Ultra Black Speaker Cable

“Tellurium Q Ultra Black is the cable we wanted to make from day one. We told our UK distributor what to expect as we handed them a prototype that looked more like a fireman’s hose and less like a sonic phenomena. They glanced at the heavy, stiff and it has to be said ugly brown experiment. “Yes, well we will give it a go and take it to a few dealers to see what they think”. Later that day we get a phone call from our disbelieving UK distributors at Kog Audio, “what the hell is in it? We’ve never heard anything like this!”.

They took it on trust that the production version would be incredibly thin and flexible by comparison and look a whole lot better. So Kog Audio put in an advance order that day without needing to see or hear the production model because, in their words, “if it is even quarter as good as the prototype it will blow people away”.

We think that the production version sounds better than the prototype.

At first glance you could be forgiven for thinking that the Blue Diamond and Ultra Black were the same cable with different printing but when you plug the Ultra Black into your system there is absolutely no doubt that the Ultra Black is in a totally different league.”

HiFi and Music Source

“It is hard to understand what has happened here, the last few weeks of exposure to Tellurium Q have changed my perception of HiFi and what can be achieved.”

“It is this further extension of flesh-and-blood tangibility to vocals, guitar/bass fretwork, timbral colour and dynamic inference offered by the Ultra Black II which sets it apart from its brethren; it simply helped put performers in the room.”

“Vocals and music are in three dimensions that frees speakers and leaves only sound, mood and atmosphere. The speakers disappeared.”

“To be honest, sometimes I do struggle to hear meaningful differences between one brand and another or one model and another within a manufacturer’s offerings. However, I was genuinely taken aback when I first installed the Tellurium Q Ultra Black II speaker cables.”

HiFi Plus

“the performance of the Ultra Black II is not skewed by materials or shaped by pseudoscience; it stands of falls on its sonic properties. We found that, “the character of the speaker cables is distinctly pacy; this is very much a rhythm-oriented cable, where timing is given top billing regardless of the music being played. And this makes it very engaging and powerful; my foot started tapping of its own accord and I found myself swept up with the groove on all manner of tracks.”

“When playing the best live recordings, the Tellurium Q cable was able to convey the acoustics of the venue and vivid reactions of the audience in a very convincing way deepening the feeling of participation in the event….. I believe that for many people the Ultra Black II may be the end of their search for a still reasonably priced, high quality speaker cable”

“If you have the original Tellurium Q Ultra Black then this update might take you aback. It doesn’t just improve on the original it takes the sound on in leaps and bounds…… I heard the same effect on every track I played – leading me to believe that there is something special going on with these Ultra Black IIs….Tellurium Q’s Ultra Black II’s can be see as one of the best loudspeaker cables on the market at their price”

“It was like when I upgraded my TV from an HD LED set to an Ultra High Definition 4K set. The differences were stunning…..What I can state is that the Ultra Black 11 cables are currently the best I have heard in my system

The Ultra Black II’s allow our ears and brain to work as they would in a live environment picking out every nuance and sound cues to create that actual experience, not a close approximation. Let’s just say I was hearing so much more into the performance. I genuinely was hearing microscopic details I just didn’t know we there before”

“However, whatever it is it works wonders. I have yet to hear a speaker cable which delivers timing like this one. I cannot quantify scientifically the difference between the two generations but if pressed I’d say they are 30 to 40 percent better. That is a big leap in performance.

A good friend of mine manages a well respected retail outlet in South West London, and gave me a lot of invaluable advice and guidance when I decided to get a Linn LP12, which I did last year. When I told him what I was reviewing he said “Good, now you will find out just how good that LP12 really is!. He was right.”

“The extension is incredibly clean and natural and I must say that I didn’t manage to find that in another cable until now… I’ve been listening to some live recordings which were incredibly real, from the sounds in the audiences, to the voices and instruments on the stage. Even the clapping was hauntingly lifelike, putting me right there in front of the audience.”

Inner Magazines

“So what is it that the Tellurium Q’s do and the other cables not? Or do but only to a lesser extent? They are damn musical, for one thing. Second, they appear to diminish harshness of the digital sources. Third, they let the midrange shine. Fourth, they keep the low bass frequencies well under control. Not bad for a pair of cables.”

– Kai Ekholm, inner-magazines.com

Cable sceptics

“… things seem to start and stop when they ought to and this adds to what I can only describe as a sharper aural image. Clarity is the only word I can really find to describe the effect of these cables”

Performance Profile

Blue Family 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

Black Family 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.

Silver Family 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.

Way too small with very little stretch.
I ordered a size 4X to make sure they were loose enough. The ones I received are like a size 8 very small.

If you haven't switched to boxer briefs, you're missing out :)
Size: 11 Plus, Color: Microfiber - Colors May Vary
I figured I ought to provide a review, something I'm not prone to doing even though I often/always bank my purchases on item reviews, since I just bought me a second set of these underwear because they're just that good! I bought my 1st set of these 2 months ago because I was on the hunt for some new comfortable underwear and omfort was my main criteria. Wasn't aware that I was dealing with some health issues that was causing a fair bit of internal inflammation, just knew that I had had enough of basically everything I had at the time because they were old, ratty looking and even my all-time favorites had begun feeling too... something... not exactly too tight, yet they just weren't very comfortable anymore either and I didn't need that kind of extra stress in my life. But. I'm a barely-makin-it domestic violence survivor. Sure, I'm super proud to have gotten as far as I have in this world (considering that post-separation psychological terrorism and torture continue to thus day, 5 years after I broke free) but, by rights and family-rearing, I should be living in a whole different world right now... which is my way of saying that money is extra, EXTRA tight in my house...and yet, I still have "caviar tastes", ifykwim. Lol. And, frankly, neither I nor anyone else should have to scrimp on comfortable, classy-feeling, fashionable clothing no matter how small our clothing budget may be. I was spurred to check out boxer briefs for women after reading about a few different women's favorite brands in the comments on soneones IG post (that must have been in regards to underwear, but heck if I can remember the details). So, off I went to scout around on Amazon to see what this "boxer briefs" business was about... desperately hoping that the term was not just a rebranding of those "hipsters" things. I am 46yo, 5'10" (potentially closer to 5'11"... not something I care enough about to know for certain, lol) and, clothing size-wise, my whole adult life I have consistently been a 16-18/18-20, top to bottom, with a shape that seems some what apple-ish at the moment but has, in general, always been more hourglass than apple. Also it seems as if I might have rather freakishly high hips, lol... not really, but for reference, when it comes to pants or jeans what generally passes as "tall", usually a 33"-34" inseem, fit like ankle or cigar length pants on me. But evidently I don't just have long legs, no, this momma's body seems to also have one heck of a long, tall pelvis which I did finally measure to figure out for sure but, prior to that, I could tell based on the way that low cut underwear like bikini & hipsters, and any form of low rise pants, barely make it north of my low lying c-section scar location which, for those who can't relate, is basically at the top of my hooha or just at the point where my belly and my hooha meet. And because that point on my body is not even remotely close to my "hip" area such items basically fall right off my body unless they're super stretchy and I deliberately hike them up to my hip area which I put up with in my 20s and 30s, for the sake of fashion I suppose, but which was and is quite ungodly uncomfortable, and... basically... I am so over with "uncomfortable" anything (men included, lol.) In both cases I bought size 11, though, if I'm being honest, I am certain that a 10 would have fit well, too. And who knows, a 10 might have been just as comfortable or even more comfortable than the 11... but, I didn't take bother taking the chance to find out when I ordered my second set because the first set (size 11) made me so unbelievably happy that they literally changed my views about underwear for life. This whole "pants come off after work" thing or the memes about people working from home (due to covid restrictions) and not wearing pants never jived with me prior to having these boxer briefs, but now... omg... these things are super inexpensive and somehow still suit my somewhat "caviar taste" perfectly (have a good handfeel and are just so unbelievably super comfortable), PLUS... they're opaque and they basically fit (and look) like I'm wearing a loungy pair of bike shorts, so... yeah, I've spent some time over the last 2 months actually chillin in my house in my freaking underwear!!!! Life. Changing. :D
