I am looking to upgrade my current HT package consisting of DefTech 7002 (fronts), DefTech 2300 (center), DefTech 7006 (Rear) and DefTech 2002 (rear center) driven by a Denon 2807 receiver. I wish to go the separates way and want to get your expert opinion on the best pre-amp, amp combo available in India (would welcome good domestic manufacturers too) to drive these speakers. The fronts and rear are rated at 92 DB, 8 ohms. Their frequency response is 15Hz - 30 KHz (they have built in subwoofers). The centers are rated at 91 DB, 8 ohms. Hope this much info is sufficient for a recommendation. I use them for movies and music 50-50.
