I'm tempted to take a punt on some Siemens and Halske cca for no other reason than I fancy seeing what this NOS mullarkey is all about.
They are first and foremost for use in my A/N DAC.
At current rates they're going for£80/£90/£100 on Ebay. Are they worth the effort and will they make a fair bit difference.I've missed out on a couple of pairs recently and its irritating me!
Is there anything I should watch out for/try to avoid. I'm only looking at those that are stated matched pair and can show readings and appear to be sold be reliable sources.
I'm using gold pin Electro Harmonix at the moment.
