I also had the da9 and now I own two Sabaj A8. Perhaps because my speakers have low sensitivity and require many watts but I find the presentation of the Sabaj sound is infinitely better.
in the end could you give us a final judgment on the sound quality of this amplifier? I think you could post this review on the forum because I find it very professional I think Amir would promote it among the approved reviews!
