Amplifier advice for lsi's please

vodan

I need some help deciding between amplifiers. I have two different systems that I'm needing amps for. One is in my living room and is a 5.1 set up with lsi 25's and an lsi c up front and lsi 9's in back. The other is a dedicated movie room that will have 9.2, consisting of 2 lsi 15's, and 3 lsi 9's across the front, 265 ls in-walls for surrounds, and 500 ls in-ceiling for rear surrounds. In the movie room I have a denon 4311 that I think will handle the four surround channels ok. I'm considering the Emotiva xpa-5 or the xpr-5 for the living room system and for the remaining channels in the movie room. Do you guys think the xpa will do a good job in either or both of these systems or do you think it's worth the extra money to jump up to the xpr?

Thanks in advance for an advice/input

Living Room Amp: You'll need a 5 channel amp that is 4-ohm capable. I run a Sunfire 5-Channel amp, but any quality brand will work. Adcom, Parasound, Rotel, B&K, Emotiva, Outlaw, etc.

Theatre Amp: See above. But with with what you've got in the HT room, well, I'd amplify all 9 channels. And make sure you are running quality subs. I'd go with a pari of powerful sealed subs.

(Wish I had this problem... )

I think the LSi25 is self powered so it will actually take less power than the LSi15, I run an XPA-5 on a 5.1 with LSi15s and I am happy. $770 for that for now.

That said I would sell off the living room set and replace it, with all those speakers I just could not stand having them all be from the same line I would want some variety. And the same goes for the amp, try an ATI amp in one location and the emotiva in the other. Then you may find you like one better than the other or you just might like them differently. The problem most people have is they do not have the luxury to buy and hear more than 1 system at a time =]

Welcome to Club Polk Daniel! Those are two awesome systems you have. Get a couple of the XPA-5s and you should be all set. Or even better look at Outlaw Audio for their http://www.outlawaudio.com/products/7200.html

You should amp as many channels as possible, since you have all LSI's.

Sorry I should have a mentioned, for the home theater I'm going with a pair of HSU VTF15's. The ls in walls are 8 ohm rated and since they're just surround channels I thought I could get by with the 4311's amps. You really think it's best to externally amplify all of them? I've looked at sunfire sig's and outlaw's but they're out of my budget unless I go used but I'm not sure how comfortable I am spending that much money on a ten year old amp..

I've had the lsi 25's and lsi c for quite a while and I don't know why but I've grown really attached to them. I considered doing RTia's in my home theater but I ended up coming back to the lsi's

You don't technically need to amplify any of your speakers, but you seem like a serious HT guy, thus the recommendation to amplify all channels. Yeah, you could get away with running surrounds off of receiver, but I like the surround effects in my face, and the extra power helps to make that magic happen.

You've got a couple OUTSTANDING systems - it will be a pleasure to listen to and I'm sure you will enjoy for years to come.

One more thing - many Polkies here would advocate buying used, either from members here on Polk, or other reputable sites (Audiogon comes to mind). I bought both of my amplifiers used, and while I've had to have one of them repaired (the Sunfire), the repairs were cheap and I got great value for the dollar even after repairs. Just food for thought.

Double Post - thanks iMac.

Well at least do different amps then =]

Thanks for the advice guys

I run Yamaha P series... but you'll need a few to power that many channels... I use mine mainly for 2 channel stuff... absolutely quiet in most situations and powerful...
