Hi all I just purchased and installed a XPA5 to power a pair of goldenear triton one speakers. I was using a new Yamaha rx 1040 wit a rated power of 110w.
It seems now I have to turn up the volume slightly more now than I did before. Like for example on one particular song it sound very loud at - 20db but now I get the same volume at maybe - 17db to get the same feeling. I honestly thought it would make the volume louder if anything? What are your experiences with with you xpa 5 replacing an old receiver?

The yahama must have a higher gain than the emotiva. I didn't find the gain value for the yamaha, but all the gen2 emotiva amplifiers have 29db gain. But don't worry the xpa-5 is still more powerfull than the yamaha rx a1040.

Often an AVR will supply less voltage from the pre amp outputs than it does internally. It's the reason why the Gen 1 power amps were designed with 31 db gain while Gen 2's have the more common 29 db. Using a higher volume setting on an AVR when using an external power amp is not unusual, nor is it an issue, it's just a number, forget about it and enjoy the XPA-5, I sure do.
Happy New Year Gary

So I am assuming that I will get cleaner sound out of my speakers with the xpa5 at higher volumes than my Yamaha could ever drive?
Since I have this power now could I turn my speakers up a lot louder with less chance of blowing the speaker do you think?

Most (but not all) speaker damage occurs as a result of the amplifier clipping, exceeding its volume capability and outputting uncontrolled distortion. The XPA-5 has a much higher output capability (before clipping), so that cause of speaker damage is far less likely.

Just turn up the level trims on your Yamaha if this bothers you.

Correct: the number differs depending on the gain stage of the speaker. So for 17 volume, amp A will put out 25 watts, and amp B put out 40 watts. However.... Amp A may have a maximum of 200 watts power capability. Amp B may only have a maximum of 50 watts. Amp A will get louder and play cleaner - despite it requiring a higher "number" on the volume dial. So basically, having to turn the volume up more has nothing to do with how powerful an amp can get. However, the volume knob (your pre-amp) wll eventually have a maximum volume IT can put out. Sometimes a very powerful amplifier, will make the volume knob (pre-amp) max out on volume before the maximum power of the amp is reached. As long as your pre-amp is ot at MAXIMUM volume and you are satisfied with the volume then you are okay. Now if it gets to just one step short of maximum to get the maximum loudness you want, then that's okay too The only issue is if your volume knob is at absolute maximum and it still isn't loud enough.
