Yammieeeeeeeeeeeeeeee!!!!!

polkyphil38

F1 not sure exactly what you are implying here but my Yammie is pure quality both in terms of power and sound quality. The HTR line is exactly the same as the RX-V but the two are rated differently power wise. As a result, to get the "same power" in the HTR line would be to have a higher power rating due to the fact that the amps are rated at 1,000Hz and NOT across the full bandwidth of 20 Hz to 20,000Hz. They both are made in the same facility and use the same exact parts with the exception of cosmetic differences. Personally, I am more than happy with my yammie RX-V650.

All F1 is saying is there IS a difference in amplifier quality. The Ratings do not tell the entire story. The Yamaha receiver's are not true class A amplifiers, and they are not really designed for high current applications. Not to piss in your corn flakes, but that's just the way it is.

If an amp is rated at one sp. bandwidth, it dosen't get a second glance from me. It's pure marketing BS. Real power will be measured across the full spectrum of audible frequency, i.e. 20 Hz to 20 kHz. On the better quality amplifiers, the range will be even broader, I saw one with an amplification spectrum spanning 1Hz to 60 kHz.

I doubt either of the lines are truly capable of getting your LSi 9's to put out the amount of SPL's you are describing. You must be getting alot of room loading.

Just my .02.

I wasn't even refering to the Yamaha AVR because sound quality and a AVR do not go together as Anthony alluded to.

What I was refering to was this, "I believe a good solution to powering the Lsi9's would be the Outlaw Audio mono-blocks amps. They have them B-stock for $230 plus S&H. At 8ohms 200 watts rms and at 4ohm 300 watts rms. That is more than enough to power a set of Lsi9's and another amp to power the Lsi7's for rears."

You're not going to get "Quality" sound from a cheap amp, period.

Here is another factor about loudspeakers "amulford" even though the Yamaha rate thier speakers at 100 wpc etc does not mean that they are rated at 110 wpc with all channels driven , for example my infinity towers are "power hungry" just like your speakers now I can guarentee that if you put up any power amp against the yamaha's built in amps the Yamaha would run out of steam in an instant. I was a die hard Denon owner before I switched to my yamaha and the 3802 that I had before was good and the Yammy 5790 was a bit better , but when I use to crank those infinitys up "both avrs" ran out of steam but then I picked up a couple of inexpensive power amps and it was a gigantic improvement in sound quality . So even the higher end avrs have the same problem like the Pioneer "Elite" lines and the higher end denons and H/K etc can not and will never be able to compete with separates unless you spend alot more for one like the denon 5805 or the yamaha rxv1 etc, because of the fact of the avrs sharing the same power supply to decode,process,and amplification it has too many tasks to perform and that is why this fact is true.

For the most part I agree (see sony), but that rule falls apart on quite a few high end amps- case in point: VS-1 Reference MK II Hybrid...

Anyhow, with the HTR line, yamaha is trying to compete FINANCIALLY with sony. So they **** the specs a little (and nowhere near as much as sony does), call it 120 watts when it's more like 90 and sell a few more recievers.

As for F1's remark

We're talking about $500-$600 amps here... is there nothing in that price range worth buying? 'cause last time I checked a used rotel has much better THD than a stack of $20 bills.

Lou,

All channels driven and measured power at a specific bandwidth are two different things. Apples and oranges. But if your ratings are measured at, say 1 Khz, chances are your not getting all channels driven, either.

I have a "high end" receiver. One of the few that would drive the LSi's properly. It's great for what it's designed to be. It even does damn good musically. But it's not going to give me the same quality as seperates. I do use it as a pre amp for two channel right now, but I don't expect it to pull out like a dedicated amp will on the big speakers. Just won't do it....

See what I mean???

Jesse,

Outlaw makes great amps, price tag aside. And thats for one channel, not everyone can afford the caliber gear you can.

There are plenty of amps in that price range worth buying...

B&K, Adcom, NAD, AMC, Rotel, Outlaw, Audiosource, Carver...etc

audiobliss

I'm awful proud of my Yamaha receiver, too, but come on; it can't compete with any separates, and it most definitely can't power any LSi speakers worth a flip. (And I believe my RX-V1400 is a little higher up the line than your RX-V650.)

I would say, though, that the Outlaw monoblocks would do a great job for improving power and sound quality for the common man who can't afford the best like someone here can.

polkyphil38

Well I never implied my yammie was better than seperates. And, it appears from this thread it is not going to handle 4 ohm loads as well. No big deal really because I can not afford the Lsi's anyways. However, my yammie will do fine with the Rti6's, Csi5, and the Rti4's that is IF I decide to go with Polk. I am also looking at others including Paradigm, PSB, Ascend Acoustics, and Tyler Acoustics to name a few. If for any reason I do go with the Lsi's someday I will make sure I use seperate amplifiers. Personally, it will IMHO be a good while because my budget is strapped at the moment. But, I have been really impressed with the Rti series especially the Rti6's.

Look, I was trying to raise the bar around here. Just about all anyone recommends around here are the same old B&K, Adcom, NAD, AMC, Rotel, Outlaw, Audiosource, Carver. Granted some of those are good amps, but here's a whole world of other choices, of high quality amps that are affordable on the used market. Expand your horzions people and the great part is it doesn't have to cost a arm and a leg to do so.

Here's one, http://cls.audiogon.com/cgi-bin/cls.pl?ampstran&1125022467

Another, http://cls.audiogon.com/cgi-bin/cls.pl?ampstran&1123952486

And if you go up to the $1000.00 to $1500.00 range the choices really open up.

BTW, my comments were not directed at any one person, just general comments.

Im keeping F1's post above bookmarked for amplifier recommendations.

I know what you mean. That was sorta the plan when I got my Yamaha, but I think it's become a little more permanent than I had planned on. But that's ok, as it does everything I need it to do. And your Yamaha should do a pretty decent job at driving most speakers (including, I think, those you listed).

As for speakers, you definitely listed quite a few very good manufacturers. Just grab one of your favorites CDs you know very well (or DVD, I guess, if you're into movies more), and try and listen to all the speakers you can. Just let your ears (and your wallet, to an extent) guide you.

Good luck, and let us know how it turns out!

I was able to find the audiosource and onkyo amps at ridiculously low prices like the onkyo I was able to find it in a flea market for $60.00 and it goes for $300.00 ,the audiosource I bought new but at less then half the price. Now the reason I wanted to purchase these amps were because I auditioned them before I bought them and then I found them by snooping around and I found them at prices that I was able to handle. So my advice to polkiephil38 is check around save some money and get an amp and you will see a world of enjoyment you never heard before.:D

Excellent Point - I would like to highly recommend Cinepro for those who want something you don't see in everyones setup. Awesome amp and for the price I paid used - incredible value for the dollar.

Now, for pre-amps, anyone have any good recommendations? (new or used)
