Minimum speaker cable length for TQ black to use with DAC V1+NAP100+Neat SX2?

Posted by: Tweed1234 on 11 February 2016

Have just changed speaker cable from NAC A5 to Tellurium Q Black in my main system - after a suitably long period of run-in they have done wonders to my Focals and SuperUniti.  

Am now going to do same to my second system - I've heard the 3.5m min length only really applies to NAC A5 - and particularly does not apply to TQ Blacks.  I only really need a 1m pair in my media room, and it would be nice to not have cable clutter (and save some money as well). Does anyone here have any experiences to share?

I wasn't aware of TQ doing such dirt lengths?

Yes you can buy TQ black by the m. 

There is no mention of required length in the manual for the Unity range. Just that they be the same length. 

TQ black has similar specs to the NAC A5. For optimum I guess you'd go with the usual 3.5m pair. But again, as no specific length requirement is mentioned in the manual (and it is for the other amps) it should be ok. 

Personally 1m too short for me. Min id go for is 2m pair

I would agree with finkfan, as far as I am aware their is no length restrictions with TQ speaker cables

Buying it by the cm would make the diamonds more achievable though Wenger!!

Can I have 50 mm please? I have a feeling Geoff merrigan might say no....

There is a small part of me that hoped for this answer just so I can
justify buying a shorter length of Ultra Black.

I currently using 3.5m of black. Depending on the position of my rack when I move things around, I may get away with shorter lengths too. UB is a big step up!

I am currently using ultra black, you certainly will not be disappointed if that's what you decide to go for.

I have to admit Wenger the UB is the best cable I've ever heard!

The TQ blacks made me want to throw away the NACA5s. Now really tempted to
get a short pair of UBs now for my second system just to try it out - but
would be nice to know that it won't blow up my nap 100.

The TQ blacks normally have the Nac a5 for breakfast most mornings ...followed by the SL' .......

The Nap amps do need the 3.5m unfortunately. It's due to the capacitance and inductance of the cable. No found any specs on UB cable.

I do think it depends on what speaker you are using. I tried TQ Black on my Naim IBLs and it didn't work at all. I put the A5 back on very quickly. And yes, it was a run in 2 x 5m length of TQ. I do use TQ Black interconnects between my DV75 phono amp and NAC282 and that seems to work fine though.

I'm sure you are right.....sometimes my sense of humour gets the better of me..

I wouldn't go shorter than 3m or 3.5m, just to be on the safe side. Nor would I use TQB with Naim speakers.

I've been using 1.5m lengths of TQ Ultra Blue with my Nait 2 with absolutely no problems for 8 months now. The newer amps are supposable more tolerant. (not saying my Nait 2 is one of the newer amps.....)

 

I did run my UQ2 with 2m runs of TQ Blue a year or so ago. Checked with someone at Naim and they said 2m would be fine.

I used UQ2-Nap 100 combo with dealer throw away Supra speaker cables for about 2-3 years with no issues whatsoever. Cable length was about 2 meters if I am not mistaken. Now I have NACA5 with that combo 3.5m per side. I heard from my the then dealer back in HK that new Naits and Naps are much more tolerant compared to the older ones when it comes to non-Naim speaker cables as well as lengths.

Nigel you started the TQB buying craze. If TQB sounds better then why not use with Naim speakers? I realise Naim speakers were designed with NACA 5 but it doesn't mean they are the best solution in a given system.

I used 3 mtr pairs of Chord Rumour 2 and the cheaper Chord cable with no problems what so ever.  I also tried 2* 5mtr runs of TQ Black on my Nap 100 and again with no problems.  In my experience TQ speaker cables and interconnects work brilliantly with Naim amps and Focal speakers - probably the best vfm upgrade I have ever made

The TQB was miles better when I had PMC speakers, but when I got my SL2s I compared it with A5 and preferred the latter. Maybe it's about the connectors and not the wire - I don't know. Nowadays I have the SL cables, which are better than both A5 and TQB, though somewhat pricey. Luckily 3m is just long enough.

If they were honest enough to publish the electrical specs for their cable we'd be able to answer this question.

Without that information any answer is a guess.

Posted on: 12 February 2016 by Finkfan

I don't think it's a question of honesty. If I had patents pending on something I designed that was brilliant, I highly doubt I'd be giving away any specs either. 

It's easy enough to get them anyway. Just need an LCR meter

I got a great answer from Tellurium about the 3.5m minimum rule for the TQ Ultra Black - 

"I would very much like to say buy 3.5m (it would be financially better for us) but I understand that modern Naim equipment have varying lengths of our cable attached and we have never had a problem reported to us. Naim obviously know the design parameters of their equipment better than we do so we cannot advise against their recommendation."

which I think is fair.  It would seem that no one, including TQ, has anything going wrong with shorter lengths - but that obviously doesn't preclude the possibility.  

If I go ahead and end up toasting my NAP100, I'll let everyone know!  It'll be my excuse to get that NAP 250.2.

I'm not 100% sure but I thought you may have to connect one end, red and black, together and put the meter across the other end?? Try that Lola and give us the results

Posted on: 12 February 2016 by Huge

If the patents are pending then there's no problem as for the patent to be granted, the information must be place in the public domain any way - so why not publish it to help people understand and select their product.  If they are not publishing it, what are they trying to hide?

I don't own an LCR meter, and I don't want to have to buy the cable just to test it's electrical compatibility (this equally applies to the many other cable manufactures who also refuse to publish even basic compatibility information).

This information isn't only required for Naim equipment but for others as well, so unless they are going to publish yes/no compatibility tables for every power amp ever made, they are just not giving the required information for appropriate selection.  So why not?
