Powering a FULL set of LSi

549 Views 9 Replies 7 Participants Last post by  tonydeluce
Should I use a Receiver w/additional amp like for the fronts (15's)? I've really got my eye on the Yamaha RX-Z9. Would a full LSi system be properly powered with the Yammy and an amp for the LSi15's I want LSi15 and LSi9 for fronts. The 15's will be up front by the TV triangled to sweet spot. And the LSi9 will be on the sides between sweet spot and TV also fronts. Plus the LSiC center and 2 sets of LSiFX surrounds. How would I properly power all that? Should I do a Yamaha RX-Z9 like I like w/an amp for the fronts or get seperates all the way around? But then what would I do about wanting to have 2 sets of fronts?

Cross that bridge when you come to it.

Get all that stuff setup and then determine whether the Yamaha can go it alone.

Forget about the extra fronts.
Well I'm not sounding like a jerk or anything the extra fronts I just thought of as a spur-of-the-moment thought. But just to kill my own curiosity why not extra fronts? Wouldn't it make it sound more of a 360 degree circle?
Well I've heard nothing but excellent things about Outlaw Audio. So I'm thinking Outlaw Audio 990 preamp & 7700 7-channel 4ohm 300 watt amp. I can get those NIB combo deal for $2,898 and the Yamaha RX-Z9 costs $4,499 NIB. But I'm wondering if I have to a seperate amp for the LSi15 like you do the LSi25. Then I've heard it's better to have a seperate amp for the LSiC center also. I've heard actually having 2 amps a piece for each front. 1 amp for the mids/highs and 1 amp for the woofer. Am I right about everything? What about Outlaw Audio? What about Parasound Halo? I've heard good things about them also. I'm not too worried about price as I'll be doing this along the road after I get the set-up. As long as a preamp isn't $10,000 and one amp be $10,000 and another one and another one. I'm not living in a damn 500,000 mansion or anything, but I want a nice clean processor and nice clean powerful amp. It's not the power so so so much but the most cleanest I can really get without sacrificing a lot of power. I feel the LSi speakers are super tight and super clean so I expect nothing less out of my electronics.

Costs extra money and will muck-up the imaging.

No.

You could dedicate an amplifier for every speaker driver in your system. It'll get very complex and could be very expensive.


You really should set a budget and compile a list of components that'll fit that budget.


This hobby will eat as much money as you care to throw at it and ask for more.

If your going to throw money about, buy room treatments.


In fact, you should treat your room before you spend money on more equipment.

Read the "Audio theory, setup and chat" forum. A lot of things can be done inexpensively and easily.


Expensive gear is cool and all, but the real deal comes from good room acoustics and proper system setup.

I second the above. I wouldn't bother with by amping, just get a decent amp for all channels, and then set it up right.

A) Forget the extra fronts: very dumb idea.


B) The Outlaw route will cost less (if you buy the Yammie from an authorized dealer, gray market could equalize the price a bit) because of the lack of dealer markup. It will offer less features, more power, and more flexibility. You can switch out the processor or amp whenever you like. If you're into lots of bells and whistles and don't mind sinking your dough into something that will get old faster and be harder to unload down the road, go Yammie. Otherwise, go Outlaw. Remember, stuff you buy at a store has the added markup of the store. Someone (you) has to pay to keep the lights on and the nice gentleman that spends his time helping you make your choice. If you don't need help, or are comfortable with the help you receive here, you can bypass that gentleman, and buy direct.


C) Forget the extra fronts: very dumb idea, which bears reiterating.

You can get the BA A7200 (7 x 120w) amp for $750. Which is a steal.


Pair that w/ your Z9 .. Use the BA amp for all the surround & center and use the Z9 for the mains.



BTW If your stuck on the 990 then get two (2) BA amps and bi-amp every speaker w/ 250watts per channel.


Personally I'd get the Z9 over the Outlaw.

The LSi series love power. I just got done installing a new LSi system for my HT...and this is one of the few speaker systems that really heat up my older Aragon/Acurus amps (which generally run very cool under normal operation). In fact, I swapped out my 200x3 with my 8008x3 (which I normally use seperately for other speakers) just because the center channel seems to benefit from the extra juice.


While the 200x3 could keep up, the center channel just seemed to open up a bit more with the Aragons better 4ohm capability. And this would seem to be important since some have complained about the LSiCs presentation in relation to the rest of the system. I've found that as long as you have adequate power to the center that it is a fine performer. These speakers may even under-perform with some 5/7 channel amps depending on how they allocate power for transient spikes. I would definitely suggest seperate amps if you want to run these to their full potential.
I would let the Yamaha power the rears and get a big 3 channel amp for the

LSI15s and the LSic. The Lsi series is very thirsty and needs a lot of current

for them to reach their full potential.
