Old thread. If anyone prefers the sound of the Harbeth and desires to have a slightly more transparent, open and detailed sound, the Graham is a good choice. Basically a sound with slightly improved clarity and detail which can make a significant difference to the listening experience. My comment is based on the comparison between the equivalent Graham models to the older Harbeth pre XD models such as P3ESR, C7ES3, M30.1 / 30.2, SHL5+ and M40.1 or 40.2.
I've listened to the Wilson Sasha mk1 about 11 years ago. Sound is rather good.
