I think we as Meridian owners are missing out on hi-rez, as I think with high quality recordings, it makes a difference. However, I think SACD is not the tool to use. Meridian isn't the only person who questions the quality and virtues of SACD. The founder of Ayre is also on the non SACD camp, as are most in the recording industry.

What is the deal with Pono? Are we to assume a Meridian portable hi-rez player is in the works?

Upgrading Meridian to high rez would be one hell of an effort! You would need a hardware upgrade for almost everything they make?
