    I've been following this "be" guys threads and have come to a couple conclusions.

    1. The guy is one of those brand lovers to the death. Chevy, Ford, Dodge, Sony or Onkyo........put in any brand and there will be a die hard. Can't change or reason with people like that. When the AVR smoke checks, he'll buy another of the same brand and chalk it up to just a bad piece that got through QC.

    2. He's not here for advice, perhaps trying to salve his buyers remorse by saying his stuff is .........?

    3. Some of the car analogies don't make sense to me but I overlook those. He does not know cars either.

    You folks have given him some pretty good, sound (no pun intended) advice which he chooses to ignore.

    Gordo

    I am not ready for amplifiers. :p

    Then what do you people think about B&K AVR 507 S2 ($3,300) or Arcam AVR300 ($2,000)? They are receivers too, and no one has said anything bad about them for using with the LSi's. Can anyone tell me why it has been the case?

    But if anyone of you guys pisses me off, then I might just go ahead and spend another $2,000 for the amplifiers! :rolleyes:

    Jeez we even have newbies giving another newbie advice & it's not getting through!

    As I stated before, just put him on ignore. Saves everyone time, typing, & aggravation!

    Wow you found the solution. Run out and spend $2000-3000on an AVR. Brilliant. What an F-tard. Thanks for wasting our time. I hear Bose calling your name. Bub By.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects.

    Hey...

    I'm a noob I know :o

    What did you get in any sort of your reading comprehension exams? You would know that what you think I am saying is not what I meant if you read what I had written carefully; don't let people readily discover that your I.Q. actually is a two digit! :D

    Who says I am spending $2,000 for a receiver? I know at least dkg999 and jayman 1975 are, but it is not me. And how did you know that all the cables I use for my set-up are Monster series cables; is it because you use something fancier? I am not living in your level, and I don't plan to! :cool:

    Thanks BP it is actually 135. How have you done on listening exams?
    If you had half a brain you would realize that people are trying to help you. Why in the world would you spend $2000 on an AVR? You can get a nice Pre, and an amp under that. I guess you are just a little to stuck in your ways to listen when people give you good advice.

    Forget it dude you are just way to thick to even bother with. Go get your Onkyo, and be marry. You will be bliss, and never know what you are missing out on.

    I think we are being too hard on BE, he saved up his allowance for years to buy the LSi's. It would take him another 5 years if he needs an amp also...

    Yeah I was kinda thinking he may have a paper route or something. I remember when I was running 110wpc receiver, and thought it was the bomb:cool:

    Hi, guys. I just wanted to let you know that I changed my mind again and decided to get $500 7-channel Emotiva LPA-1 amp that produces 225wpc @4-ohms for 5 channels at THD of 0.04%, 1 kHz, all channels driven. Its 6th and 7th channel only produce 95wpc; so I will just use my Onkyo 805 for those two for my back surround speakers, and not use the Emotiva's. Like I said, my receiver has certified 4-ohms performance; so I am sure it will produce enough currents for at least two LSi9 speakers simultaneously around 150wpc, THD of <0.05%, 1 kHz, before clipping; and it is only for surround back speakers that you can live without or that produce sound which is the same as surround side speakers in most 5.1 movies. I don't want to waste my receiver's amp section as well as in this way, LPA-1 will have to supply currents only to 5-channels as supposed to all 7-channels, thus do a better job for those five channels, namely two fronts, center, and two surround sides.

    So I decided to spend $800 on LPA-1, amp stand, and RCA cables instead of spending that same $800 on upgrading my receiver to Onkyo TX-NR805 with a toroidal transfomer and separate transformers for audio and video processors. LPA-1 has a toroidal transformer too; so my current receiver Onkyo TX-NR805 would have to use its regular transformer to supply currents to both audio and video processors, and two channels loaded with 4-ohms surround back speakers, which I believe it would be able to handle. Hopefully, I will get better sound quality in return this way!

    LPA-1 for $500 of course.

    Thank you everyone for your advice, even cfrizz who likes to ignore me, because I wouldn't have learned about Emotiva product without him mentioning it to demaples for the first time! It only took you guys 10 days to convince me to go for an amp instead of a receiver! ;)

    Why in the world would you spend $2000 on an AVR?

    I did...I didn't have enough space at the time in my rack to add the amp. Only thing is the Arcam was $2000 worth of "music first" design and build quality. No auto-setup, no HDMI switching, no IPOD ready, no XM satelite compatible. I'm sure the $2000 ONK has all of those frills and piles more.

    If I was going to do it all over....if i had the room for seperates to begin with...i would not have bought the expensive reciever. But for the limited height allowance in my rack and no room for an external amp....the Arcam was exactly what i needed.

    I am still trying to get my head around the idea of pushing speakers with an amplifier. Some speakers are kind of top heavy; if you push them, they might fall over...

    If y'all would like to get some additional insight as to the paramaters that matter when it comes to amplification, you might want to peruse some of the "amplification" articles at: http://sound.westhost.com/articles.htm

    Not a bad primer on the topic.

    Congrats be, should be a great amp, I have heard very good things about the emotiva gear, they seem to be great bang for your buck.

    de, seems a little pricey, once you get over $1k alot of options open up. Should be a very nice amp but I would never buy it as it doesn't double down into a 4ohm load, has fans, and I am not a big fan of class H.

    Which one is class H? Emotiva?

    Is doubling down into a 4 ohm load a good thing? What kind of amps do that?

    There are a pile of amps recomended on here that don't double down. I wouldn't get to hung up on that issue.

    Agreed. Most amps that are affordable don't. The ones that do cost BIG bucks!

    Read the specs of the amps that claim they double the power into 4ohms. The distortion specs are often much higher than the ones that are willing to compare apples to apples.

    Looking at the specs on my Cinenova and it has lower distortion at a 4ohm load then a 8ohm load, and it doubles down just fine. All Icepower amps I have tried keep the same distortion rating while doubling down. Sunfire is another that comes to mind. I guess these seem to be the exceptions to the rule though, as many brands don't.

    Mighty, a amp doubling down is a show of its ability to produce current. The closer it can get to doubling power into a 4ohm load the better. It also shows that the amp will be more stable with not only lower impedance speakers like the LSi series but also ones with large impedance swings.

    Currently have LSI 15's front, LSIC and LSI FX surrounds. I purchased a 3808 back in November and didn't take the 4 ohm impedance into account.

    I currently have a 6.1 set up and will eventually go with 7.1 once I get an okay from my better half to give up the garage and build a dedicated HT.

    I need a suggestion on an amp that I can team up with my 3808 and not break the bank. I've read in some forums that AVR's don't make good pre's so suggestions are welcome.

    Thanks in advance.
