This is an interesting discussion, as I am pretty much in the same situation; planning my upgrade.
To provide some background, I am based in the Philippines, so availability and pricing is vastly different from the US. I am in communication with various retailers, and will post an update with prices once I receive them.
I currently have a Yamaha RX-V375 5.1 channel amp, and am looking to move to a 9.2 channel amp. I was trying to decide between 7.2.2, and 5.2.4, and am now leaning towards 5.2.4. Do share your thoughts if you believe 7.2.2 would be better.
My front towers are Polk Audio Signature S50's. Picked them up last year, and am very happy with them for 2 channel stereo. My upgrade now is purely for movies and home-theater. That said, if there is more quality to be extracted for stereo music listening through this upgrade, great!
The contenders:
- Denon AVR-X3600H
- Denon AVR-X4500
- Marantz SR6013
- Marantz SR6014
- Onkyo TX-RZ740
- Yamaha RX-A2080
The Onkyo is the cheapest of the lot.
What I've read so far:
- The 6014 has little in terms of new features, making the 6013 the better option.
- The Marantz can run really hot, which is a bit of a concern, given the already hot tropical climate. Though the receiver will be placed in the open.
- Marantz receivers are great in terms of their musicality, and should be the first choice for stereo music.
- I do prefer the larger screens, with more info displayed, especially the speakers in use, and the movie soundtrack format being decoded (DTS, DTS-H, Dolby Digital, etc.). This puts the Marantz at a disadvantage given its minimalistic screen.
Let me know of your expert thoughts and suggestions please.
