I had auditioned HTS3300 (same as 3400 except for AVR panel and added HDMI port) in Reliance Digital in an acoustically prepared room. Frankly, I was not impressed with the music performance. The satellites and sub were strained at just above moderate volumes, especially the sub was gasping. I had set the gain to 0db for all channels before testing. With Onkyo SR308, I switched to Polk RM6750 and wow what a difference. The powered sub was fantastic, I could feel the vibrations in my chest. Even at high volumes there was no distortion or fatiguing with the Polk. The satellites were almost twice as heavy as the onkyo speakers. For its price, its a good choice so I would suggest you to go with Onkyo 308/508 or Denon 1311/1611 with Polk package. Excellent VFM. Polk was priced at Rs. 19500 and SR308 was priced at Rs. 17500 (they were open for negotiation). ETC is ofcourse a better option but at a higher budget. Note that the AVR in HTS3300 (HT 380) does not have subwoofer preout, If I am not wrong; so think about future upgrades.
