When I first reviewed the Silver Complement4 headphone cable, I didn’t think a cable could get any more transparent and honest. It was my reference cable for nearly all of my reviews. A few months later Peter Bradstock announces his masterpiece…the Prion4. Without hesitation I purchased a pair with all the upgrades and couldn’t wait to test it out. I was initially hesitant about purchasing the $999 Silver Complement4 but immediately jump on a $1,799 cable. This should speak volumes about the quality of Peter’s products. He doesn’t mess around and this Prion4 is his passion project.
“Prion4 is a substantial upgrade over the highly proficient Complement4 Silver. Despite its extreme nature, the thickness of the Prion4’s four cables are only 13% greater than those of Complement4.”
Without getting into all the technical details, I’ve decided to compare/contrast a few high-end headphones with the stock configuration to give listeners an idea of what the (albeit pricey) upgrade will give you.
Shifting the format a bit here:
In all cases, the Prion4 will take your headphone from horse and carriage to a first class flight. Enough said.
Owners of the Silver Complement4 would be curious as to what benefits an upgrade to the Prion4 will do. This is a list of things the Prion4 does better than its little brother:
The Complement4 is a beautiful sounding cable in all regards. It’s tonally balanced, detailed, smooth, and honest. The primary benefits for the Prion4 is a much, MUCH more holographic sound, more details, apparent micro/macro dynamics, better layering/separation, blacker background, and better coherence/PRaT. I know it’s cliche, but comparing the two is like comparing upscaled DVD and Blu-ray.
The Prion4 doesn’t sound like what you’d expect from a silver cable. It is probably the most transparent and detailed cable I’ve ever had the pleasure of listening to. It has this uncanny way of keeping the musicality and coherence while delivering a very dynamic and involving sound. I’ve found they’ve improved the Focal Utopia, HiFiMAN HE-1000 V2, and Abyss stock cables enormously. They were also a significant upgrade from the Silver Complement4. The only small negative I could come up with is it’s slight lack of warmth. Previously, I thought it had a bit of sheen in the mids but it turned out to be a problem on the source end (an ethernet cable of all things). Although unnecessary, warmer gear and a tube stage would definitely harmonize well with the Prion4. It would really give the listener a more lush presentation without losing the detail and soundstage. From all the cables I’ve heard so far, the Prion4 is the only one capable of giving you the best of all worlds.
Those in the industry know that Peter is very keen on building these cables himself or with his wife. He always uses the best materials and is a perfectionist when it comes to cables. Did I forget to mention that this is the most beautiful cable I’ve ever set my eyes on? I don’t really care for aesthetics much but I had to pause and appreciate the craftsmanship of this cable. It feels and looks beautiful.
If the recording has nuances and details that are left to be discovered, the Prion4 will do it quick and in graceful fashion…without being clinical or harsh. It will bring new life to your recordings and provide a very convincing, transparent, and balanced sound. I wouldn’t be surprised if this is the reference cable for most headphone reviewers out there. The Prion4 is truly a remarkable achievement in the headphone space.

Can I ask which other aftermarket cables have you tried with the Utopia and what was your DAC and source?
Thanks in advance.

Hi Jay,
Love your site. A frequent reader.
Nice review of these cables. I too have a Dave and would like these cables with Focal Utopias. I notice in the first image that there is an interconnect between the DHC Prion cables and the headphones. Is that a necessary interconnect? Would be nice to plug 'em in directly.
Could you comment on cable ergonomics, such as cable stiffness/flexibility/weight?
Hey Bill! The adapter isn't necessary if you get the cable specifically for the Utopia. I use these cables for the Abyss so required an adapter. The Prion4 is a tiny bit less flexible and more weighty than the Complement4. I personally didn't have any comfort issues with it. These cables are so meticulously built. Hope that answers your question!
Definitely does. Thank you. Now have to decide between Prion4 and Danacable Reference Lazuli. Another person I respect has also recommended the copper route for Utopia headphone cables, but I'm inclined toward silver.
If you prefer more of the silver sound, you won't like the Laz Ref. Stick to Complement4 or Prion4. I may actually have a Complement4 for sale. Let me know if you're interested.
You did a mighty nice review of the Prion4. Thank you, though.
Hi Sir,
Great review. Lot of insights. In this price point, is there any other better headphone cable that is better in performance than this? Between trinity helix vs prion 4 headphone cable upgrade - which one is better in terms of sound improvements? Thanks
