Reviews for Tellurium Q Black II Speaker Cable - Factory Terminated

Having already fitted a TQ Blue II digital and TQ Black II XLR interconnect into my system, I decided on the black II speaker cables. They really were the icing on the cake, giving improvements from top to bottom.
I was concerned they might be too smooth sounding after reading some comments, but no, high frequencies were well extended but without any harshness.

The midrange is so much more detailed, with strong stereo imaging and improved depth. Bass also seems tighter and better extended but without any flabbiness or bloat. Even in my modest system, all these attributes were easily heard.

Highly recommended.

I had one from Amazon and upgraded with this.

Sound is clearly different - more transparent and dense in sound.

Moving up from a £90 pair of cables to these, I wondered if I’d notice a difference, but I needn’t have worried!

Life-changing? Earth-shattering? No! But a relaxed, controlled, clear soundstage that really opened up in front of my listening seat.

And as for clarity? Well, I played some of my favourite demo songs and clearly heard every word (for the first time in some cases!). But simultaneously, there’s no forced treble or boosted mid-range that could easily explain this.

The Celestion 66s (pre-Ditton naming) I refurbished during lockdown are finally singing!

These cables are just on it. As for burn-in, I had the 96-hour version, but they’re still getting better two weeks on.

I might have given these five stars if I didn't already possess the Blue IIs. But I do, and in my honest opinion, the Black II doesn't really merit the price -- not far off three times the cost of the Blue IIs.

I've transferred the Blue II's to my second, nearfield system in my study and now listen through the black IIs on my main system in the lounge, which uses my DIY Decware ZF15M open baffle clones.

In the nearfield system, they replaced my Audioquest FLX/SLiP 14/4s, which, n my honest opinion, are very good value and recommended for anyone wanting to bi-wire on a budget. With the Blue II's I used Blue II jumpers with my Quad S2 speakers, which are clearly better than the FLX's.

But what about the Black IIs in my main system? Well, everything people say about them is true -- better bass, better clarity and soundstage than the Blue IIs, etc., but like I said, I have my doubts about their price -- when the Blue IIs were pretty good too, and sounded a touch louder for a given volume setting.

Moreover, the Blue IIs have an extra, indefinable something that the Black IIs don't seem to possess. One YouTube reviewer (Pursuit Perfect System) pointed this out, too and said it was only an impression but that the Black IIs were better. To which I answer, it may be an impression, but I miss it with the Black IIs -- a certain sweetness and magicality. I'm not sure that the extra bass definition and clarity, which makes the Black II technically superior in most ways, makes the game worth the candle.

It was difficult to decide whether to get the black IIs or the custom-terminated ultra-blue IIs, which would have been considerably cheaper. Eventually, I plumped for the Black IIs and now wonder whether I made the wrong choice. Hey-ho, too late now. Don't get me wrong, the Black IIs are fine cables. It was just my misfortune to have gotten used to the blue IIs and now to miss the extra secret sauce of those in my main system.

I can genuinely appreciate what the Black IIs bring to the party, I just wish the Black IIs also had that extra missing ingredient, whatever it might be.

One other thing: I got the 96 hr. break-in, but that wasn't enough to get the best out of the black IIs, I don't think. Maybe 200-300 hours is a better bet.

I bought new speakers and still used my 12-year-old Xindac FS-1 cables.

Then tested some newer cables. The QED Genesis Silver Spiral is a great-looking cable with and lovely base and details. But some tracks sounded very thin, and I got ear fatigue when listening too long.

Then I tested QED Reference XT40i. Sounded ok, but some lack of dynamic, and I returned to my old Xindac cables.

I found this Tellurium Q Black II and got a better soundstage and less bass. The instruments sound more natural, like the kettledrums in Totos. I remembered the old cables added bass to the kettledrums, but with the Tellurium, it's gone, and It's easy to hear them through the whole song.

More detail and naturalness to instruments and more details and sounds I haven't heard before in songs.

I have problems with ear fatigue. All cables that are too dynamic and analytical make me nervous.

There are more precise cables, more dynamic, with deeper bass and higher frequencies, but if you want a cable with a pleasant tone, deep and wide stage, full tone but high separation, this cable is for you.

It doesn't fascinate at first listen, but after a while, I can't listen to anything else from my cable collection (Chord Epic X, Chord Shawline X, Nac a5, AQ Rocket 11..). On the other hand, it is not for those who want to make their system more dynamic, analytical and attractive at first (for that, I recommend Chord Epic X).

Short and sweet. This cable made a huge difference!

The bass was tighter, the treble sweeter, and there was more detail. I wasn't expecting that much change over my previous Van den Hul cable (that cost pretty much the same).

I highly recommend it - Black magic!

I have tried more expensive cables, but the Tellurium Black II sounded amazingly transparent, with taut Bass and a very clear midrange after the initial burn-in.

Overall the sound was recognisably fluid. I felt the difference even compared to more expensive, award-winning QED cables, which were my favourites until I tried these Blacks.

Futureshop, your communication, packaging and delivery are outstanding!

A big thank you!!

Best value for the money. The dark background and musical dimension are so clear! The sound was neutral.

I bought this cable to replace the Tellurium Q Blue, it's distinctly more neutral/natural sounding, and I consider it a good upgrade. If, in fact, you are considering the Blue, and you are able to, I recommend spending a little extra for the Black II.

Interestingly, the Black II is a slightly smaller cable than the Blue.

Big shout out to Mark in customer service for his excellent support and recommendation.
