All of the Phantoms are the same size and weight. The only difference is the electronics inside. The Gold does have a titanium tweeter. Devialet massively over engineers their products. The ADH2 upgrade is software. I received my upgrade to my Silver Phantoms about a week ago. Then I noticed a difference in sound. The bass is now much cleaner. It sounds more like a Gold. I do not think ADH2 increased the power of the Silvers. But I think they made more of it available. The software appears to better optimize the power supply. I think that is why Devialet offered the Gold upgrade. They knew the Silver would be much better after the upgrade. The differences are subtle, but some songs that sounded harsh when you pushed the volume is now much more refined as you get louder. Before, going from 50-60 was a dramatic increase in sound and harshness. Now the entire range of volume is smooth. NICE! It is like getting a new pair of speakers for free.
