+1 on Dynaudio. Love your own!
Pero kanya kanya pa ding preference yan pagdating sa tunog.
Basta dapat adequately powered yung speakers para dynamic sounding and walang compression.
In my opinion, for HT application, malaking factor din yung receiver dahil iba iba ang ginagamit na EQ. For example, Denon, Marantz, NAD and Onkyo use Audyssey (not sure if they all have the same target curve though). Pioneer and Yamaha use their own proprietary calibration softwares. So this means that the post-calibration output of your speakers is usually going to be very different from their original sound and will be highly dependent on the target curve/response of your receiver's EQ software.
So my theory is that by using the same receiver (with a high resolution filter like Audyssey Multi EQ XT / XT32) to drive two different brands of speakers of the same class in the same room, I think more or less the resulting sound after calibration will be quite similar. Pero kung walang EQ, definitely magkaibang-magkaiba yan.
Sa 2-channel audio naman usually hindi ginagamitan ng EQ kaya mas crucial yung synergy ng whole system including the room.
Mas okay talaga kung hiwalay ang audio and HT para walang compromise pero tiyak na mas magastos yan! hehe Pero pwede rin naman pagsabayin sa isang room ang HT and audio with very good results just like sa system nila sir Streetsmart and Nelson de Leon.
