    Are you saying to purchase a pre/pro with a cheap pre-amp section and DAC's, to only connect to an amp to amplify the crappy sound?

    No, I did say within reason. My AVR was inexpensive (to me anyways, $500-$600, don't remember) and produces very good sound through my amp.

    Money seems to be an issue here. I see no point in spending a mint on an AVR to drive LSi speakers. I don't care how much money you pump into an AVR, it's never going to sound as good as a decent AVR or Pre/Pro with a good amp.

    Just my opinion having set up my LSi speakers in different ways myself.

    If you're going to insist on staying with an AVR and not upgrading to an amp down the road -- get different speakers.

    A good AVR is just as good as equivelant seperates any day. This whole discussion reminds me of the same discussion back in the 70s when it was receivers versus seperates.

    If you want an AVR I recommend the Sony STR-DA7100ES. I have one, and it sounds great with four LSi15s and one LSiC.

    You can get one for $1100 on the net.

    Great to some people sounds pretty average to another person.

    Have you ever even tried to demo you setup with a separate amp and a dedicated 20A power circuit? I am guessing you haven't.

    The only receivers that come close to seperates are the mega buck top of the line ones from say B&K and Denon.Still even at 3500-5000 g's,seperates will sound better.Running 4 LSI 15's off a Sony receiver ?? Well,far be it for me to tell you otherwise but,really,you can do better.

    Are you referring to the Harman Kardon AVR635? If so, depending on the size of the room you could be ok. We're driving a pair of LSi9's off a AVR435 here in the office and we haven't had an issue yet. Granted the room is relatively acoustically effecient. Now a set of seperates will of course sound better and get you higher volume levels. But as long as the room is small enough and you don't push too hard I don't think you will have a problem.

    Of course you can do better. There always is something better. However, that does not mean that an AVR cannot drive LSi speakers and sound just fine. To say otherwise is just stupid, and demonstrates a lack of basic hi-fi knowledge along with a clear lack of understanding of electronics.

    The ones on this group who are constantly stating you need seperates for LSi speakers are card-carrying graduates of the Spinal Tap School of Engineering -This Amp Goes To 11.

    You seem to claim a lot of fact in a post centered around an opinion.

    LSi15s don't sound great on only an AVR to my ears.

    You seem to equate amp with loudness. Loudness has little, if anything, to do with why most of us suggest an amp, although that's one of the small benefits.

    Thanks for calling us stupid, though. :rolleyes:

    What I have bolded is the problem. Speakers are meant to be played & heard from a comfortable distance to whatever volume you deem comfortable to you.

    I don't want to have to sit on top of them with the volume hardly turned up in a tiny room to hear all the details that are in the music. Just so I don't put the speakers at risk or the receiver. That makes zero sense.

    I want to hear ALL that any speaker has to offer. To do that I get equipment that will achieve that goal.

    Just about every LSI owner has come on & confirmed that the more power you give these speakers the better they will sound. Power costs money. If you don't want to spend the money, get less demanding speakers.

    Or get them & proceed at your own risk, but don't constantly try to get those of us that KNOW that somehow we are all wrong about the power needs of these great speakers just so you can save yourself a few bucks.

    They don't need both a separate preamp & amplifier. But they definately DO need a separate amp, or you are putting some very expensive speakers at risk, or wasting their full potential.

    I have LSi's.
    I also have a Sony STR-DA5200ES, their current flagship AVR. It does a very good job at driving my speakers and they sound quite good. That said, If you go the AVR route, you can certainly find one that will get the job done.

    But, there are a few reasons why an AVR alone might not be the best tool for the job.
    1. AVR's can get a little warm. A little too much IMHO, besides I already have a toaster.
    2. There is nothing like your AVR rolling off into protection mode right in the middle of a demo that will make your curse the day you decided not to go with a amp. Or perhaps beer & remotes are a bad combo, nah.

    At any rate, I have an Outlaw amp as well. Now my LSi's sound amazing and my AVR runs cool as a cucumber.

    Yes! LSi's sound better with more power, and as stated before this can be said of most speakers. But, to go as far as to claim that you are better off with a lower line of speakers just because you are running them with an AVR instead of out-board amps is stupid!

    I've heard LSi's vs. RTi's vs. R & Monitor series driven by AVR's more times than I can count, and I would still take the LSi's over any of the others!!!

    While I do agree that the LSi's may sound better, when run off most AVR's I do not think they justify their higher cost. When run correctly - they are most definately worth it.

    I use my LSi's for mostly home theater. If I had planned to run them mainly off an AVR, I would have gone with the RTi line and been very happy with them. For a music system, the LSi's may have justified their cost over the RTi line just with the more laid back sound, but for my needs I would have gone RTi with an NAD reciever and I am sure been happy.

    As it is - I love the LSi's for home theater. (I am not using an AVR though)

    P&H/K, I would give the H/K that you already own a chance with the LSI's before buying anything else. If you like the sound of the H/K, I doubt you will like the Yammy. I can't stand the brightness out of the Yamaha AVR's. The amp section in H/K AVR's are very strong.

    Having said this, if you can, somehow, some way, find room for an amp, take the money you were going to spend on an AVR and pick up a used amp at least for the 15's. You will be much happier.

    At that price point? No, I think it wouldn't make a lot of sense to shell out for brand new LSi15s and drive them with only an AVR. If cost is an issue, I don't know why you'd be buying the LSi15s in the first place. I'm speaking from the standpoint of someone planning to build a system. If you already have them, well, then....whatever, but if you were planning a system no way would I pay $1,500 for a pair of speakers and drive them on an AVR -- that makes no sense to me. I'd buy speakers that don't need an amp driving them -- like the RTi line. Yes, the LSi15 doesn't need an amp driving them, but even Polk reccomends it -- and most of our ears around here hear a huge difference. The LSi line on an amp is world better than one powered by an AVR.

    Wow, just wow. THis has been an entertaining read. My points:

    1). The NAD mentioned in the OP will power the LSi's just fine but may not have the ideal charactoristics.
    2). IMHO: Avoid HK and LSi combo like the plague. Unless you really don't want to hear the tweeter, then go ahead.
    3). AVR's are a great stop gap until you upgrade to an amp down the line. If this CAN'T happen, you'd be better off with the RTi series and better electronics/subs.
    3). Amps in the sub $1K range are substantially better at their job than a comparable AVR.
    4). Once you get into the $2K+ range, AVR's are just as good, amp wise, as a seperate, but once you get to that price range the flexibility of mix and matchin pre's and amps to match your tastes should pus you back into seperates. If you are at that price range and don't care about the fine tuning, I'll sell you a BOSE system for $4K that you'll be happy with.

    Continue on with the bitchfest...

    I would like to add that, financially speaking, separates hold their value much better than AVRs. . . especially amplifiers. . . and really especially used amplifiers.

    If you buy a $3K AVR, it will be worth maybe $1K in a couple years. If you get a real good deal on a used amp for $1K, it will be worth almost $1K in a couple of years. Pre-pros depreciate a little faster due to changing technology, but amps hold their value very well. Hell, Carver amps have been appreciating like crazy as of late.

    So, basically, you can blow some money to get the enjoyment of a very nice AVR, or you can invest your money in a good, used amplifier and suitable pre-pro.

    Demi,

    Are you of the opinion that LSi's don't sound as good as RTi's when powered by an AVR? If so, I totally agree with your advise here. However, In my personal experience, I prefer the sound of the LSi's to the RTi's regardless of amplification. Therefore if I was tied down to an AVR due to lack of space, and had enough in the budget for the LSi's, I'd be all over them. Even if I knew I wasn't getting the full potential of the speaker, I would not deprive myself of a sound I prefer just because I wasn't using the speakers to their full potential.

    AVR with plenty of Audio and video inputs and preamps out should last a long time. Just add amps as needed; mixed don't stir.

Even if I knew I wasn't getting the full potential of the speaker, I would not deprive myself of a sound I prefer just because I wasn't using the speakers to their full potential.

    I am arguing that, but I'm also taking what was said by the poster in this thread.

    First off, how is there not space for an extra 2' x 2' x 2' (being overly generous) square box in a room housing a home theater? :confused:

    That question went completely unanswered.

    A follow up question to that would be that if there wasn't space for a 2' x 2' x 2' Amp & AVR/PrePro in that room, how exactly are LSi15s the right speaker for that room? :confused:

    Secondly, it seemed money was an issue as well. If that's the case and you want the best sound possible, I would buy the RTI line, a 5 channel amp, and a AVR or Pre/Pro.

    So on that point, when cost is an issue. Yes, I would argue the RTi line powered by an amp would sound much better than the LSi line powered by a low end AVR.

    Sure, you can suggest a $5,000 AVR, but he's not going to buy one. My suggestions were merely in the parameters he's working in.

    I could not rationalize spending $3,000 on speakers that thrive on amplification and powering them with only a $1,500 AVR.

    Absolutely ridiculous, and makes no sense at all.

    The last 50 years of audio and high fidelity research has shown that speakers are the single most important component of a hi-fi system needed to achieve good sound. Research as shown that even a mediocre electronic system will sound better with better speakers. The key area to be concerned with is speaker efficiency and LSi15s are rated at 88db.

    From the LSi15 manual, which I assume was written by Polk and reviewed by their engineers.

    RECOMMENDED AMPLIFICATION/
    20-250 watts/channel

    EFFICIENCY (1M,1W):
    88dB

    You may not NEED an amp for ths LSI's, thats true. But I would feel I wasted my money spending the extra money say from the RTi-10 to Lsi-15. The extra cost (to me) would not be worth the sound improvement from one to the other.
    As far as speakers being the single most important item in your system. I think thats a load of crap. If you want good sound all peices must compliment the other. If you have a junk source, a speaker up grade will only get you so far. If you had an audiovox receiver I don't think Lsi's would sound any better then a set of the low end Klipsch's from best buy.

    The last 50 years of audio and high fidelity research has shown that speakers are the single most important component of a hi-fi system needed to achieve good sound. Research as shown that even a mediocre electronic system will sound better with better speakers. The key area to be concerned with is speaker efficiency and LSi15s are rated at 88db.

    From the LSi15 manual, which I assume was written by Polk and reviewed by their engineers.

    RECOMMENDED AMPLIFICATION/
    20-250 watts/channel

    EFFICIENCY (1M,1W):
    88dB

    What a crock of crap you peddle. Perhaps your extreme view is for effect. If not you are seriously misinformed.

    Yeah, hey, wtf?

    Do you have a point or are you just a numbers guy? So are you advocating that for a $5K system I'd be better off buying $4700 speakers and the other $300 on the rest of the parts and that system will sound better than one where I spend $2K on speakers and $3K on everything else? If so, that may be the most idiotic statement made on these boards outside of the gas price threads.

    As for the power thing, most people won't ever use more than 50W on anything other than a sub. That said, most AVR's do a very piss-poor job of producing the first 10W compared to an amplifier and can hardly ever generate more than 30W all channels driven. Things like slew rate and damping factor are typically horrid in all but the highest end AVR's
    There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction. Nine-tenths of the rights he bellows for are really privileges and he does nothing to deserve them. We not only acquired a vast population of morons, we have inculcated all morons, old or young, with the doctrine that the decent and industrious people of the country are bound to support them for all time.-Menkin

    ok, bbeacham, where is all this research you are talking about? Maybe it’s the same research that BOSE is doing?

    I firmly believe that the amp is the most important part of the system. If the amp can't perform for the entire impedance range of the speaker, then it’s going to have dynamic range compression at some (if not all) frequencies. For me this is unacceptable because to me the dynamic range is the most important characteristic of good music. Yea, I like it to be clean and clear as well, but I can handle a little distortion if I really have to (for instance when I am listening to my car system). What I can’t deal with is the laid back sound that comes with dynamic range compression.
    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've had more productive arguments with my 7 year old. Some people just don't get it and are unwilling to learn.

    The individuals who are constantly stating that you cannot use LSi speakers with an AVR, but, rather, need to use seperate components, are simply trying to justify their own equipment choice. Apparently, they are scared that somebody might spend $1000-$2000 on an AVR, use it with LSi speakers, and actually enjoy the experience.

    So go ahead and buy the LSi speakers. You can't go wrong. The LSi speakers will help you get the maximum sound out of your system. If at some point in the future you decide to upgrade your electronics you will still be happy with your speakers.
