Well I cant speak for Randy. But I find its always better to go with more power than less power, to secure you for future upgrades. Many enthusiast upgrade their speakers more often than their components unless they become faulty.

I agree with the poster that I quoted. I figured the more power the better. Emotiva told me since my speakers are so efficient that I am not using the amp to it's fullest and not driving it very hard. I guess my amp should last a long time....biggrin.gif

I did audition the XPA-5 with my gear before settling on the XPR. Normal volume levels between the two were fine but something was missing when I cranked the XPA-5 to 11. I'm betting that the noise floor is very similar between the two now since the XPA Gen 2 has the same gain as the XPR.

That's fine,I can understand why you got the XPR ...you have
Speakers that can handle that amp....or is it vice versa?
Just not following the 150 watt inwallls logic.

Understood....but he has some great inwallls,probably not gonna get upgraded
As often as you or I might. I'm not very familiar with inwallls, do they make units that
Can handle 400 watts of amplification?

The question I posed for Randy was why he picked the XPR over the XPA.
Both easily exceed the recommended continuous power for his inwallls.
And I would think that the current reserves of the XPA could even handle the
Instantaneous peaks that might be delivered to the speakers short term.

What am I missing here??

Well, you don't have to believe me. That's the great thing about having free will. Judging by your name you're either a fan of Emotiva or the stereotypes of people who dress in tight jeans and get "emotional" about everything. I'm guessing the former. If that's the case, you may want to search this forum. Someone here posted a response from one of the Emotiva engineers who stated that all properly designed amps sound the same. An amplifiers job is to amplify the signal. Nothing more, nothing less. Look at the frequency response of the Emotiva amps that they publish. The graphs on them are pretty much ruler flat. How does that equate to better sound if all amps provide the same response? The only difference between amps that might make audible differences would be THD and SNR. Again, all properly designed amps have those specs well below human hearing threshold.

As I said above, an amplifier's job is to amplify the incoming signal unmolested. Nothing more, nothing less. If it has a processor that does "more than just amplifying the sound" as you say, it is no longer just an amplifier. It is now a signal processor. I am talking about amplifiers not signal processors. All properly designed amplifiers will sound the same when not driven to clipping.

Sorry, I don't have golden ears like you so I'll be the first to admit that can't tell the difference between a 0.01dB in frequency deviation that Emotiva claims in their specs. That's probably why I don't pay $1000/ft for speaker wire either. The benefits are lost on these unrefined ears of mine. Also, I've only been an "Audio Aficionado" for the last three years or so. I don't have the experience you have in being able to hear things so you've got me beat there too. Same for car amps. I can't tell the difference between all the amps that have gone through my car either so I suppose I should dump my systems and start over with all Zapco amps that would cost me more than my car is worth.

That settles it, I'd better sell my Beyer and HiFiMAN headphones too since my ears now know that sound coming from headphones are different from sounds coming from other sources and will cause hearing loss. Now I need to figure out how two strap my speakers to my ears to avoid hearing loss from headphones.

Something we can agree on.

You are correct, I am uneducated. I am technically a high school dropout. At least I know the difference between your and you're and hi and high. wink.gif

No, capacitance and toroidal power supplies do not influence sound so long as they are not being driven to produce more power than they are rated for. No, amp class topology won't decide how clean and powerful the amplified signal is. They will dictate how efficiently the device will amplify the signal. How clean the output signal is is based on the amplifier design. How powerful the signal is is based on how much current and voltage the amplifier can produce. We're talking about properly designed amps here. So no, the noise floor will not be audible unless you like to listen to your equipment at full volume on super sensitive speakers with nothing playing. I for one, do not listen to my system that way. I like to actually play music through them. Like I said previously. You don't have to believe me. I'm just some uneducated person on the internet. Search this forum for the post I mentioned. It's here somewhere.

I'm not in denial of headphones causing hearing damage. I question that it's solely because they come from headphones. I'm pretty sure it's more due to the fact that people listen to headphones at volumes that are damaging and not because the are coming from headphones. I'm sure going to rock concerts would cause far more hearing damage than listening to headphones at 60dB for the same time period. BTW, sound does not need air to be able to travel properly or effectively. Sound actually propagates faster and farther in water.

No, I wouldn't because that would be unpleasant. That is neither here nor there since that is not what you originally said. You said (and I quote) "I have never listen to any music through a pair of headphones. Which science has proven does causes hear loss overtime." You are stating listening to music through headphones cause hearing damage. You made no mention of "blasting hi decibels".

Glad you love them. I'm sure the company you bought them from also love them for all the easy money they bring in. What I do love is how you like to preach science and going to take a class in science yet dismiss the very same science that proves speaker cables make no difference in SQ once they are of sufficient size to deliver the required current.

Sorry, too uneducated to develop a cable on my own. It's far easier and cost effective for me to order a bulk spool of 10AWG pure copper wire when they go on sale. It's also due to my poor education that I have absolutely no idea what "smdh" means. I do notice that you do seem to like closing your statements with that though.

Ok, I apologize to everyone on this thread and especially emofan21. I did reply and attack him or her and it was uncalled for. I blame it on this flu and the heavy meds I'm on for my short temper. I can barely keep my eyes open any more. If emofan21 wants me too, I'll delete my posts or edit it tomorrow once I'm more clear headed. The content, for the most part, I stand behind. The sarcasm, personal attacks and delivery was unwarrranted though. Again my apologies to all.

Can I use the Furman ADP-1520B Power Adapter with the XPR-5?

Here is a link on Amazon:

http://www.amazon.com/Furman-ADP-1520B-Power-Adapter-Black/dp/B0063R8OPC/ref=sr_1_1?ie=UTF8&qid=1395021252&sr=8-1&keywords=Furman+ADP-1520B


My theater room got a 15 amp wall outlet. Having someone come to my house and install a 20 amp in the theater room is NOT happening. They would have to rip my house apart redo all the wiring in the house. My wife would not take that very well and the cost as well.

On Amazon, there is a reviewer By Flytheater . The person seems to be very happy with the Furman ADP-1520B. Below are Flytheater's comments:

"My Emotiva XPR5 Amplifier requires a 20Amp circuit/wall plug. This is a great adapter to convert amplifier's cable to a 15Amp wall plug. I recommend this item for those who don't have a dedicated 20AMP plug for high power audio gear."
