Well I've been searching through this forum and cannot seem to get a clear answer....

I just bought an HTR-5790 for real, real cheap. I'd like to buy Lsi9...will this reciever even drive the speakers a little bit, how loud?

If I need to purchase a separate amp, what kind of power and price range am I looking at??

Thanks, I'm definately new to the home theater thing!

    If you search this fourm, you will find alot of talk on this subject.
    LSi 's are 4ohm speakers.The HTR will drive them but it will most likley over haet with the volume only at a moderate level.
    More than watts for the amp, I would look for something that is 4ohm stable.

    Hi MtBMarsh- welcome to the forums. =)

    The simple answer to your question is no. For a 4ohm LSI-9 (even 6ohm LSI-7's) setup, your Yamaha does not have the necessary current to drive LSI9's beyond an 'adequate' level. And if I were you, don't take the "110x7" very seriously. With all channels driven simultaenously throughout the 20hz-20khz region- it's more like half that number.

    Use the Yamaha's pre-outs so you can hook up an additional dedicated amplifier. From a value standpoint, Outlaw and Adcom come to mind. Remember, more speakers are ruined by underpowering them more than overpowering them; and your new Yamaha will make one KICK-**** pre-amplifier. Hope this helps.

    MT, your 5790, if it's still in good condition, has a quite powerful amplification section, essentially identical to the 1400. Tests of the Yamahas have shown output into 4ohms on the order of 150 watts. The 5790 is THX certified and one of the requirements of that certification is driving a 3.6 ohm load to reference level(quite loud)in a 2,000 cubic foot room, so it should drive the LSi -9 more than just a "little bit". If it turns out that for your room and listening level you want more, you can add a separate amp in the future, but you shouldn't assume at this point that it'll be needed.

    Maybe I'm crazy but why do so many people want to buy sub par receviers for great speakers???

    If your shopping for Lsi then your shopping for a higher standard. Lsi speakers are designed for audiophiles who want more then your average speaker quallity. They are designed to go the extra mile is sonic perfection. Why would you want to power them with something thats not on the same level???

    I'll never get it. Why Why Why??????

    I was in a similar situation a couple of years back after I bought my LSi9s. The answer is simple most ordinary run of the mill recv. will not feed the LSI series the way they need to be fed. I spent 1k on an Adcom and it is the best investment I ever made. The difference is staggering. The LSI's are amazing speakers. You can run them on nominal power but I would venture a guess that you will be dissapointed. Hope this helps.

    Will it run them? Sure. Over the long haul, not good for your receiver though.

    You will not be hearing what they are capable of........knuckle under for the amp as well.

    Thanks, it is a very nice amp for the money, wouldn't give it up for anything. I think it puts out approx 125wpc into 8 ohms and 250 into 4 ohms. It's not a huge amount of power but you have to remember that it is clean, undistorted power which is just as important.
