I have a pair of definitive technology mythos st towers. They are running off a Onkyo avr which provides them with approx 50 watts. When I go past 82 (thx reference volume) it starts to distort pretty badly. If I were to provide these speakers a amp, something 350watts (their peak) or higher, would this eliminate the distortion at the higher levels and would this provide higher volumes?

I doubt that you need 350wpc to avoid distortion - but yes - an external amp might be worth while. Which Onkyo do you have? It might not have preamp jacks.

You sure have come to the right place!
YOU NEED A DECENT AMP!!!
And you simply can't beat Emotiva when it comes to beefy class AB power at decent prices!
I second the suggestions from deltadube!

You are in danger of destroying your speakers by under powering them. Massive amounts of good clean power will not do the damage that driving them with too little dirty power will do.
delta dune is correct! The MONOBLOCKS are a great way to go. Please post all of your gear so that we may be of better assistance to you.
Also the size of your room, listening preferences and treatments if any. Also, what and how much is your listening pleasure. % of HT verses 2channel or even 5.1 channel music?
The more you can tell us about your gear and listening habits the more we can help you in the wonderful world of audio nirvana.

Another recommendation for the XPA-2 from a previous Onkyo AVR user.

have a 1200 cubic foot room. 7.1 Def tech mythos lcr, some Ok surrounds. Subs are the towers, a Hsu vtf 15h and am building 2 horn subs. no treatments as of yet. I listen at high volumes very regularly, usually 2 channel music, 7.1 movies.

Steven, after reading your last post, I believe that you have little to no interest in a balanced system and that your priority is high volume 2 channel and great HT.
Therefore, I will agree with geebo, for a higher volume level and best value would have to be the XPA-2. Gust .02 cents more my friend.
To fellow members of the MONOBLOCKS Society, monos are Not always the answer,,,,,,,,,,,,Shhhhhhhhh!!!!!!!! Don't tell the Executive Board about my statement,,,,,he,,,,,he,,,,,

Do your Mythos towers have the powered sub? If so how are they hooked up? If they do have the powered subs, you could connect the Onkyo sub out to the towers LFE input and set your HP filter on the front channels. This way you could relieve some of the stress on the Onkyo amps. Are you getting the distortion in 2 channel or during surround sound use? Any particular source or all sources? The specs I could find on the Mythos are 93 db and the two channel power on the Onkyo is 100 wpc 2 channels driven. Pretty efficient speakers with an ok amount of power. I would make sure there is not something else wrong before jumping on to new amps. Though there is nothing wrong with buying new toys just for the sake of it  |

I Sorry, I mean no disrespect at all and love being able to assist helping people build a great system, they need a dedicated thread in BOLD lettering with the title "AVR users please click here" lol, you will get the odd person who doesn't find a difference in going the way of a separate amplifier while people like myself find it was the biggest improvement they made especially at high volumes, my XPA-1L's rock the house dude  Chad |

There goes deltadube with his monoblock way of thinking trying to corral you into becoming a member of his elite society. LOL
HE' a good at what he does. LOL
Really though it's the best way to assure your speakers craving for power. I was not always in the belief that more power means better listening pleasure until I became a member of the Emotiva forum. I originally had a Outlaw 7700 amplifier driving my B&W 804S speakers and I was not totally pleased with what I was hearing. I new I could get more clarity and definition in the highs but was not sure a stronger amplifier would help. There are many posts about this theory on this forum and others, believers and non believers, but ultimately it is your decision.
I chose the RED pill and believed.
I purchased two XPA'1 gen2 amplifiers and I have never looked back. They added more dynamics and headroom in my system. If you do decide to invest in stronger amplification be it MONOBLOCKS or a 2channel amp the suggestions above are good ones.
My advice to you is very selective and predujucial. The XPA 1's will have you humming all day long.

have a 1200 cubic foot room. 7.1 Def tech mythos lcr, some Ok surrounds. Subs are the towers, a Hsu vtf 15h and am building 2 horn subs. no treatments as of yet. I listen at high volumes very regularly, usually 2 channel music, 7.1 movies. Nice set up. Unless you have the -L mythos, you only have one set of binding posts on your speakers. So you won't have to worry about bi-amping, or bi-wiring. Emotiva has several amps which will take your stereo listening to a new level. What I'm worried about is that your receiver won't be able to keep up with them on the other channels. I'm afraid that the second you go to 7.1, the difference in quality, as well as quantity, will be aggravatingly obvious. Your Onkyo is rated at 100 watts per channel with two channels driven. That means that when you switch to multichannel mode that the receiver will drop power to all channels in an attempt to keep them even. My suggestion is that you start with an XPA-5 first. It will triple the power that your system is putting out now on all but two back channels. (You may not notice the difference on the far rear channels). Then, if you like what you hear, buy an XPA-2 or a pair of mono-blocks (my first choice) for your stereo pair. My room is 2500 cubic feet and an XPA-5 will fill it with so much clean power, that if you want to talk to the guy beside you, you have to yell. |

No doubt about it, the UPA-1's are if I'm correct $450 for the pair shipped, these were my first amplifiers and to this day I wish I kept them, I would love a set for a second system if I had the funds and the space to accommodate it lol. |
