Shunyata Delta X Power Conditioner

Shunyata’s Delta D6 has been a popular power conditioner here at Audio Therapy over the past few years. Originally released in 2021, the D6 was one of their mid-level models and it always made a positive impact when added to a system.

Fast-forward to 2026 and Shunyata’s X revolution is in full swing with their X power cables going down incredibly well. Plus, the flagship power conditioner the Everest X was something of revelation when it launched in the summer of 2025. Shunyata have been quietly working on a replacement for the Delta D6 for a little while now. I was advised in Munich last year that this new model would be called Delta X and that Shunyata were planning on pushing performance levels well past the D6. I’m thrilled to announce that earlier this week I took delivery of the very first Delta X to arrive in the UK.

The Delta X is a little wider than the Delta D6 because it has gained a seventh socket, making it even more flexible for those with larger systems. There are six sockets organised into three zones (two sockets per zones), with the seventh socket in a zone by itself.

This zoning allows great flexibility to maximise performance by keeping analogue and digital components isolated from one another. Component-borne mains noise is commonplace, but this zoning prevents this noise from interfering with other connected components.

Anyone vaguely familiar with Shunyata’s range of power conditioners will no doubt have heard of the QR/BB module. This patented technology has, to date, only been found in Shunyata’s bigger, more costly models (like the Typhon, Denali, and Everest). This module acts like a large reservoir for storing current and delivers it instantaneously as and when the system demands it, delivering large amounts of current much faster than a direct connection to a wall socket can provide. It really does give any system incredible headroom and dynamics and is a key Shunyata technology (QR/BB Patent Number: US 10,031,536).

Another Shunyata patent which used in the Delta X comes in the form of their Noise Isolation Chamber (often referred to as a NIC), this chamber reduces high frequency power line noise and does so without any of the reactive negatives associated with transformers and large capacitors as used in conventional power conditioners.

As with all Shunyata power conditioners the Delta X also has a chassis ground terminal, designed to be connected to the Altaira (or Altaira X) Ground Hub which can further enhance system performance.

Given the increase in price from the Delta D6 to the Delta X, combined with the additional technologies that have been implemented, I was expecting great things from this new model and it certainly doesn’t disappoint.

I still have a Delta D6 here so I could make a direct comparison between the two models and it didn’t take long listening to appreciate what this new model was delivering. System dynamics and resolution were instantly improved, as was bass articulation. Spatially, there were also improvements to the system that I was using (Soulnote A2 Ver 2, Metronome DSS 2 Streamer, DSc Mini DAC, and a pair of OePhi Ascendence 2.5), the soundstage developed greater width and also front to back depth. The drop in noise levels give the system greater nuance and subtlety.

It’s an upgrade which benefits an entire system, which is one of the reasons why it can make such a transformative improvement to overall performance, although it’s important to stress that a system needs to be in a good starting place. You can’t make a silk purse from a sow’s ear.

I’ve already got a waiting list of customers wanting to test drive one and I’ve a feeling it may do rather well. For the asking price of £4,995, the Delta X is lot of power conditioner. I would argue that it’s actually closer the Typhon T2 than it is to the Delta D6.

As I alluded to above, the Delta X is quite wide, measuring in at just over 53cm, so if you are interested in adding one to your system I’d double check the width of your equipment stand, that seventh socket does make an impact.
