What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 93/100
Reviewers consistently describe the cable as opening up the music, lowering the noise floor, and making everything sound more coherent and easier to follow. They also praise the added focus, control, transparency, and tonal realism, with clearer instrument separation and more expressive vocals.
Transparency Resolution
96/100
The reviews repeatedly emphasize lower noise, greater clarity, and a more transparent presentation. One reviewer says it 'clarified everything' and made spoken word and music more coherent and digestible, while another heard 'tonal realism and transparency' with more information coming through cleanly.
Tonal Balance Musicality
92/100
Reviewers hear more natural instrumental identity and better tonal distinction, rather than a generic smoothing effect. They mention greater nuance in vocals, firmer bass, and a presentation that lets the music 'shine through' with improved rhythm and timing.
Dynamics
91/100
The cable is described as bringing better control, firmer bass, and more effective musical drive. Reviewers highlight improved timing, stronger focus, and greater impact from percussive details, though the comments are more about grip and liveliness than brute-force power.
Soundstage Imaging
93/100
The image is described as tidier, more separated, and easier to parse, with vocals opened up from the backing music. Reviewers note more distinct placement of instruments and a more emotionally communicative vocal presentation.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
85/100
The reviews focus on sonic changes rather than construction, so there is little direct commentary on build quality. The discussion does indicate a clearly intentional redesign over the original model, but the reports do not provide much detail about materials, durability, or mechanical execution.
Value for Money
95/100
Value is discussed very positively. One review calls it a 'giant killer' and both reviews frame it as tremendous value at its price point, suggesting it competes strongly against pricier alternatives.

Manufacturer's Description — Tellurium Q
Ultra Blue II looks pretty much exactly the same as the old Ultra Blue except for the “II” denoting the new generation cable. Plug in a burnt in Ultra Blue II after the old version and you will hear within seconds why we have upgraded this cable. The sound is fuller, more organic and better balanced in the whole range. The top end detail is still the same but everything else has risen to that performance level.
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.
