The vsx-1014 would be easier to setup, as it automatically adjusts the speaker levels for you using the included microphone. You place it at the typical listening position level in your room (like your couch), and the reciever will adjust everything for you. Since you don't have a spl meter, this helps level out your speakers much more accuaretly than using your ear.Power
Because of the room size, power from either of them should have enough headroom to listen at loud levels, so thats not really an issue. Sound quality wise, with the speakers you have it would be a tough time noticing major differences between the two recievers. The only difference you could notice would be comparing analog and digital inputs. The xr70 will most likely sound better than the 1014 with digital inputs, but the 1014 will sound better with analog inputs. How much better? Well, that depends on the speakers and the source. In your case, the difference is negligable. Both of these amps can bi-amp speakers, but not important in your case. Also, both of these recievers have a dual zone feature, in which you can listen to two different sources at the same time if you have speakers for front A and front B.Features
Feature wise, the 1014tx has the advantage of having the mcaac (Multichannel Acoustic Calibration), while the xr70 has hdmi input. Keep in mind that the xr70 accepts hdmi video/audio (hdmi 1.1) , but it can only output hdmi video (hdmi 1.0). Both of them feature component switching, and enough other inputs/outputs to cover the rest of your home entertainment system. The 1014 has 7 inputs, with a possible of 2 optical inputs and 2 coax inputs and optical out. The xr70 has 5 inputs, with a possible of 2 optical inputs, 2 coax inputs, hdmi input, and hdmi video out and optical out. Both feature an OSD (on screen display) on your tv.
The 1014 does have analog pre-outs for 7.1 output, the xr70 does not; although not very useful for your setup. The 1014tx has binding post type terminals for all speaker channels, the xr70 has it only for the front left/right A/B. This type of connection is more secure than spring clip type, and can handle larger gauge speaker wire.
For speaker size settings, the 1014tx has the advantage. The xr70 can only have the following speaker crossover settings: 100hz, 150, and 200. While there is a rolloff after the 100hz, its still not enough for most bookshelf speakers. Add to this fact that a subwoofer becomes localized above 80hz or so, and you can see the disadvantage of the limited number of settings. The 1014tx features the lowest setting as 80hz, maybe lower, but the manual doesn't state otherwise. This setting would better transition bass freq. from the sub to the bookshelf speakers. Of course you could always turn the crossover off, but your bookshelf speakers may distort more because of the low freq. bass.
For remotes, I would say the 1014tx has a better one. I've never used either remote, but from reading both user manuals and seeing what they look like, I would say the 1014's remote is more useful. The biggest reason is that the 1014tx has a learning remote, meaning that if your listed tv codes do not work, you can have the 1014's remote "learn" the commands from your tvs included remote. The xr70's remote just uses codes, if your tv isn't on the list, then you can't use xr70's remote to control tv functions.Overall
The xr70's strongpoints:
Digital input sound quality, hdmi input, size, weight, efficiency (hey, saves you something on electrical bill
) and maybe price.
The 1014tx's Strongpoints:
MCAAC, Learning Remote, Pre-outs, Binding post terminals for all speaker connections, 5 band equalizer, extended speaker Crossover settings.
In my mind the 1014tx is a much more complete home theater reciever than the xr70 and therefore would recommend the 1014tx over the xr70. HDMI will be a future standard, with revision 1.1 approved in may 2004. As far as I know, HDMI got approved for dvd-audio in 2004 as well. I would recommending the xr70 over the 1014tx if:
1.) You need/want hdmi input
2.) You're space constrained
3.) Most of your inputs are digital
4.) You listen to stereo recordings more than multichannel on digital inputs
5.) Hoping to add a dvd-audio player with hdmi out.
Hope this info helps, sorry about the long post
