The avr would shut down on thermal protection if I listened to more than one song at 78 absolute volume setting in 5 channel stereo.
This is weird, Shorted speaker wire(s)?
What sorts of SPL are you going for during your listening sessions?
Have you calibrated your AVR with Audyssey? If not, your volume control settings mean nothing.
then sold it for a more powerful unit with the hope of getting louder and not shutting down.
No hope of that working.
I got the Denon 3313ci for Spotify, extra wattage, and hopefully longer playing time before shutdown. To my surprise, going from 75 to 125 Watts was hardly noticeable volume wise.
As others have pointed out, thats worth a couple of dB on the best day of your life, and presuming you are already gutting your system out with the volume control.
To top it off, I maybe got only another minute or so of play time before shut down.
How long were you letting your system "warm up" before you do these tests with immediate shut downs?
I think I got the heat situation a little more under control by hooking two PC fans up to the 12v triggers.
So there was a heat problem?
Ultimately, I returned the receiver because I did not get the improvements I expected as far as heat or power.
If you'd asked...
Now that you know the situation, this is where I need help. I am considering a few options: avr x2000, 3313ci or x4000 (i know the differences between both) with Emotiva xpa5, or 4520ci. My reasoning for those avr's are as follows. I am considering the x2000 because it has all of the features I want including amped zone 2, it is the cheapest option, and since the power from 75 to 125 watts was barely noticeable, I assume going back down 25w will not be audible. Is that right?
If 50 watts more didn't do much for you in a positive way, then 25 watts less won't do much for you in a negative way.
The 3313ci or x4000 with emotiva xpa5 route will give me the power I would like to have. One thing I was wondering (never had a home audio amp before) is if I will be able to control the system volume with Denon's phone app. Does the volume have to be changed on the emotiva
I keep telling people to actually spend a little time checking these products out for at least 10 seconds before they start thinking about buying them. If you look at http://shop.emotiva.com/products/xpa-5
for a few seconds you will see that it has no volume controls.
or can I just leave it turned up and control the preout volume with the remote app and Denon remote?
The AVR volume control is what controls the preamp, as well as the amp outs.
I am not willing to give up the ability to control the volume with the phone for the amp.
Lastly, if I cannot control the volume with the app while using an amp, I would consider a 4520ci for its 150 watt amplifier. Would I notice the increase in power/ volume from the 95w x2000 or would I be spending the extra $ and not get an audible power difference.
Well we know what you think of 2 dB increase (not a heck of a lot and properly so) so we kinda know what you will think of a 3 dB increase. Not a heck of a lot.
Ultimately, if I will notice a power difference going from Denon's 95 wpc to Emotiva's 200 wpc and can still use the remote app I will do that. If I cannot use remote app will I notice a power difference from x2000 95wpc to 4520ci 150 wpc? If the answer to these is no, I will just stick with the x2000.
95 to 200 watts is the same mild 3 dB increase as the one from 75 to 150 watts. If you want twice as loud you want 10 times the power, and that would mean buying new speakers as well.
I hope you knowledgeable folks can take the time to help me with this. I am getting sick of pondering it.
You are describing something very atypical.
Unless you are deaf, what you have should be pretty loud. Your story about 2 different AVRs tripping out after a very short periods of time is not the symptom of a AVR with too low power, it is a story of a system with short(s) in its wiring or short(s) in its speakers which can happen if you have a rubbing voice coil in a woofer, for example.
And +1 to what 67Jason said. Don't churn any more equipment until you get your current situation cured.
