I was seriously considering the 4310 vs. the 3310, especially because of the "name your own price" feature at 6th ave, which would have allowed me to purchase the 4310 for about 16% off MSRP.
Here are the main extra features, and why I decided I didn't need them (from your list in the other thread):
- 10 more watts
Even with my old receiver that had less power than the 3310 I could blow the roof off if I wanted to; more power wasn't really needed.
- 21367 x 2 32-bit Floating Point instead of x 1.
- MultEQ XT
It would have been really nice to have MultEQ XT, but I decided that the setup in my livingroom is pretty optimal in terms of where speakers are placed, and the benefits I would get from enhanced acoustic correction would be marginal at best (I also consider myself more of a videophile than an audiophile). I ran the MultEQ setup yesterday and it sounds great.
- Extra HDMI out
This was one of those features where I would use it if it was there, but if asked if I REALLY needed it, the answer is no. I don't run a LCD and a projector in the same room, so the extra output would have fed either the garage or the kitchen. I decided that if I ever wanted to take that route I would just use the Zone 2 output to drive them (even if it is just analog), or I would pick up one of these: HDMI splitter
- Front HDMI input
I don't have any portable devices that use HDMI. Even if I did, it's not that hard to reach behind the receiver to plug in a HDMI cord. The inputs are all along the top of the unit, easy to just feel your way around. Or you can get a HDMI port saver, leave it plugged into an extra port in the back, and just reach for it when you have to plug something in quick.
- AL24+ on all channels instead of just L+R. I'm not clear if this is of much value.
- Denon Link 4
- Some extra legacy ins/outs
- HDMI SACD support
- Stereo/Direct Modes w/Pure Analog Path
- Neural Surround Mode XMHD
- Direct iPod support via front USB port
I wouldn't use these features at all
- Wide Screen 7.1 Mode
- Audyssey DSX
A standard 7.1 setup is good enough for me right now. If it became more mainstream, then maybe I would think of upgrading to this. I decided to wait for the technology to mature a little bit before making the move.
When taking these decisions into account, along with a discounted preorder price on a 3310 (thanks santora), the extra cost was not worth it in my case. I was planning on upgrading my speaker set as well, so I decided that the money I saved on the 3310 vs the 4310 would go towards making a dent into that purchase. No regrets here.
