Pros
Delivers a lower noise floor with more detail, speed and bass slam than a less expensive reference cable.
Improves spatial precision, with instruments and voices anchored more convincingly in the soundstage.
Can make well-matched components sound more effortless, resolved and dynamically capable.
Cons
Its substantial build makes it less flexible than the lighter Silver cable.
At more than £2,000, it is a serious expense and only makes sense in suitably capable systems.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 92/100
Reviewers describe a clear improvement in transparency and low-level detail, with the noise floor seeming to drop and the music flowing more effortlessly. They also report stronger bass slam, better speed, and a more palpable sense of instruments and performers in space.
Transparency Resolution
93/100
The review says the noise floor dropped and that more detail came through from familiar tracks. The cable is also credited with a more resolving presentation, letting the system sound more open and revealing.
Tonal Balance Musicality
90/100
The presentation is described as more effortless and musically free-flowing, rather than simply sharper or brighter. The reviewer frames the change as an across-the-board improvement in musical involvement.
Dynamics
92/100
There is a stated increase in speed and bass slam, along with the sense that the amplifier had gained volume and resolving capability. The system is said to sound more forceful and capable under playback.
Soundstage Imaging
93/100
The reviewer says voices and instruments were palpably in the room and that guitars, bass, and drums were anchored in place. That points to stronger image stability and a more convincing spatial presentation.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
84/100
The review focuses on the cable’s heavier construction and its role in the system, but says little about long-term durability or engineering details. Functional commentary is mostly about the cable’s apparent ability to let the connected components perform at a higher level.
Value for Money
88/100
The reviewer is clear that this is an expensive cable, but also says it can extract the performance a system is truly capable of and may be the best bang-for-buck upgrade in the right context. The value case is strongly tied to the size of the audible improvement rather than to low price.

Manufacturer's Description — Tellurium Q
The final piece in the puzzle for the Silver series of power cables. It has some of the “magic” of the Statement power cable because it came out of that same research and so is a smooth performer that brings your system to life. Which is relatively meaningless until you hear just what they can do for your system.
Warm and forgiving for systems with a slight edge or for those who like a more smooth laid back presentation. Blue and Ultra Blue are especially good for AV and home cinema.
Smooth, fine detailed and great resolution while actually reducing apparent harshness. Music is presented as a coherent, organic whole, with a jaw-dropping sense of realism and naturalness.
Totally uncoloured, acting as a wide open channel sounding unforced, vivid and dynamic with phenomenal resolution, transparency and natural tonal colours. All this while sounding extremely analog and coherent, from the exceptional top end extension to bottom with finely detailed, separated bass notes.
