Sabai, thank you for the info, did you compare Hidiamonds with higher models of Synergistic research? Robert does not provide with audition (at least this is what he told me) so the only way to find out about them is to ask people who heard them and compared them with other reputable brands and provide with details about comparison and their system. I know it is not enough, but better than statments like the best cables I have ever had in my system. So if possible please provide more details about what exactly did you buy (diamonds 7,8,9) and did you compare you cables with and what is your system consist of. This will help a lot to me and I am sure to many others who interested in Hidiamond cables. Thank you!
