Driver specs, designations, materials, weight, size, etc all help us to come up with theories. But the bottom line is they all mean shit.
I don't doubt the new S3's will be wonderful speakers. But saying they will be better or worse than the S5's seems crazy to me when none of us has heard them.
Proof is in the listening, not speculation.
I'm not trying to negate the excitement over these new speakers from Magico, I'm ultra excited. But we all need to relax until we hear them. Predictions, bring them on. That's half the fun, but remember they are only predictions.
