Use your ears.
If you're smart, take a look under the hood and see what and HOW it is made... the best consoles I've worked on or owned ended up being "worked" on over the years... infer as you will (and what that means in console "build" to do).
Funny how everyone seems to need to proclaim a winner, when by my estimation, back when there was a blind test on the Ciozzi thread, by around post #69 or so, the consensus was, "Eh, personal taste, can't tell the difference enough to say which is really which."
So, back to basics...
1. Use YOUR ears.
2. See what and how the console is made of.
3. Know what YOU want and what you NEED.
The best these forums can do is provide SOME info and user insight, the rest is entertainment.
