Been shopping around a lot for speakers and ended up with the deal at Fry's on a pair of Lsi15s. Very happy camper so far. Just hooked speakers up and listened a little with my HK AVR 435. It seemed to have enough power for low volume, will just have to wait and see how it does when I crank it up. I've been told that I really should get a amp that works in 4 ohm. What do you guys think?

    For the 15s, I am guessing separate amplification will be a night and day difference. Suggestions on here tend to be 200 watts/channel or above @8OHMS. There are a lot of options, so if you are looking, a price range is always a good place to start if you are looking for suggestions.

    Welcome to the club!

    A budget would help greatly.

    Sorry guys, should have posted a budget. I'm really hoping to stay at $500. This is the one I'm really thinking about getting:

    http://www.emotiva.com/lpa1.html

    With this one when I upgrade the center and surrounds I'll have the power and channels for everything. Speaking of which, what would be a good center channel to go with the Lsi15s? The best price I see on the LsiC is about $400 shipped. Can I do any better with a newer center?

    The LSiC is a great center channel and will match your LSi15s the best. You will definitely want amplification for all of the LSi speakers -- I wouldn't run them without it, but that's just me.

    Welcome! :)

    Welcome to te forum; be careful with cranking it up.....not enough power can damage your speakers faster than too much power.

    That's a nice price for that Emotiva 7 channel amp. 125 WPC at 8 ohms will do a lot better than your receiver, but the LSI's can still use more power than that; not that they won't sound good, but they have more potential.

    Welcome to Club Polk.

    I suggest you do a search here on the board about amp power & the LSI's. In particular a couple of members got that amp for their LSI's and found that it didn't really do the job.

    It takes a lot of power to have them operate to their full potential. So I suggest you continue to save more money, and start looking at Audiogon for a 200wpc @8ohms multichannel amp. You will get more bang for your buck buying a used one.

    Brands to look at are: Parasound, Rotel, Outlaw Audio, Sunfire, B & K, Adcom.

    Thanks everyone. Nice group here. Well, so far anyway. I am fairly new to this home theater arena and it's been years since I was into stereos so bear with me.
    I live in a relatively small apartment so I'm not looking for a lot of volume just good clean sound. Do I really need to go with a real high output amp? Would that high output just give me volume or would it give me better sound even at low volume? Would I be better off just to power the 15s with another amp and run center and surrounds through the receiver? I'm probably getting the LsiC soon and leaving my Hsu surrounds for now. I like the idea of having a 5 or 6 channel amp.

    The common misconception about having a high output amp is that it will just be very loud. The real benefit of it is to get good clean sound at ANY volume. This is the most major improvement & worth the investment of getting 200wpc or more!

    I am able to play my system softer than ever & still hear it extremely clearly in my apt. with my neighbors being none the wiser!

    When I upgraded from 170 wpc to 425 wpc it wasn't volume that I noticed at first. It was the subtle little sounds like fingers sliding on the strings in acousticals or drum stick licks and the singers breathing. Sure the extra watts lets you turn it up to painful levels but the purity of the sound at fun listening levels is hypnotic. I had always liked listening to music once in awhile, now I love to listen to music often.

    I have really started to enjoy watching/listening to concert HD DVDs. I've found several of my favorite bands lately. Led Zeplin, Moody Blues and Queen. I have several SD DVDs too in DD that are almost as good.
    I'm looking to get an amp ASAP then a LsiC. I've changed my priorities.

    Ok, so I've looked around at different amps and it seems that it will be a LONG time before I can afford one of the brands you guys suggested, even used. I had mention the Emotiva LPA-1 above and it seemed to get a luke warm response. I searched on the forum and got no hits on either the model number or brand name. I see on most amps the power is rated differently for 8 or 4 ohms, why is that? The Emotiva only says that it is " Completely stable into 4 ohm loads". Is it that 125 watts isn't considered enough to drive the 15s well?
    My brain is feeling the strain of doing all this research. Help me !!

    Bingo! Some have recently tried it with their LSI's & were very disappointed.

    The higher wpc you have at 8ohms is the more you will have at 4ohms. The more power you give the LSI's the better they will sound.

    So just keep watching Audiogon & continue saving money until the right deal comes along.

    This may work out well for you and drive the 15's quite nicely.

    When you add the center and rear speakers, you can run them off the AVR initially and when funds permit, get a 3 or 5 channel amp to drive the center and surrounds.

    At least it is a way to check out the benefits of a nice amp and determine if the difference is worth upgrading to.

    cfrizz,
    You've said a couple of times that people were disappointed with the Emotiva. How/why were they disappointed? Here's something I got off their web site:
    Rated Power Output: Channels 1-5 (All Channels Driven at 0.04%THD, 120vAC/ 60HZ supply) 8 ohm: 125 watts / 4 ohm: 225 watts

    Is that not enough power? Is it something in the sound? Just trying to figure out why they didn't like it. I found more reviews and everyone that had it had positive things to say about it.

    There was one person here who was disappointed. I believe if he would have let it break in and if he used some better interconnects, he would have been much happier.

    I'm considering giving the LPA-1 a try also.

    I don't consider the 8 ohm: 125 watts rating to be enough for the LSI's. The people who have been happy with the LPA-1 I don't think were driving LSI's. (Oops they were driving RTI's.)

    As I stated before, The higher wpc you have at 8ohms is the more you will have at 4ohms. The more power you give the LSI's the better they will sound.

    Do a search here on the board, there are probably thousands of threads by now about LSI's & what kind of power makes them shine.

    The reaction to the Emotiva has been a real mixed bag. Some have been happy & others have been disappointed. Here is a good thread about the Emotiva.

    Welcome to Club Polk. I like Adcom, and Parasound. I don't get to hung on watts although you can get 325wpc Adcom GFA-555 for around $350. I also like the Parasound designs.

    I had LSI9's driven by LPA1 , sounded great except for a bass hump that I had that was probably due to my room/ setup. or I would still have the 9's in my system.

    The LPA1 is 225watts @ 4ohms, plenty of power and slam for the LSi series.

    While it would be great if you could do as cfrizz recommends, and get a used 200 wpc @ 8ohm amp,(would probably be 300watts @ 4ohms) finding a multichannel one for under $500.00 might be hard.

    I say try the Emotiva and let your ears decide, they do have a 30 return policy if it doesn't work for you.
