Where have you seen the Cinema 50 measured?One thing I am confused by is that the X3800H was reviewed poorly on ASR, but the Marantz 50 measurements were praised by everyone.
Do people generally like the X3800H sound?
Amir's comments on the 3800 have to be taken with a grain of salt. He was disappointed that the SINAD regressed from the prior 3700 (which was excellent and running AKM DACs at the time). However, the absolute SINAD rating of the 3800 still falls in the "inaudible" range! I've had my 3800 for nearly a year and along with Dirac Live, it's the best setup I've had in some time!
Just get the 3800 and wait for Black Friday/Boxing Day for Dirac's annual 30% discount on licenses!
