A contender I'll add to my short list is the Dynaudio Heritage Special as one of the local dealer has a pair so I'll be able to compare them to 805 D4 and Elemental Fire V2. However, no luck to find a dealer to have the Sopra #1 on demo yet, and they are a bit over budget (11.5k CAD). If I can listen to them, I might be able to break the bank.
Thanks everyone for your advices and suggestions.
And don't miss the next part of this journey, the best song to evaluate a system (it will be speakers in my case):
