It is worth every dollar(600$ may be tough price).
But I got some nasty bright treble sound sometimes.
I guessed that it may be due to the reflection from the windows on the opposite side of speakers.
I ordered some acoustic panels but in the meantime I put some chairs behind my listening chair and put monkey and rabbit on the chairs.
It worked with less bright treble sound!
