I received the Elac and they sound great in my living room and with the Audiolab.
It's clearly an upgrade compared to my Triangle Comete 902, and an upgrade that won't cost me 2000€... (so it's clearly a +)
Of course, they're not as good as the Evoke 20 but they are 4 times less expensive. And clearly (at least to me), the difference in sound quality is not worth 1,5k€.
So I'm going to keep the Elac and call it a day
Thanks to everyone for your advices. It clearly helped me !
If anyone reads this without knowing how to move forward in his choice, I would say the best advice I received here is to go in a store and listen, that will help you to decide. You will understand better what you're looking for, what you don't want, and after that, the only question is budget
thanks for the thread on eq for the living room. I'll have a look into it because it can me fun and useful !
