I have the Audio technology 7" (Auto ver) together with Scan Speak D3004/602000, CDT 6x9, Audio Technology 10" sub, all active with bit one and McIntosh amps.
Lately I bought of a friend a set of DynAudio Esotar 2 3-way + 12" Esotar 2 subwoofer.
What do you think? Should I replace my system or not?

 

Yes. In two independant reviews I have read the Esostar came out on top with Scan Speak second. The midrange test had 16 sets and the midbass had 11 sets so to be first and second in both is no mean feat. Both are an excellent range of speakers. If it was me I would be itching to install the Esostar just to find out which I preferred.

 

Do you have a link to those reviews?
I also have to choose between the Esotar 12" (1.5 cubic ft needed!) and the AT 10".
