Amarra a worthy investment?

Audioengr, new to the thread but I am glad I read your post. Would have saved me a lot of money If I read it earlier. I did as suggested in the link you provided. Downloaded the audio tools app in conjunction with the Amarra eq and I am astounded at the improvement it has made to my system. I hear absolutely no negatives by using the Amarra eq. Like someone took a blanket off my speakers. Rock music always sounded muddy and distant. Now it is tight, detailed, and clear. I had some big dips show up in the response of the spectral analyzer and smoothed them out quite a bit with the eq. I thought my system sounded pretty good before but now when I toggle the eq off and on I don't see how I ever listened to it before. My wife listened to the before and after and she couldn't believe the improvement. I actually liked Audirvana a little better before but now Amarra will be my go to player and the eq will stay on. I think if I play with it some more I can get it even better.
