    Just do a search of the forum. There are tons of threads dealing with this topic.

    I think you will find that most will recommend using a preamp/processor (or AVR with preouts) and seperate amp or amps.

    Adcom, Rotel, Parasound, Sunfire, Carver, Outlaw, etc...

    I have no room for a pre/pro it must be an AVR.

    The NAD would be a fine choice.

    Others you could consider would be: Outlaw, Rotel, Denon, H/K, Pioneer Elite, Yamaha, Onkyo.

    Then the LSis aren't for you. You really need a separate amplifier so it can focus on powering the power-hungry LSi15s.
    That's not to say that there aren't any AVRs out there that are capable of doing the job, but you'd be spending thousands more than you need to. I would not recommend the NAD 753... though NAD makes great stuff, I don't imagine the 70 wpc would be enough to power four LSis.

    I have the H/K 635 and love it. But the H/k will not drive 4Ohms.

    How are you limited for space? Maybe you could stack an amp and pre/pro for space conservation?

    The NAD T753 gives 200 watts dynamic power in 4 ohms.

    The NAD T763 puts out 300 watts dynamic power in 4 ohms. The LSi 15s max watts is 250 what more do you need?

    The nad receiver will do fine. It'll probably handle them better than the h/k, but then again I've never heard the h/k pushing anything better than a pair of rti10's. Yes, seperates might be better but you can always move onto them later if you have more space.

    Do some searches around the forum. You'll find that their rated power is significantly underrated. Many members throw 500+ watts @ 4ohms at these speaks.
    Not to say an AVR won't be capable of handling these, but they really are meant for separates.

    Start with the NAD T763. It will drive them better then your HK. The issue with the 4ohm speakers is current (amps) the more the better.I was running 9's, 7's and Lsic off my Rx-v2500 (130 @ 8ohms) and it worked. The amp section in the NAD is much better then the Yammi but still might not bring out the true performance of the Lsi's.

    The LSi series doesn't need outboard amplification to sound excellent....buy the right gear in the first place. The LSi bar for me is high current, 4ohm load capable, all channels driven.

    To be honest, I was not really happy with the laid back NAD and laid back LSI combination for movies. I swapped out the opamps in my NAD (changing the sound character of it) and love the sound I am getting now.

    Different strokes for different folks. In my case it was using an NAD pre/pro so it had nothing to do with the amplification part of my system.

    Just wanted you to be aware of it. (many other have used NAD AVR's with LSi speakers and love the sound so I may be in the minority here...)

    McLoki - I don't think your off base at all. NAD gear is laid back/warm to me also....but that's my preference overall.

    Well, "Best" is rather subjective. I am currently using a Sony DA7100ES, before that a Sony DA5000ES, and before that a Denon 3805. They all work fine and sound excellent, but the 7100ES is the "best" of this group.

    Also, I used to have LSi15s in front and LSi7s as surround, but I upgraded the 7s to 15s in January.

    AVR's will not drive LSi's. Seperates are THE way to go. Actually AVR's won't drive RTi's too well either. In all honesty seperates are the way to go with all HT speakers.

    Because everyone knows that if you purchase polk audio's midline (or god forbid top end) speakers, they will sound like **** unless you have over $11,000 worth of electronics behind them.

    Thanks for the clarification there.

    That's just ridiculous. AVR's won't drive the 8 ohm RTi's well?

    My H/K 635 drives RTi 6s as well or better than most low end amps.

    Well I said that because if you want the most out of whatever speaker you got, use an external amp.

    OK fine, you drive LSi (4ohm) off your receiver instead of a pre/pro and amp and report back and tell me how long it took for you to burn up your receiver or fry your speakers.

    If your friend comes to you with a budget of $15,000 for the audio side of a home theater and you direct him to break up his budget as $4,000 for speakers and $11,000 for electronics - he needs to find a new friend.

    anyone can suggest the top of the line. The difficult part of audio is getting something above average for whatever the current budget happens to be. For many of us - that is where Polk comes into play... :)

    I take it that you don't have any personal experience with NAD products. If you did you wouldn't be making such a ridiculous statement.

    3 1/2 years and counting, running 9's, 7's, and LSiC off an ancient Denon 2802. As long as you use common sense, and not drive the AVR into clipping, it will be fine. Work within the limits of the receiver, until you can upgrade.
