Speaker recommendation with Dev Expert 120 ($2000-3000)

[partita]

I'd say a pair of Gold Phantoms will be a better bet, that costs less than 120 alone.

I appreciate the suggested system. However I don't want to be restricted to an unupgradable system.

I see. How likely do you think you might buy a pair of high-end bookshelf speakers, such as Focal Diablo Utopia or even Magico Q1, in a few years? These are what I consider could make a big difference from all-in-one systems.

As a Gold Phantom user I'd say Beryllium tweeter is indeed a smart choice if you want a system that can outperform any Phantom, though.
