meicord Opal Ethernet cable. I’ll report back on the DS and it’s effectiveness (or not) in due course.

    • Yes please Andy – I’m confident many readers would be interested in your findings. My personal interest is rooted in what improvements (if any) it can bring to the Antipodes.

  3. I think I preferred it back when you said you didn’t review cables! Yes this is not a review per se but it’s not exactly an unbiased ‘news’ report either.
