Now I wonder if BNC connectors were making any differences?

The rearTWIST UHD BNC connectors are specifically designed for high resolution video signal transmissions. Due to the unique insulator and contact pin design, the connectors feature low return loss values for 4K and 8K signals.

I’m not sure that the effects could be described as dramatic, but in my own experience, different BNC cables do make a difference to the sound and there are a couple of points that @Silvertone4 has made that do match with my own observations. Certainly, I think you can go too far with ferrites.

Some of you may recall that I tried out a few pairs of BNC cables - ranging from £750 to £4,000 a pair - when I first got my BluDave and there were differences between them that were quite easy to distinguish. Whilst the rankings were not entirely correlated with price, it was unfortunate that I definitely preferred the sound delivered by the most expensive cables. Fortunately, I found that adding ferrites to the cheap cables got me quite close and, in the end, I stuck with that. I said at the time that my preferred (expensive!) cables delivered degrees of subtlety and finesse that the cheap cables with ferrites couldn’t and, the longer I listened, the more this started to niggle. I discussed this last year by PM with Roy (Romaz) and we both were hearing the same things. He recommended a pair of Habst cables, but I didn’t pursue these because they were a braided design which I knew would probably be quite rigid physically and would not allow the easy addition of ferrites should I need to.

In September last year, I came across a review of the Clearer Audio digital cables which was intriguing and, given that CA allow 60 days trial and return, I had nothing to lose in ordering a pair. As soon as I put them into my setup, I knew that they were pretty good as they were an instant improvement. They weren’t perfect, but the designer told me that they needed a good run in before they would deliver their best. Sure enough, they did improve the longer I used them.

In case anyone is sceptical about digital cables improving with ‘burn in’ and saying that this is simply expectation bias - and I would have no problem with someone thinking that - these CA cables were causing regular drop outs in the signal when using inputs 3&4 on the Dave, something that all other cables that I have tried have done on inputs 3&4, but which was completely resolved by adding ferrites. (Inputs 1&2 have no drop outs, but I prefer to use 3&4 in order to maximise the distance between the BNC and the analogue out cables at the back of the Dave). The longer I used the CA cables, the longer the length of time between drop outs until the point where I no longer experience any drop outs whatsoever. I can’t explain that, but it is clearly not expectation bias. Also, I have no ferrites at all in the setup.

I did notice when Marc (@marcmccalmont) posted about the CA cables and was very enthusiastic about how they sat with his BluDave. I agree with that, but have avoided posting about it because I know that cables are a provocative subject and some people have become big ferrite fans. I’m sure we’ll start seeing people cryogenically freezing their ferrites before much longer.

Hi all

I've looked at the Blu2 manual but it only shows how to connect it to Dave.

How does Blu2 connect to the Hugo2? I'm looking at my Hugo2 and looking at a photo of the back of Blu2 and trying to work it out - so far unsuccessfully lol

Hi Malc. What Clearer Audio cables did you go for?

Hi Steve,

They are the Silver Line Optimus Reference 75 - 1m length.

 

[Jawed]

Certainly, I think you can go too far with ferrites.

The change in sound can definitely upset the balance of your system. The right thing to do is re-evaluate the rest of the system's setup.

It's impossible to go too far with ferrites on a digital interconnect. DAVE always sounds better with less distortion. That's what RF does: it adds distortion to DAVE's sound quality.

Hi Jawed,

I’ve had the cables for a few months now so I don’t feel a need to re-evaluate anything tbh. I appreciate your comments, but I’m not sure why you feel able to advise those of us running a BluDave setup that our system may be flawed when you do not own a Blu II yourself. Also, I’m running speakers whereas I think you are solely headphones, so there will be a number of differences in play because of that. What you hear in your own environment with Dave, a laptop and headphones may not be exactly the same for others and I’m not sure that you can accurately extrapolate that onto someone else’s BluDave speaker setup anyway. I know that you, like Triode Nick, are a strong advocate of not using expensive cables and try to dissuade others from unnecessary expenditure, which I consider an admirable trait in both of you and I am in favour of spending the least amount necessary to do the job myself as well.

Currently, I don’t use any ferrites at all and my system is sounding very good. I put the ferrites all over both of my USB cables when I got these CA BNC cables as you know, but I found that it compressed the signal somewhat so I have taken them all off again. Marc tells me that the CA cables do benefit slightly from some ferrites and he has very kindly offered to send me some surplus that he has which fit the CA cables - my ferrites are too small. I am very happy to try those out, but I don’t feel a strong need to at this point based upon sound quality. If they offer an improvement, I’ll certainly be happy to say so.

My approach has always been to go with what my ears tell me rather than be swayed by what other people think and say - and I won’t be changing that position ever because really, my opinion is the only one that matters to me. Comments from others, especially those you have come to trust, are helpful as a guide, but people should use their own ears and decide what is right for themselves.

Regards,

Malc

Malc has been to my house and heard my system. I think I have a good idea of what he is looking for in a system. He and I have arrived at similar sounds but from different directions and I am fairly sure we have a similar goal in mind when we audition kit. He is right that I try to spend as little as possible on cables and so far this has worked for everything apart from interconnects (but I have a theory about them which may bring them into the same category).

This matter of ferrites, no ferrites, some ferrites, which ferrites is interesting and I admit I have not quite got my head around if it is possible to have too many. In other words, can they do actual harm to the signal beyond a certain number or it is it just that a certain amount of distortion might be a preferred sound and that might be why some prefer fewer or no ferrites.

Today I have been trying out a new amp (PAss Labs XA30.8) and listened all morning using the Canare 12G-SDI/4K UHD 6ft BNC cables without any ferrites. The system sounds amazing. Sometimes it is better to listen to music rather than swop cables or ferrites.

Oh, and my theory about the interconnects was right and now I can sell my £2,000 interconnects and use my home brew versions instead.

By the way Malc, haven't I seen pictures on the CA website of cables with ferrites already installed as original equipment?

Very eloquently put.

 

[Jawed]

I appreciate your comments, but I’m not sure why you feel able to advise those of us running a BluDave setup that our system may be flawed when you do not own a Blu II yourself.

I know how RF affects the sound of DAVE. Blu or any other source isn't the topic at hand. It's solely the RF that gets into DAVE. RF always makes the sound of DAVE worse.

I'm puzzled why you think it's preferable to have some RF, rather than none, getting into DAVE.

"Too many ferrites" simply shows you that there's an aspect of another part of your system that you dislike.

Imagine Rob makes a new DAVE that's exactly the same sound quality but is entirely immune to RF noise from its electrical inputs. When you say you dislike the sound of too many ferrites you're effectively saying that this mythical new DAVE would also sound worse in your system...

Whaaat???

Absolutely right - in fact, since I’ve got my system sorted, I am far less bothered about what’s going on with all of these things. I used to come here quite a bit as I was refining and perfecting my system, but now I am simply doing exactly as you suggest.

It was very interesting hearing your system since the only thing we had in common was the BluDave - everything else was different. Not just very different speakers, but you were going into valve mono blocks via a preamp (passive pre, if I recall correctly) whereas I am going directly into a stereo SPM1200 MkII solid state power amp. You couldn’t get much more different in approaches, and yet my first comment when you fired it all up was that your system and mine sounded far more similar than different, which was not what I was expecting at all.

I am very interested to hear that you too have, albeit temporarily, arrive at a ferrite-less set up. A strange coincidence. I really didn’t like the weight, rigidity and lack of flexibility that they bring to the table.

Edit - yes, the CA cables appear to have one large ferrite at each end. I may have to take back what I said about running with no ferrites!

 

[Triode User]

I really didn’t like the weight, rigidity and lack of flexibility that they bring to the table

Assuming that you are being literal, I agree. I get fed up with the weight of the ferrites on the cables.
