Cardas Neutral Ref vs Harmonic Tech Pro 9 Plus

Was wondering if anyone out there has owned both of these cables and if so which was the preference & why. Music playback consists of Ayre K-3x preamp to Threshold T-200 to Aerial 10T speakers. Same setup for HT through the Cal 2500 SSP. All current interconnects are Cardas golden cross. Any and all feedback appreciated as well as any suggestions for future considerations....need 10 foot minimum and used price target of less than $1,500.

Thanks
