Mothra regarding "different league" depends on the context and how it is used.
In my thread, I gave my experience of listening to two different systems, one being superior over the other.
If you heard a system that was great but then heard another system with the same music listening to both male and female voices and one left you in awe what would you call it?
You listen to a variety of music including all kinds of musical instrumentals including the piano and one system is alright but the other is just more realistic what would you call it?
You then listen to pieces that show off stage presence, pieces included such as Phantom of the Opera, Oliver, My Favorite Year and the stage presence was just so unbelievable scary real what would you call it?
When you put on other music like Tchaikovsky 1812 and when the canon shots go off they startle you like it was the first time you ever heard it. You then put on Dafos and Kodo Drums and it's all so real sounding what would you call it?
Ending the evaluation listening to Fiesta! Dallas Wind Symphony "Prelude and Axtec Dance" and there is just no comparison then what would you call it.
I call it in "another league"
