I was glad I had, because with the files anonymised and level-matched, the differences between them appeared vastly more subtle, especially with the capacitor microphones. So much so, in fact, that many of us in the SOS office felt unable to confidently tell the anonymised files apart in any repeated or reliable fashion. I will leave it up to readers to see whether you can do better — and to form your own opinions as to whether high-end preamps represent money well spent! Surf to /sos/oct12/articles/preampsmedia.htm to download the files and listen to them.
