George!
How I can tell you!?
Next upgrade will be probably the acquisition and the moving of Victoria Hall near your house to have the best acoustic for your listening experience.
You know what's the worst thing og this thread? I was thinking I'm spending too much trying to have a full DSP 7.1 system and I was almost convinced about this.
Now, I'm back to reality and I undestand that probably I'm not even understanding the real dimension of the financial hole I'm going to do in my pocket in the next years buying M stuff.
The good thing is that when I'll be able to afford a pair of 8K the price will be lower because the 10k and 12k will be here.
