amp or preamp most important

so I'm electronically impaired ! Whats more important in the final stage of sound for music and movies, I'm thinking about an anthem p5 325w x 5 and a anthem avm 50, is this going to give me a superb all around 2 channel and home theater, thanks ?
Speakers/room 1st, followed by preamp, then amp. The source would be rght up there with the preamp, IMHO...

I believe amp/speaker matching is most important. Preamp follows after an optimal amp/speaker pairing has been achieved.

Tvad is correct. A bad preamp can screw up the sound but the best one will not make up for the deficiencies of the rest of the system.
The best answer is that everything in the chain matters. I have been listening lately to a $16K amp with $4K speakers and those speakers sound so much better then they do with lesser amps that it can hardly be overstated. (Not that the $ means everything, but I am finding now that there are many rather expensive amplifiers that have qualities that no far less expensive amplifiers can match.)

In general "the preamp is more important that the amp" is one of the larger audio fallacies around. I'm not sure where it came from. It's flat-out untrue for me over the course of trying dozens of preamp/amp combos.
Totally agree with TVAD and it is much easier to screw up an amp purchase than a preamp purchase (for the most part). Having said that, both pale in comparison to the importance of the speaker (and room) in determing the overall sound and quality of your system. If you don't that right and to your liking, no preamp or amp is going to make that big a difference, not compared to the speaker and room.
start at the speakers and work backwards, match speakers to room, amp to speakers, pre to amp and finally get a source that will blend with the overall tonal balance you desire, tweek with wire.

IMO YMMV of course...

so amp first!
I agree with the prevailing opinion so far that the amp is more important.

Having said that, I have some experience with the components you mentioned, and if it were me, I would prefer the Anthem Statement D2 over the Anthem AVM50 for sound quality, and I would be willing to offset the additional expense of the D2 by buying a somewhat lesser amp, namely the Anthem Statement A5, rather than the P5 you mentioned. In my experience, the A5 and P5 sound very similar, though obviously the P5 is considerably more powerful. But if the A5 is powerful enough to meet your needs, I would buy it and use the savings to purchase the D2.

Good luck.
1) Speakers

2) Amp(s)

3) Preamp

4) phono preamp

5) Turntable/arm

6) Cartridge

7) DAC
I agree that the entire chain is important, but in my experience if you get the amp/speaker matchup wrong you are toast.
Amp/speaker matching is most important but do not discount importance of a good pre-amp with proper impedance matching the the amp then as well for best possible sound.
speakers to the room
amp to the speakers
Pre to the amp
add front end and cabling to taste
SAmhar got it right!
How about this? (1)Good source,cabling.(2)Pre amp, cabling to amp.Amp can only amplify that what you feed it .If your speaker is not full range can the full sound one expects be achieved? so I would agree with the speaker first,in todays speaker market I dont see where on a whole the speaker response is of old 20hkz/20kgh(not close w/lettering i know)for speakers. Speaker cabling just as important to get the clear sound.If your pre amp muddles up the sound, your amp can only make it worse.PRE AMP/AMP.A axiom pass/pre Used.its a great sound. Good Luck
How about this? If the amplifier and speakers aren't compatible it won't much matter what precedes them.
PRE-AMP.So, as long as the amp and the speakers are best buds?they can take the just alright music that your pre has sent it and transform it into beautiful music? Your speaker & amp can make that happen? the checking to make sure all components match spec wise is a given.If your speaker is 100 watt max,200 watt amp might not work,But i think the amp can only amplify the signal its fed..Your speakers will let you hear all that mess,as long as your speaker covers the full freg.range
So, as long as your pre-amp is sending along beautiful music, it doesn't matter what happens afterwards?
the gentleman's question was what?IMHO the pre with correct cabling ,given to the amp to bring it to concert levels. Hopefully your speakers can handle the call.You,ll soon know
I guess I should have put I have great speakers that aren't leaving the system, they're rated 150w to 300w per channel, they are ATC monitors they need power and when they get it the sound is truly amazing as I found out yesterday, a guy hooked them up to the ayre v5xe amp and ayre pre, pretty sweet ! So 1 last question guys, he's trying to talk me into a 2 channel for my fronts for music and a 3 channel for my center and rears for home theater, is this good or a waste, thanks for the help !
I do not know what the difference in cost of this versus 5 ch amp. What he is saying may sound a little better but I do not know for sure. I am very familiar with Ayre and this is indeed a nice pre/amp combination. I would imagine that the dealers recommended set up would allow for an easier upgrade path in the future.
I find that 2 channel works fine for home theater for me, but I am not a real HT fanatic.
The absolute reality is, they become one unit as far as the sound is concerned. Imagine a pot of soup, the sound coming out of your speakers is the end result of this soup. The carrots potatos and peas all combine for one single taste. Both units are extremely important.
thanks for all the help guys if you have any experience with the ayre,simaudio,edge,krell or proceed let me know which models and the results !
Thanks Charles
One could argue that a pre-amp is superfluous, but I don't believe the same could be as easily said about amplification.
The speaker/amp combination is the heart and soul of any system.

Get the pairing that rocks you and everything else is downhill.
IMO the heart and soul of a system is the room acoustics and the speaker. Then the speaker and amp.
Bmckenney, that is of course the best answer, but not to the OP question.
Nothing wrong with bringing this up. If every post was totally on topic, it would be boring, and restricted and not very informative.
