I'm a noob and need help with my underpowered system

jo_boy04

OKAY. Here is the situation. I recently upgraded my speakers from a cheap all in one solution to LSi line up. I didnt get the towers for the fronts, instead I got LSi 7 bookshelfs because of kids. I also bought (because of recommendation from Best Buy Guy) a Onkyo SR805 off ebay. It says it will give 130W per channel. But I set it up and it sounds weak. I want to know if there are any "add on" solutions without having to resell the amp? I also have the LSiFX rears and LSiC center. thanks

I think the Onk 805 has pre amp outputs, so your best bet now is to add an amp. What you called an amp we call a receiver / AVR Audio Video Receiver. But beware not many AVR's (if any) could drive the LSi series speakers being that they are 4 ohms.

You can add an external amp for more power. The onkyo 805 has the right connections for this set-up. If you want to get the most out of those LSI's you'll probably need a pretty powerful external amp. So of the other guys on the form can give you some good suggestions.

Look into the the Emotive LPA-1 or XPA-5.

Read through the "pure disappointment" thread in this same section. ;-)

Hello, I did the same thing. After much help from folks on here and hopefully them being patient I went with a Rotel RMB-1077.

I saw a member reported hw used an Arcam amp with outstanding results for the LSI bookshelfs, the amp is 70watts a channel of pure clean power. Its about power, not watts per say.

Welcome JoBoy.

Read through this thread for this never ending debate & decide for yourself how much wattage/power/ampres..blah blah blah you want to get.

Whatever you decide to get, think about getting an amp used from Audiogon. You will get more amp for your money that way.

The LSi7's are pretty easy to drive, compared to the other LSi speakers. Before we go whole-hog with upgrading (and I actually hurt when I say that ) could you describe more about why you think your system sounds "weak". This might help us understand better what to recommend.

jo boy I have used Oinkers for many years, they are fine receivers, but if you are running all those speakers off of it, it really cannot supply the 130 watts to each channel at once, in the education section of the website there is an article about this explaining how all watts are not created equally, you might want to give it a look.

There is an acurus 3 channel amp in the flea market now. Under $500 and would move the front stage of your home theater off the 805 and let it just handle the rear 2 channels. Would make a great addition to the LSi's (as some people find the acurus a little on the bright side and the LSi's are a laid back speaker) and should provide some really good synergy.

Your 805 should be fine running your rear speakers.

At this point, Polk should just throw an Outlaw monoblock in with every Lsi speaker...sheesh.

Seems like the dude could stand a decent sub to go along with the 7's.Maybe thats what he means by sounding "weak".Aside from the amp issue of coarse.

Can you describe weak in better terms? Is it not loud enough? Are the sounds not clear? Etc.
