If you have them, what are you using to power them? I'm thinking of upgrading to the LSI but I want some opinions on what you use to power them so I know what I'm going to be budgeting.

thanks
jim

I'm thinking

lsi25 fronts
lsifx for surround
lsi7 for rears (6th and 7th channel)
lsic center

your usual Lsi system. I just need to know what is best cause they are power hogs. Only opinions from guys who have had the speakers and heard them in their houses thanks

music 20%

    You'll find that people really tend to prefer the 15s over the 25s. The extra money you save can invest in a much better powered subwoofer than the one equipped in the 25s.

    There are many different amplifiers that will suit the LSis, just make sure you have...

    DRUMROLL...

    at least 200watts/channel.

    I use a Cinepro 3k6. (you can get the specs from clicking on the link in my sig)

    Cudos for checking out the amp prior to the speaker purchase. What pre-amp are you planning to run?

    These are Amps/Receiver that I have tried, and work really well with LSis (the degree of finesse, details, realism are some of the differentiating factors of why I chose to replace amps, not the adequacy to run them, current and wattage wise):

    Rotel RSX1065 - 185 watts/ch @ 4 ohms
    Krell 400Xi - 400 watts/ch @ 4 ohms (currently in place for 2 channels)
    Gemstone Blue Diamond - 400 watts/ch @ 4 ohms - 7 channels (currently in place for HT)

    hope it helps...
    I am sorry, I have no opinion on the matter. I am sure you do. So, don't mind me, I just want to talk audio and pie.

    I would look into getting at amp that can double the power as the speaker drops from 8 ohms to 4 ohms, esspecially for your left and right speakers. Polkatese is using a Krell 400Xi for this, which is a good one. Then make sure you other speakers have high current amplification as well, but it doesnt have to be as good as your left and right speakers. Also look into getting dedicated power lines installed.
    Speakers: LSi9 x 2, LSic, LSiFX x 2, Velodyne HGS-15
    Amps & Power: Rockford Fosgate T8004 x 3, Cascade Audio APS-55 power supplies x 5, and 1 farad capacitor.
    Electronics: Denon 3806, Toshiba HD-A1, & Sony KDL46XBR2
    Accessories: Anti-IC interconnects, 8 Mondo Traps from Realtraps, and Salamander furniture.

    I got it off of audiogon a few years ago. There was one listed on there not very long ago. In my opinion - they are well worth tracking down.

    The company was sold off when the originator died on the operating table during heart surgery. The people who actually purchased the company (as opposed to just the name) and expanded the designs of the 3k6 started a company called Verastarr. They perform work on the Cinepro products as well. Here is their current design.

    Mine is in rougher condition than the one I linked above - but it was cheaper as well.

    Running an Integra AVR (120WPC??) and they run like champs. We brought home several other speakers including some competatively priced Focals & some NOT competatively priced Dynaudios (still a bad idea). We listen to music 50% & HT 50%. The 25's had some real strange lows and perhaps just didn't work for our room. The 15's have an 8" passive radiator. Great all around sound, and we started out with LSi9's up front on Sanus UF34's. Moved them to the back and put the 15's up front. It would be great if you could find a place (or some friends or Polkies) that would let you borrow some different stuff so you could hear it in your space. Good luck!

    That Verastarr is one awesome looking amp! Also puts out some amazing power according to the specs. Nice...

    Since my current HT setup is my first, so i went with a used amp, which later down the road i am planning on upgrading.

    I am using an Outlaw Audio 750 165@wpc 8ohms, 250@wpc 4ohms

    It does the job, and i've never had to turn the dial greater than -8db, but then again i do live in an apartment building.

    I am only powering a Pair of LSI9's and an LSiC.

    Future plans are to get an LSI15's for the fronts and move the LSI9's back.

    I also have a SVS PB12 plus/2 to help with the low end :D ... I might just get another pair of LSI9's and spend the extra money towards a better amp.

    maybe that is for the best geting the 15's instead. good idea. As for amp/preamp, I'm going to match them from the same company, I'm looking at rotel and NAD. I've also been thinking lsi9's for fronts and one of the new subs polk is releasing

    As an owner of the NAD T163 (and I have heard a Rotel 1066 in my system) I really do prefer the rotel sound with the LSi's compared to the NAD.

    I guess it depends on the music you like, but for me the NAD/LSi combo sounds a little to laid back for my tastes. I am going to modify my NAD to see if I can get a better match with my LSi's and I will let you know how it goes.

    With that being said - I know there are some killer deals out there on NAD equipment right now. There is a new NAD pre/pro that is supposed to be released this spring/summer and I think that may be driving the price drop on their equipment. (Rotel does not have any current plans for a new pre/pro that I have heard of.) Were it my money I would go with Rotel, but right now anyway, it would be alot cheaper to go NAD.

    Good luck with your choice...

    Spec's really won't do much in terms of narrowing down a search but god gave you these two things that will. Your ears. If possible I'd recommend going to a dealer and hauling along a pair of LSi15's with you it might just be worth it. You might want to consider the Arcam AVR350 which should be able to keep pace with NAD and Rotel separates at roughly the same price points.

    Here's a good deal on a powerful 4channel amp. Then just get a monoblock, and spend significantly less than one usually would for this much power: (Deal is for today only... $699 for a Marantz 375W x 4channel into 8ohms)

    ^That looks like one hell of a deal! If I didn't have an amp, I'd buy it right now just to try it!

    Nice find Dane...

    EDIT: The only thing that kinda sets me off on that amp, is the total weight... Not much of a big deal really, just makes me wonder if the channels have seperate power supplys?

    The really nice thing is on the back of that amp that states "Manufactured in the USA"!!!:)

    700 seems like an OK price for that amp. However, the MSRP of 4,000 is just retarted! For that kind of money you can get a much much better krell amp.

    I wouldn't be supprised if they bumped up the price just so they can say it's on sale for 83% off. I would not buy this just because its on sale.

    I would not buy it just because it's on sale either. However:

    I've purchased nearly a dozen times locally from SecondAct. They have some of the best customer service around. (They even oftentimes reply to my late Saturday night e-mails within minutes!) In fact, my current TV and receiver were both purchased from 2ndAct.

    The MSRP is the price it was brand new when it first came out. They would never ask that much for it. It's actually usually $1500. I've been waiting for it to go on Deal of the Day for months... of course just last week I finally bought an amp. lol

    Utilizing state of the art, high-speed MOS-FET switching designs with spectrum spread switching technology, Marantz has created a pair of multi-channel power amps that provide power that is up to 5 times more efficient than convention class A or AB amps. This efficiency means reduced heat...

    Sounds almost like a digital amp or at least a carver design. Either way - that is a ton of power for not alot of money. If I needed an amp and didn't have a bunch of cash I would certainly give them a try. (hell get 2 and you end up with 8 chanels of high power amplification for only $1400.) - perfect for 7.1 with a DIY sub.

    Also note that the description starts with the sentance save $600. I would guess from that the normal price is $1299.
