system

you're talking a goodly amount of money there....

you have ask yourself.

1. how much will I be using this for home theater and how much for CD/music listening?

2. budget - this is what determines what a lot of people do with.

3. taste in sound - here again... the skys the limit in terms of how much you can spend to get the sound you want.

finally... those Polk Audio speaker are the top of the line LSi speakers... they are not cheap.

at first look... it appears the guy does have some knowledge of gear. but is this HIS dream system.. or yours?

i would proceed with caution.

I think the weakest link in the equipment you mentioned is the Yamaha, for two reasons....

1) Not powerful enough to run the LSi's with the type of power they need. The LSi's, as 90% of the forum will indicate, need seperates to really come alive. I scanned Yamaha's site and they don't even list any 4ohm ratings for their stuff, so I don't know what power you're going to be getting them. Also, some have gotten away with running the LSi 9's and 7's off a receiver, but IMO the 15's are too much speaker alone, let alone with the C and inwalls in the mix.

2) Many people feel that Yamaha receivers are pretty bright sounding, and that might be a source of concern. Before you go and drop the serious coin that you're going to on that setup, I'd make sure you get the speakers on the receiver you're looking at to see if you even like the sound. True, there is a break-in factor on the speakers, but you have to at least see what you're starting with at the receiver end.

I agree with brettw22. The yamaha rx-v2400 owners manual specifies a minimum speaker impedance of only 6 or 8 ohms. The LSi speakers are 4 ohms, the receiver is not designed to drive speakers of this low impedance (and may void the warrantee).

Better, but what you're asking a receiver to do with those speakers is NOT going to be a good thing for the life of the receiver.

In all honesty, if you're budget is strapped with the stuff you outlined in your initial post, I'd consider going with the RTi line. Those won't have any problems being run off of a receiver, and you will be in much better shape as for protecting your investment.....

My LSi7's have always had a seperate amp pushing them, but as of today I can attest that the LSi's are nothing without good power.

I'm visiting my folks in Phoenix, and stopped by the Tweeter (Home Theater Showcase) in nearby Chandler. One room had a Denon 2200 hooked up to a B&K amp going to LSi25's... unfortunately the 6CH analog cables weren't hooked up so we had to go to the other room.

Let's just say it should be a crime to drive LSi15's with a Sony AVR. I think the guy realized the problem when I asked him to turn it off after about 15 seconds of DSOTM SACD. Absolutely no bass coming out of them, and they were clipping at -25 from ref. Just hope he didn't damage the poor things. I wanted to grab them up and rush them out of the store like they were children in an abusive household :mad:

Unfortunately that was the only reciever/amp close enough to the SACD player to hook up. What a shame, I really wanted to hear some SACD on LSi's before I plunk down $500 for a Denon universal player.
