The sound quality is good to very good. Offcourse every musician of Syngate has different producing techniques, but therefore again, the resulting output is pro-level.
The CDR's used are of the highest standard available. I believe they use Prodisc/Taiyo Yuden brands. They have a garanteed life-span of 100 years with a minimal of jitter.
Also the covers on the CDR's are printed because these special discs make that possible.
I know that Syngate makes use of the highest care they can.
