Isotek Evo3 Premier power cable for MacMini


Press releases. Sometimes news of fresh meat comes direct to my inbox, after which the game isn’t one of copy-and-paste regurgitation. Key points have to be digested and disseminated. One can only get to the meat of the product announcement by stripping away marketing department spin. Think of it as skinning, gutting and then de-boning. That leaves us with only flesh.

Other times, you gotta do it yourself: a new product simply arrives on a manufacturers website. It’s ready to ship sans fanfare – and the mountain must go to Mohammed. When English isn’t the first language of the manufacturer’s copywriter, the lines between marketing department hyperbole and cold hard specification blurs. Doubling one’s digestion with a cerebral Alka Selzter usually yields results.


Alternatively, the facts get laid bare but visuals are thin on the ground: product photos are scarce or don’t meet the minimum 700px width specification for DAR. That’s precisely how news of the MacMini version of Isotek’s Evo3 Premier power cable arrived. Specifications were long – reproduced for you in edited form below – but photos were DOA.

  • 40 Silver plated 99.9999% OFC strands form three 2mm2 conductors set in a parallel construction with slight rotational twist
  • Teflon FEP dielectric (insulation) offers chemically inert and very low dielectric constant over a wide frequency range.
  • Cotton filler gives internal strength and reduces microphony
  • 10mm diameter PVC outer jacket gives a high degree of flexibility and mechanical strength
  • Terminated with IsoTek’s bespoke moulded connectors that feature 24ct gold plated OFC conductors
  • 16A rated
  • Standard 1.5M length only. No custom lengths available

The rationale behind Isotek’s entry-level cable reacquaints us with an old foe: electrical noise (EMI and RFI), rejection of which is the modus operandi of the LessLoss DFPC. However, Louis Motek’s cords aren’t terminated with MacMini-compatible plugs. Yet.

The terminating plug is the Evo3 Premier’s point of difference. Since ditching the external power brick in its 2010 regeneration, the Apple MacMini has run with an internalised power supply connected to the wall via a ‘Figure 8′ power socket.

The MacMini-terminated version of the Evo3 Premier is enjoying 24 hours at DAR HQ for a photo shoot, nothing more. Thanks go to Geoff Blundell at Tweed Heads’ Toma Audio for the loaner.


Eager beavers ready to pull the pin on a purchase should first observe how the Isotek’s terminating plug obscures the MacMini’s ethernet port. This will necessitate either a move to WiFi (an audiophile ‘no-no’) or the purchase of Apple’s USB Ethernet adaptor.

The big surprise here is that with the MacMini being so widely used as music server/streamer, the likes of Kimber, Cardas and Audioquest haven’t filled the need for an ‘audiophile grade’ power cord sooner. Of course there’s potential for a gotcha if the MacMini’s intestines generate their own electrical noise for which EMI obsessives are then pointed to the TotalDAC D1 USB cable.

So here it is – the Isotek Evo3 Premier for the MacMini. AU$200 in Australia, £95 in the UK.

  1. Hey Darko maybe this is more an email question since your sight doesn’t read like “cable guru” but maybe there are some readers who’ve won this battle.

    I just dropped significant cash on new front end, amp, and transducers for both my head and my house. Luckily I recouped about 60% on the gears that were rolled.

    I am looking at cables and from an aesthete point of view am inclined to just buy one brand, one series for everything… Interconnects, power, USB, digital, adapters… The whole 9.

    Is there a risk of “too much of a good thing’ by tethering everything with something like say silver? I lean towards dark and warm with my gears so figured silver in betwixt would help lighten things up.

    the idea of researching cables seems like an utter nightmare.

    Any idea of good one stop shopping for knowledge resources from cable gurus? I am at a loss.

    • You’re right, it can be a bewildering experience – the paralysis of choice! Your first stop though should be Blue Jeans Cable: no frills, cheap as chips but well made cables that get you off the bottom rung – and BJC do the everything except power cords: USB, digital coax, interconnects, speaker, LAN. Delivery is super-speedy too. After that, I’d advise you arrange loaners before committing more cash and perhaps even then only upgrading one type of cable at time so you can slowly appreciate the benefit. Some companies like Morrow offer attractive trade-in programmes that are worth capitalising on.

      Some people swear by silver, others swear at it. Consider the tonal balance of your system but don’t try to ‘correct’/EQ it with cables. If it’s too bright, don’t think that copper will tone it down.

  2. “the Isotek’s terminating plug obscures the MacMini’s ethernet port”.
    ???? What were they thinking, didn’t they test this product themselves?
    Totally ridiculous!

    Well, a better option for reducing RFI on the powercable that comes with the Mac Mini is this…
    just use a Ferrite clamp with a cable diameter of 7mm. close to the figure8 connector and all will be fine.
    Also if possible, make cable shorter (with new wall plug) which leaves no cable clutter.

    (just my 2c of tips&tricks)

    • Thanks Wilco. Got a link to the Ferrite clamp so readers (and I!) know what it looks like? I don’t see the Isotek cable as ‘ridiculous’, just that like any other product one must be aware of its compromises.

  3. Yeah that C-7 plug is way too beefy. I had discussed a Kimber WattGate product with Nate Mansfield about 2 years ago but at that time they were not interested in that product offering.

    There are a couple other C-7 offerings in this space as well that might help your readers. First there is the Oyaide PA-22 ZX:

    And then AudioQuest has 3 offerings in the NRG line:

    I had the Oyaide, but for most of my small electronics devices I am just using tidy 3 ft. Monoprice cables for under $1. Their not shielded but the short length helps with voltage drop, and prevents slop keeping the cable from laying over signal, speaker, or other power cables. For a Line Magnetic tube amp I am using a 3ft 14 gauge cable and a C-7 adapter like this:

  4. I liked the idea of a bunch of ViaBlue cobras slithering around on my sound system (Superficial I know but I am who I am) but the whole package started inching towards a grand…. I can’t justify that.

    But the idea of piecing it together… I hate the internet and what it affords me… Access to boutique brands and shops in China or Germany or some one man operation in Romania. It’s all just a few clicks away… it can get to be too much.

    Solid advice. Keep it simple. Blue Jean seems like a good way to go.
