Dracule1,
Dr. Diamond's friend was impressed with the detail of the Apollo's, but had some RFI issues due to his proximity to a radio station (as I recall). The Quattrofil's are Nordost's reference level shielded interconnect, and are a great cable.
If you would like to know more about the Apollo's, feel free to send us an email! (sales@silentaudio.com)
