I am looking on opinions with for the following. I currently have a Yamaha RX-V2095. I have recently purchased an RX-V2400 that's on it's way for $700 for a friend of mine, but he doesn't need all the features and is willing to give me $450-$500 for my old RX-V2095. So, it'd be like spending $200 to go to the RX-V2400. I do like Yamaha processing, etc. The 2400 has all the new DD EX, DTS ES, THX, etc., excellent bass management, and utilizes newer 24-bit DAC's than the 2095's 20-bit ones.
The only thing I'm concerned about is the amplifier quality. I've never heard the 2400 in action. The 2400 is rated at 120wpc vs. the 2095's 100wpc. But the 2095 is rated at 0.02% THD with a damping ratio of 200, while the 2400 is rated at less than 0.04% THD with 150 DR. I'm really not sure how that'd affect the sound.
Good news is that I'm planning to purchase an external quality amp in a few months, so the 2400 would be used as a processor/pre-amp. I'll be using the B&W CDM series speakers, so would there be much difference in using the 2400 or the 2095 in sound quality, if anyone's familiar with both receivers.

Thanks!
