    Sorry, was not trying to be an arse. I think 99% of PA equipment has no business being used for home use - its just these amps in particular seem to be diamonds in the rough. They are so proving to be that 1% that sounds better and performs better than they should.

    Performing better than 99% of pro amps means nothing to me.

    I have a crown amp and yes its loud, drives my sda's ok. however, I also have a new parasound 2250 and it does loud just the same for me. My only regret is I DON'T have your skills to build myself a custom amp like you have, which would be cool to know how to do!!!!

    I'm still not sure what you meant with the xls being what matt polk intended. I read on one of the links provided that there is some roll off at the lower level being one difference between a pro and a home amp. With a subwoofer I suppose it wouldn't make a bit of difference, or even without a sub. The link with the humour was quite funny indeed, thanks for that one!
    I am curious though what the pros and cons are or the trade offs between the advantage of power, and the advantage of an amp made for the home. All kidding aside, there is enough emo bashing that it makes sense to see if a proamp can be advantageous in some situations. With a limited budget and a noisy room it probably makes sense, but a somewhat dedicated listening room with everything top quality and sound treatments I would assume it would be disadvantageous.
    I think too some of my potential issues with setup now would be cured by simply upgrading my crossovers and upgrading the caps on my old amps.

    These threads pop up from time to time but I still glean good education out of them. The op is a polkie, so I'm listening with an open mind.

    I'm newer to all this hi-fi stuff but have been working in 12 volt audio for 15 years my first thought was to buy a crown amp or Cerwin Vega pro amp and drive my rta-12's but would just would hate to ruin my speakers. I've read allot of opinions and still have no clue if its safe, okay or just going to be loud. Even with running it on clean power . Well my first thought was to hook up my 80 amp ac to dc converter and run my old 250 x 2 class a/b car audio amp.

    The XLS is cool but the XTI is better - has a lot more useful features, bar none. (Check out the Harmon HIQNET Software) - ridiculous to say the least

    The XTI only has a 100db SN in all versions except the 6000 series VS 103db with the most of the XLS series. For home use, that extra 3db will make a difference.

    The XLS series also has RCA inputs where as the ZTI does not.

    The XTI cost more than the XLS and though they might offer some extra features and software, the only plus I can see is that you can buy models with a higher power rating.

    From what I have researched, even Crown employees use the XLS series for home audio, and its the amp they recommend for home use from their lineup.

    The XTi's DSP software is powerful. But if you don't need it, you may as well look elsewhere.

    Oh oh.......good luck to you in coming here and trying to tout the benefits of pro amps to be used on the big polks. I'm wondering if you may have masochistic tendencys
    In all honesty though I'm thinking it would take more than a pro amp with lots of wpc to better those beastly looking Nak's that you have right now.

    The bass guitar guys like Crown Macro Tech(not common ground SDA unfriendly),Crest Pro 7001 series,and Crest CA series. I have a monstrous CA9 and It's on like Donkey Kong son.I just don't like how my sweet spot of operating power seems to reside at directly the level where it gets the hottest.

    Now not to start a war or any thing else. I do have a QSC Gx5 power amp. I did "try" it on my speakers..not for long and did NO critical listening on it. IT dose have a Class H power supply in it which i don't have a clue if thats good or bad to be honest. I have it, it was sitting there so i tried it out..thats about it. My normal amp is the Onkyo M-504.



    I tried the RTi12's on it..the first thing that hit me is they were brighter...so this is not a "warm" amp per say. I plugged in the SDA 1C's...for some reason they did not come across as brighter.

    I did not find that the amp sounded like junk...BUT....I did not play it long, did no critical listening,

    plus probably had too many beers to boot. Then just went back to the Onkyo..so no real statement can be made except it didn't sound like complete junk....LOL NOT a glowing report..but it does work.

    Maybe at some time i will get behind the rig again....and make some kind of useful comparison on the 2 amps

    Over at the site/thread that's linked, they throw a few jeers at Emo for their refusal to provide any demo pieces for purposes of comparison shoot-outs !

    They were designed to amplify. I'm using a Yamaha PS2500 over the Crown due to Aesthetics and over my old Marantz mono-blocks the Yammy certainly delivers the goods.

    Not sure how an Adcom, Rotel, Crown etc know what kind of speaker it's hooked up to. So how does one design an amp to work with concert arrays?

That doesnt mean you cant repurpose a pro audio amp, however as stated repurposing isnt for everyone.
    Can you substantively back this up? My Yamaha has a fan and it never comes on. Same with what I have read about the Crown. I picked up mine new for $369 from Guitar Center.

    All the reading I did on my Amp and the Crown is no one at AVS/AH/HTE have ever complained about fan noise. Not all pro-audio amps are meant for road use. Some are specifically made for installed sound: studios, H.O.W and other F.O.H applications.

    I was just referred about a week ago to a thread at Parts Express Tech Talk were a long time member there picked up a Crown on suggestion and is now offloading his Adcom and Rotel gear.

    From the HTE thread:

    Application(s)
    I was turned on to Crown amps, or should I say professional amplifiers on a whole, by a friend of mine Ray Coronado of SoCalHT. Ray is a professional systems calibrator holding certifications from both ISF and THX as well as Denon and Audyssey. He and I were chatting one day about amplifiers, he knew I was in the market and looking for something for my new studio, and asked if I’d considered pro amplifiers. I had not, so I quickly ventured to my local Guitar Center for a listen, where, I was completely bowled over. I was so impressed that


    Ray seems to make the rounds as he is featured in the 2nd most recent AVS interview with Scott Wilkinson. I sat through it and Ray seems to know what he is talking about.



    Also I bumped into Wolf from Parts Express Forums at the Dayton Tent Festival. Not expecting anyone to know who he is but he is one of the prevalent speaker designers there and he runs Crown.

    Sounds like you're arguing from a HT perspective. HT has nothing on a dedicated 2 channel in terms of details. While Pro amps might sound fine for movies (and possibly add more dynamics), in a 2 channel system, those flaws are going to become evident.

    Ok, so how do you know the XLS has no finesse? I've read from other posters on other forums where they would disagree. One that I already mentioned seems to have quite the set of ears and experience designing speakers.

    I can afford Krell or just about any other brand. I bought my first Crown to do my own in home auditioning. I am buying more, not because they are all I can afford, but because I am very impressed by the sound.

    The whole point I am trying to get across is these amps sound pretty impressive. They sound better in my setup than my PA7s or any of my Adcom's did. Are they the best amp I have ever heard, no but easily in the top 1% of everything I've ever heard.


    I simply wish before condemning them, you go to a Guitar Center and give them a listen. Heck you could even buy one, listen and return it if you are not impressed.

    If you already have a set of amazing amps, and it sounds like your hand built amps are very nice - why even bother perusing this thread ? Not trying to be rude by stating that.

    I love my big Polk's and to hear fine home audio equipment - also enjoy reading these forum's with an open mind.

    John you are getting all bent out of shape over this thread? The OP, or anyone else in this thread for that matter, have not said a thing about that pro amp being "THE" amp to have. You say "my money, my house, my gear" etc etc. Same with the OP. He is simply stating his experience and opinion of this amp. Your comment about the OP trying to get people to "troud down that path", "turning EMO" etc.....where has he done that? You even said that you had no experience with this amp! Your "childish bs" comment, I actually did laugh a little on that. Considering your other comments in this thread.

    Be happy the OP is happy I say.

    man some of the posts here seem to be very strongly opinionated. Which is great because that's how things develop. I have not used pro gear in my 2 ch rig and have no plans to do so. however, I can see that for some it may be a viable option. Everyone does not have the same budget, or ears for that matter. By reading up on the Crown XLS it seem they have addressed a very major issue with the Class D power supplies (at least they claim to have). If this is the case these amps could very well sound better than many other pro class D amps. They also incorporate PWM circuitry (can anyone say Carver). Class D has been around a while and has improved tremendously over the years. Hell Polk used to make them for car audio (not sure what they make for 12V now). A class D amp with a rugged case and optional XLR inputs doesn't make it worse than other class D's. Most audiophiles are well aware that Class D hardly ever comes close to class A/ AB when it comes to distortion and invisibility in the signal. But for someone with a tighter budget that what a Krell will allow may do very well with them. Especially if they are improved designs. To each his own. For those who wish to use them, enjoy.For those who don't, enjoy as well. That's what this hobby is all about

    Thanks ! Not trying to ruffle feathers. Just thought there might be another forum member who would be happy to know that there are amps out there that sound great, have huge power reserves, and are compatible with big Polks at a very reasonable price.
