    Default pro power amp on a HT

    I'm trying to deside between yamaha P2500s rated 350w/channel. Or P3500s rated 550w/channel 8ohm. I'm using RTi A7 for fronts. And I have an avr with pre outs

    Why a pro amp as they dont have clean power? How much are these amps as I'm sure you could find an equivalent in price thats better

    You say that... but there are a lot of people around the various forums finding that amps like the Crown XLS series are astoundingly capable powering home theater speakers. I'm running an XLS-1500 for my subwoofer and Buttkicker, but I've seen a lot of people using these newer class D Crowns as 2-channel amps, with good results. Can't speak for the Yamahas the OP is looking into, but I certainly wouldn't discount pro amps.

    Onkyo TX-NR3010 9.2 AVR
    Emotiva XPA-3 amp
    Polk RTi70 mains, CSi40 center, RTi38 surrounds, RTi28 rears and heights
    SVS 20-39CS+ subwoofer powered by Crown XLS1500

    I own the Yamaha P2500. It's quiet, it powers the LSi 9's more than adequately. Replaced my Marantz Mono-Blocks (one developed hum) and the imaging, soundstage, overall presentation are excellent. I listen to a lot of classical, some blues, rock, jazz. Percussion has oomph, cymbals, bells, etc sound natural with very good decay.

    Others have been giving thumbs up to the Crown XLS DriveCore series in the fidelity department alone.

    The Yamaha has plenty of clean power. You could do what I did and go to Guitar Center and check all this stuff out. They have a really good / easy return policy also. Staff was more than willing to answer questions and help out. Heeding the suggestion of trying the pro-audio route for both my amp and now my pre-amp really worked out.

    I read a lot of positive reviews about pro power amp in a HT. I just want to know if the 500w is a good choice

    It may go unused. 350 watts is a lot of power. 700 watts gets you only 3dB more for comparison. Most AVR's increment in 1/2 dB steps.

    Interesting.. Would not think one would want to use that for there home speakers. Does it auto sense power and turn on or would you have to turn it on and off all the time?

    Would this be one of those times that a Emotiva amplifier would beat out something else? :)

    Makes sense to me that pro amps could sound good with certain home/home theater speakers. It's all in the synergy. For instance a cheap yamaha A-S500 or cheap Emotiva UPA-200 sounds worlds better with my home stereo speakers than did a Jolida 801 all tube amp. It's all about the match and mate. Starting to realize that amps aren't necessarily better than other ones, because you're not buying them to function within a vacuum. They have to interact within your existing system which is comprised of numerous components. So the "this amp is no good, but this one is" is a misguided notion. Not only that but your ideal sound has nothing to do with someone else's. As much as it sucks, you really do have to listen and discover what works best with your stuff ... to your ears. I've wasted plenty of money taking the advice of reviewers and message board pundits. Just as with music, there is no good or bad, there's what you like and what you don't like.

    I don't. There are bad amps and there are good amps. Synergy plays a role but a good amp will almost always outshine the bad one on a revealing system. I wouldnt fret on throwing a pro amp on entry level gear, but would be reserved if it came to something as revealing as the lsim, a speaker able to show the nuances in the music or track.

    That is why you don't see just any pro-audio amp recommended. Just like not all consumer amps are going to be everyones cup of tea. I have read several different posters swear off Carver (I know Dorokusai does) and Adcom as example.

    I'm happy my LSi's match up rather well with my Yammy. I think people need to be encouraged to try them out. If they don't work out just return the unit and get your money back. There was even a poster here that switched up his two Thresholds (I think they were Thresholds) for a Crown XLS DriveCore to power his SDA's and was pleasantly surprised. Not that the effort was appreciated for posting about it.

    Don't listen to anyone who tries to tell you what is good and what is bad. The very concept is fundamentally flawed. They have NO idea what you enjoy hearing and what you don't enjoy hearing. If they're lucky they have a reasonable grasp on what they enjoy hearing. What's important is that it sounds good to you and that it lasts. If the pro amp meets the criteria, then a pro amp it is. Pretending to enjoy someone else's favorite brand, make and model of amp would be a shame, particularly if it's expensive and breaks down on you. What's good for the goose isn't necessarily good for the gander.

    Possibly. But championing the performance of pro amps as a whole based off a few exceptions bugs me. While there are duds in home amp design, the majority of them have the same design properties in mind, thereby usually giving a respectable product for the home.

    You're not arguing with anything I said though, so we're good right?

    I was basing my response on " I wouldnt fret on throwing a pro amp on entry level gear, but would be reserved if it came to something as revealing as the lsim, a speaker able to show the nuances in the music or track.

    Your statement/claim seemed overly broad as to overreach. The OP was asking about a specific amp. One I own with prior experience being a Yamaha AVR and then Marantz mono-blocks. I don't see where in this thread the "championing of pro amps as a whole" persisted or even originated. That is where I had a question.

    FYI, Lexicon who is owned by Harman International, also uses the Texas Instruments based DriveCore class-D amp set in their DD-8 amp, which used in the Crown XLS amps. The technology was developed in-house at Harman partnering with Ti, and is being using throughout their lines; including active JBL studio monitors.

    While it hasn't been in this thread, it is the general tone you give off on every post concerning pro amps. I wouldn't have mentioned it if the thread hadn't been so broad. If it had mentioned the specific amp in the title, I would've stayed away. People search this stuff and when they see the 'pro amp' header, they're going to assume things. I'm trying to kill that assumption, not argue about your own beloved pro amp. There are exceptions to every rule, but I'm trying to dissuade others from starting their search for a Lexus at a Kia dealership.

    Do you care to go through my posts and corroborate the 'general tone'? I doubt it can be substantiated. I even started a thread asking about peoples experience here with specific pro-audio amps that did the trick.

    The only one going off on a general tangent (at least in this thread) is you. Two specific amps (not even brands) have been mentioned.

    Look if you don't like pro-amps for whatever reason that is fine. I don't even seeing you putting down the suggestions made. But could you stop with baseless accusations? If what you said had merit I would expect some posts of mine to be quoted.

    You could have read the original post and still shied away from the thread.

    Just so this is straight in my mind: You are making assumptions about what other people are going to assume from "pro power amp on a HT"? Trying to close the loop on your logic on that count.

    The only assumption need killing is your initial assumption that the thread title is going to lead people to look for a Kia at a Lexus dealership.

    Also the quip about 'beloved pro-amp' isn't needed. I took zero risk in evaluating the PS2500 and was pleasantly surprised. If the Yammy or Crown aren't the end all be all well neither are my LSi 9's.
