Reference 3a Grand veena or Duntech Sovereign

I have a pair of Grand veena now and have been offered a used pair of Duntech Sovereign at very reasonable price. I read many other reviews and found that its soundstage is superb and I also listen to them once at my friend's home who use its as main speaker for home theater system and it is amazing!) My room is very large about 20x40x8.5 ft and used for both HT and 2 channel listening because I do not have another room for seperate system. I'm impress with the sound of grand veena as well but due to space I cannot keep them both if I decide to replace the Sovereign in my room. One more thing I use ASR Emitter II exclusive integrated amplifier in my system. So I want your opinions and suggestions about how these two compared to each other and whether I should keep Grand veena or get legendary Duntech.
Please recommend me to support the decision.
