Hello everyone,
I naively didn't expect this thread to go on for so long - silly me
.
A number of posts ask questions about QED's design procedures and controls, which I'd like to clarify.
(1) Does QED undertake quality control in the far east?
Yes, QED conducts vigorous product testing and quality control on suppliers' premises and at our facility in Hong Kong. 'Armour Asia' (QED is an Armour Group Brand) was formed for precisely this purpose and we have a whole team of people whose sole job is to ensure our products meet our tightly controlled specifications.
(2) Does QED design/specify everything that goes into every one of our cables?
Well yes, of course we do. We specify precisely the number and diameter of each individual strand of cable and of course, the purity of the copper or silver involved. We also precisely specify type, size, density and construction of all the dielectrics and of course, the geometry of each cable. That is, how all the strands are bunched (or not), the 'twist rates' and how they are positioned within the various dielectrics.
How do we decide such things? Through lots of objective research and measurements at our facility in Woking, until we attain the results we wish to achieve. Naturally, these concentrate around the cable's Resistance, Inductance, Capacitance and Dissipation Factor.
(3) Do we undertake blind testing.
Again, yes of course we do. We conduct blind tests of our products against our competitors' models and also during the various prototype stages when developing new models.
Sometimes (but not too often) - Shock, Horror
- we discover that the sonic performance of one of our competitors' models has overtaken us. I confess that was the case about eighteen months ago and the new Reference Audio 40 and new Signature Audio 40 interconnects are our response to that discovery. We're very confident that we again lead the field.
Best regards,
