Buy your receiver online. That one piece of advice I can't let slide past. I've never seen a reasonable price on any in store receiver. I've also never had any issues with receivers being shipped. A4less is a very reliable sales place I've never had any issues with them.
I'd suggest you get the Denon. They are reliable and have very short owners threads. Onkyo threads tend to be novels and Pioneer has skimped their amp sections in recent years. Just make sure you toss the manual in the trash and look up a man named Adam at audioholics. He's got manuals memorized and is a very helpful person.
Ares already mentioned that he's not into buying online, did you just read this very short thread?
Also, it is funny that you recommend Denon, and then mentioned Adam at Audioholics!
Because Adam is using the Pioneer Elite VSX-23TXH in his setup, and is very happy with it.
Also, you cannot judge a brand according to their novelty on some threads, can you really?
Finally, you mentioned Pioneer that have skip in their amp sections in recent years, but we are talking here about the Elite model, which is not in this situation.
And just one more, 'reliability'. I had Pioneer, Denon, Onkyo... since the 70's, and I can tell you that they are more or less reliable, depending on your use and maintenance. But they are all certainly reliable.
I had Denon units that brake down on me in the past. I have a Pioneer receiver since 1987, and still performing like if it was brand new. And I can say without a doubt, that when a component fails, it is not necessary a reliability problem. Many factors are in motion here.
The real truth is that nobody's perfect, they all have their pluses and minuses. The trick is to balance value, build, features, performance, and last but not least ergonomics.
I love my Denon AVR-3805, but I hate Denon manuals, remote controls, and inintuitive and complex menu setups. And that is a fact.
The funny thing is that you said similar things about the too much complexities in Denon receivers in the past, in particular referring to their Auto Room Correction setup: Audyssey MultEQ XT, no?
You like more the simplicity of EZ-Set from Harman Kardon receivers, no?
And here you go now recommending Denon!!! Are you for real?
Sorry man, but I just have to get the truth out here, for the benefit of Ares's (our OP) knowledge.
I'm not saying that the Denon AVR-2310CI is bad, because it is not, but you got to make a real honest distinction here, and according to the OP's preference.
And a lot of people are extremely happy with the Onkyo TX-SR707 as well. Hey, I own two Onkyo receivers myself.
Now, the Pioneer Elite VSX-21TXH, that one is a gorgeous looking receiver with strong build quality, and lots of very cool features, plus a great Auto Room correction, the Advanced MCACC that you can even fine tune manually, and with a Phase Control too. I just wish I can do that with my Onkyo receivers.
As much I love Audyssey MultEQ XT, I'm beginning to appreciate more and more the better sounding MCACC system with its much better versatility. The more I read about it, the more I love it.
So, Congratulations Ares with your excellent choice; you and your wife will absolutely love it. :T
Cheers,
Bob
