That is why I bought my SD9, which will soon be in tgx78's hand. The GD5 looks like it's very well tuned as well.
Edit: replied to the wrong post, but we will have tgx78's graph of my SD9. Meant to reply to #979. Same same.
I just got home and measured @Rush87 's SD9. I will listen to it tomorrow as my hearing is very tired from work today.
