I created a separate thread for this, but found this dedicated thread and figured I might be better off posting here. This is my dilemma:
I have a home theater system built around a Pioneer SC-1222-K receiver. A friend of mine who is into much higher-end audio than me offered me (for free!) his Denon AVR-4810CI, which he recently replaced.
The Denon, I know, is a much higher-end receiver, originally retailing I think for around $3,000, whereas the Pioneer retailed for $1,100 and I bought from Newegg for around $600. The Denon is also a Class AB receiver, while the Pioneer is a Class D receiver. (My friend definitely prefers, as I think do most audiophiles, the big, heavy, Class AB approach.)
The Pioneer is currently driving JBL ES speakers (two ES80 towers, ES25C center, ES10 surrounds, and an ES250 sub). It has served me well, and has the right mix of modern features for my set-up, including built-in Airplay. I have a blu-ray player, Amazon Fire TV, Apple TV, and Xbox 360 connected to the system.
So here's my question --
The Denon would win most every comparison hands-down, I expect ... Audyssey MultiEQ vs. MCACC, 140 vs 110 watts per channel, 9.3 vs. 7.2 channel, etc. ... but ...
... I believe the Denon first came out in 2010, while the Pioneer came out in 2012. I know one feature I'll be missing is built-in Airplay (not a deal-killer, but nice for second room speakers; I've found that most receivers can't take audio from HDMI sources like the Apple TV for second room) ...
Any other issues that I should expect to see?
I'm a little hesitant to take my whole system apart, which is working well, only to run into some issue that I didn't anticipate when trying to sub in an older receiver. On the other hand, the Denon is a great piece of equipment and I think I'd probably be foolish to turn down the chance for such a substantial upgrade. (If I do go with the Denon, I will probably add a couple more ES10 speakers for front height channels.)
Any thoughts or advice greatly appreciated.
Just to be clear, there's no cost factored into this decision -- the receiver is being offered for free -- it's simply a question of time and convenience, weighing higher quality amplification vs. newer features. (Oh, I should probably add that I have no plans to go 3D or 4K with my system any time soon...)
