there is actually noticeable difference even with less expensive Master series for Utopia compared to the standard one. Silver clearly gives more air to teh soundstage. So it might be matter of setup or simply subjective. Since everyone has it's own opinion, it's totally normal. Some guys might even use their iphones with $500+ custom 28 core cable for HE1k as we just experienced and then later pretend that there is totally no audible difference, others might have decent setups and otehr impressions like here, for instance.
no, we dont use cheap terminations, besides we offer different options and also some not listed on request.
I agree with the first part but not with the second one : "no cheap terminaisons". Everyone can check the retail price from an anonymous buyer of :
- ViaBlue 6.3mm : around $15
- Neutrick NC4MXBB : not found on my price list : NC4MX-B should be around $3.75 NC4MX-HD should be $9.20
Leaving in France, I can't borrow a cable and send it back with restocking fees (I've just noticed that you have no rstocking fees for standard 2m cables which is great). That's why I have to rely on others' opinion.
I tried to understand :
I think what matters the most with terminaisons is the way they are implemented. One can use very expensive ones but I think it will add a few drops for a lot of money. So your's could very well do the job.
I was surprised that no sound difference was found between the stock cable and your silver cable. Your's could be worse (I don't think so for the Grand 20 but some could find it "too bright") or better (which is what I'd had bet on, at least for the sounstage) but definitely, there should be a hudge difference between OFC and 6N silver cable.
So I would advise anyone living in the US to give a chance to your GRAND cable (I wouldn't recommend the Master line for those high-end headphones) as they only risk to be more than pleasantly surprised. Lucky guys.
My only wonder is the lack of outer jacket which could protect the silver cable itself.
May be you should allow a 4 weeks return period for the GRAND line as those cables needs at least 150 hours of breaking, which is 6 days being continuously used.
This is just my humble PERSONNAL opinion (not the truth), based on my little experience looking for cables, knowing we have all a different major equipment : our hears.
