Amplifier's

Ok, I will say right now I don't understand all of this about amplifiers. So looking for some insight. I have Polk RTI-9 speakers that I've read are power hogs. My home theatre and music reciever is a Yamaha RX-A3040 at I believe 140 watts. I have also been reading about Parasound 2250 amp. What would this actually do fo me? If anyone has some knowledge I'd be glad to hear it.

Keep the electrons in your flux capacitor aligned. Obviously.
You'd gain dynamic ability. When that bomb explodes or that kick drum is hit you'll have the required power to properly reproduce it. You'll be less likely damage your tweeters. Mo' betta' sound.afterburnt wrote: »They didn't speak a word of English, they were from South Carolina.

Good point about the electrons. I am starting to get a little worried that I am running out of electrons in my amps since they are on so much. Class A idle is almost like full power in terms of use.Lumin X1 file player, Westminster Labs interconnect cable

I hear ya. I also leave my amp on 24/7 and have been wondering how long I have before it's completely depleted of electrons. There should be some kind of gauge or device to check that.afterburnt wrote: »They didn't speak a word of English, they were from South Carolina.

Bingo.....and how that relates to sound quality has already been stated.
In terms maybe you can understand better.....it's like torque to a car. You can throw any old standard 6 cylinder engine in a Corvette and still drive it daily, get to where you need to go but when you drop a 427 V8 in it, well....I don't need to explain that I hope.
What an amp will also do for you, is give those power hungry speakers what they want so you don't fry tweeters or crossovers. If you've noticed, we have a few people on the forum looking for tweeters from cranking on the volume dial with not enough power or simply driving them beyond their capabilities with an amp in place.
Receivers are adequate by themselves for certain speakers, but not all speakers. Many variables come into play when deciding on adding an amp. Your RTIA 9's though are one of those speakers though that will not perform their best without an amp.HT SYSTEM-

I only use audiophile grade electrons. They're pricey, but they're worth it.
I was thinking about installing a van der Graaf generator to make my own in situ, but that's a pretty big commitment.

In a more serious vein: the interrelationship between amplifier power (= volts x amperes) and loudspeaker load (impedance curve as a function of frequency) is -- interesting. There's a curious admixture of very well-informed opinions and "I read it on the internet, so it must be true" perspective on this (and, indeed, on most) hifi forums, so read carefully. The old timers at an old
forum like this generally know whereof they speak. You'll notice a couple of replies from folks with ca. 25 to 35 kiloposts above.
All this being said, one is well-advised to trust one's ears. Listen to as much stuff as you can, as often and as long as you can. You'll learn what's important, and what works for your ears and tastes. I happen to use loudspeakers that are capable of completely satisfying reproduction of music with a single ended, class A, transformer-coupled vacuum tube power amplifier capable of about 3 watts per channel output -- but that's a special case. Some loudspeakers (ahem, Magneplanars, ahem) may struggle even with a couple of hundred watts (depending on the amplifier).
The best way to learn is to listen. Ears and mind open, both in terms of the music and the opinions proffered.
This has been a public service announcement

The professor in you comes out...lol. The OP is new to this stuff, I like to keep things in terms most can understand because our jargon is like speaking Swahili to them.
Most who ask these same questions will be lost in our terminologies. They walk away just as confused as when they came here. Most the analogies myself and others use are to get points across that most can understand in laymen's terms....without sending new members scrambling for google or wiki.HT SYSTEM-

"Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it.

You won't regret powering your a9 with an amp. Parasound & b&k will open them up nicely.Epson 3020 projector. Da Lite screen. Oppo 103. Yamaha CXA5000. B&K 7250ii. HSU VTF2. Def Tech Supercube 4000. Polk Rtia9 CsiA6 FxiA6. Monster hts 2600. Home theater.

meh electrons come and go with ease, it's the magic smoke you don't want to let out of the amp because once that's gone...it's gone!
a phenomenon well known to fans of (in particular) tiny classic British 2-seat sports cars which featured electronic "systems" (to use the term in its loosest possible sense) by Lucas ("Prince of Darkness").

How long is X banned for?Forever!
Alright I missed something. One of you Yahoo's fill me in please.
To the OP
Remember the movie "Independence Day" the white house explosion scene took something North of 500wpc to reproduce properly. Soon after an amplifier company came out with the "Earthquake" amp that was 600wpc. Then again it's not all about watts you also need a good amount of current to deliver it properly. Most receivers just do not have the proper current to go along with the watts they are listed to have. Then there is the fact that most receivers listed as 140wpc are down to only 60-70wpc with multiple channels driven. The receiver you listed while very nice will never drive more than two channels with anything close to those specs.

ElectronWorld is having a New Year's sale on electrons. You can get a 16 oz bottle for $29.95 while supplies last. -

That's a lot of electrons; such a deal!
I can calculate exactly how many, if anyone's suitably interested.
No, really.

As an industrial electrician working with paint application robots I can verify that this is absolutely 100% correct. Once the smoke is let out that's it, party is over. -
With my Parasound I never run out of electrons. Of course when I referb it I filled the power supply caps with ...

After doing more research I have learned my Yamaha RX-A3040 only puts out 1 volt on the pre outs. WTF? That's to low for most amps.

I have used two different Yamaha AVR's as pre-amps both worked just fine with both my amps.
