I’m actually OK with the Music RCA version price.
The equivalent Siltech is priced a bit higher, I’m demoing the previous (no longer available) version of that - the Siltech Crown Princess. It’s replacement is the Siltech Ruby Crown.
What I’m not OK with is the ChordMusic XLR version and the extra £2,000 that they want for it over the RCA version.
Now THAT is insane, luckily the DAVE sounds marginally better via RCA outputs anyway.
Chord Music is clearly better but at twice the price it’s not twice as good.
I suppose it depends upon how good your system is, and how deep your pockets are.
Sarum T is clearly wins with value for money when compared solely with Music, and Sarum T is a nice performer which doesn’t do anything wrong to point a finger at.
It’s just that Music cables are even nicer but ridiculous expensive 
I’ve learned that in this hobby, the rule of diminishing returns does apply. It’s not only with cables but other hifi gear as well. I have something that costs up to five times more but it surely doesn’t sound five times better.
It was suggested to me that in general you have spend three times as much on a replacement component to get a significant upgrade in SQ
What do others experience ?
I don’t disagree with you Debs, in fact we’ve shared similar/same views for years 
.
I absolutely 100% rate Sarum T and, on a VFM basis, would say it’s something of a sweet spot in comparison to others. I still have one on my 552 and most of mains leads are Sarum Ts, too.
Music isn’t twice as good - we’re all pretty much at that stage where nothing added can be 100% better - but it’s a sufficiently big upgrade to make nutters like me spend the extra and never regret it for an instant. If it’s at the expense of a child’s education or a once in a lifetime holiday, then no, don’t do it, but if you’re fortunate to have the funds available, I’d say yes, it’s worth it.
How can you compare with the quality is twice as good or not, it has no weight to measure, if it is better that`s the point to justify ,at the end it is a personal decision
Exactly that, Meni
You’d think that alone would be enough to put people off buying them, but the price is a close second! The Burndys are some of the most expensive in Chord’s range and that is saying something!
There are some Music speaker cables on the bay at the moment I have my eye on. I am sure they will go for a much more than the current price but interesting to watch them!
There is a need to express some degree of measurement to any given improvement, hopefully floating about between the adjective polarisation of rubbish or awesome.
A component upgrade with a subjective estimation of 25% audio improvement is very different from an estimation of around 100% audio improvement.
This involves the law of diminishing returns, and it’s this and the size of ones bank balance that should decide personal decisions of expenditure.
My only disfavour with Chord Cables is the pricing strategy of doubling with each upgrade so the price increases by 100% exactly. (although the audio improvement is considerably less).
It creates a difficult to justify a 1.2m cable costing £5k even if it does bring about an obvious and notable subjective estimated audio improvement of around 25%.
How does one measure, even subjectively, SQ improvement as % I am not so sure, but I have forgotten how much my Music speaker cables cost, and don’t want to remember - surely, what you mention here above looks wrong! 
Just looked those up, there’s also an RCA-Din interconnect, a Din-XLR and a mains cable - everything you need
There are different listeners, each of them will think differently, therefore it is not possible to give an answer in percentages, for one it is 25% and for another it is 100%
In which case it then becomes possible when two people give percentages, even if these figures are subjective opinions that are miles apart.
There is a need to quantify a given size of improvement in consideration to cost.
All I know there is 0.000000000000000001 % chance that I get those cables in my use.
Buy more music 
because you´re listening to music, not to cables 
Lovely nostalgia, but today you can listen to more and better sounding music without buying and accumulating more plastic
Wrong…you don’t need to buy CDs anymore and better cables will give you more pleasure to listen
The point is if you want to get the best sound in your system you don’t bother yourself with your bank acount
Funny. I´d like to focus on what´s worth to focus on.
In this respect, I am happy to repeat listen to music and not to cables again, because this hint and approach is not wrong: It´s just a different one, and with cable sound not really improving technical quality of a music reproduction but is driven by effects which are keen parameters to psychoacoustics, it is also the much more realistic perspective.
If you no longer know why you are doing something, then something is wrong. Negating music and putting cables in the foreground is one such situation
