New Acoustic Zen Matrix vs. old Matrix


Has anyone heard the newer versions of the Matrix and Silver Matrix?? There doesn't seem to be any info on the website about newer versions. Thanks.

I emailed Acoustic Zen with the same question about the Silver Reference, and this is the response I got from David Schiavone:

"The newer version has a little less harshness in the lower tremble.Where they also differ is the new version has a fuller low-mid bass.These are the two areas where the new version excels."
