I think there is at least 3 diferent HW versions, the first with LM1950T ( i have this ), the second with CS8240, and the third with LM3526H.... i cant say which is better as i only have 1....
If you dont have the skill to do the tests posted, then better contact reseller, or Mr. Cyclonebox ( see this post )
