What were the Denon's paired with ?
When you are spending close to a Lac rupees, then it should really should be a stand-out performance... I would suggest you to consider Denon X4000 over X2100 (or) X 3100...
Since it is an year old model, you should get a good discounted price....Alternatively you may consider the above said Onkyo models & Marantz SR 7008....
All the suggested models have Audyssey Multi EQ XT32 which is one of the best Digital room correction aval in the market....
The Denons were paired with Polks, same as mine. The newer Denon models are with Bluetooth as well as wifi, so that's an added benefit. The x3100w is priced at 110000 and the x4100w is priced at 150000.
The newer ones are with a little better video and audio processing technologies.
