Amarra a worthy investment?

Mikey - I use full Amarra EQ on all systems, even at shows, even on TAD reference speakers. Makes a big difference with ALL speakers. This is actually more important that EQ of the room resonances. Its like replacing your speakers with $50K speakers.

Here are some tips on how to do it with an iPad:

Thanks Steve, I'll get on this.

I have Amarra and the latest Audirvana+ with exclusive access and integer mode. In my system, with Mountain Lion, I find that Audirvana+ is a bit less colored, more transparent and offers a bigger window into the soundstage.

I'm using Amarra and Decibel. To be honest, I don't hear a lot of difference between them. Amarra has the interesting EQ functionality that's fun to play around with. I like the clean uncluttered interface of Decibel, so I seem to be using that more. Decibel is also a lot cheaper.
