I'm a complete newbie to the amplifiers though and my questions are the following:
1. Will powering my speakers through the Emotiva XPA Get3 (most likely 5 channel or hopefully 7
) improve the sound quality dramatically or will be barely noticeable? I used to power my JBL Northridge E90 floor standing speakers with the E30 center and Studio L830 surrounds. The sound was very good. Now, I will be powering JBL Studio L820, LC2, and L810 for the space reasons that used to run off Onkyo HT-RC160 in another room. I guess the real question here is whether or not TX-NR3009 truly delivers the promised power as per the specs or there's room for growth.
2. When using the amplifier, I assume you control the volume on the amp and not the receiver anymore. When people use multiple stereo amps, do you control the volume of fronts, center, and surrounds independently on different amps? Sorry if this question sounds silly but I really have 0 experience with pre/pro and amps. Only AVR experience...
Thanks in advance,
First things first. You will still use your AVR just as you always have. Volume is controlled by the AVR and the output (pre-outs) go to your amp(s).
As far as a noticeable difference, you have to ask yourself the serious questions. Do I listen to movies/music at high volumes? Do I hear any sound anomalies coming from my speakers when I push them hard?
If you listen loud, you might very well get better response from your speakers. They won't sound any different, you will just have headroom to play with for demanding content. At moderate volume levels, you won't notice any difference at all.
With a recommended amp rating of 225W for the E90s, you would be in the "sweet spot" with 200WPC. 250WPC would be about as much as you could ever need.
As far as the NR3009 delivering the rated power... yes it does, but only in stereo mode. When you add channels, you drop the power. If you are running 5.1 you will probably have around 80W - 100W per channel. Less for very demanding content like bass-fest movies.
I own the 3009 and have the XPA-3 powering my RTiA9 speakers while the AVR powers the center and surrounds. I get some seriously powerful sound from the system with the amp. It's clearer and heavier on the bass during bass intense scenes too. I have all my speakers crossed at 80 Hz, which helps with the power, and am running two 15" subs for bass material. It is truly visceral and blissful.
Your first though should be with a powerful, dedicated subwoofer. That will make your system sound better right off and you'll think you have a whole new set of speakers. After you employ a good sub, then you should look into the amp for the mains. Good luck and good listening.
