Mark7767 ; I have a smaller room so I have the ML#383 driving B&W 803N's. I have found Cardas Golden Reference to be just fantastic. A perfect match by not only my ears but several friends that know my system. One is a reviewer that loaned me Nordost Valhallas for 2 weeks. I could not justify the price difference, but for what it's worth I prefered the Cardas. I'm not saying one is better than the other, it's just what I prefered. Peace and Good Listening, Pat.
