Cleanest Amplifier

[DrewRafter]

Allright then, pick one between these two, I've narrowed my search between the MTX 801D and the Polk C500.1. Which one would you rather have and why?

i didnt say that i knew what they were. i just laughed when zane made the claim that amplifiers cannot affect sq. thats just not true.

Go ahead then. Prove me wrong.

If an amplifier does anything other than strengthen the signal, it's either not an amp, or it's broke.

Yes, let's let ignorance talk and play the THD card too.

Amps today are all below 1% THD - which is arguablyIn-audible!

I can't honestly believe that this non-sense of amplifiers effecting SQ is still an issue.

BTW- what part of the amp makes the SQ?

it's the magic dust, jeez I thought everyone knew that.

No, only Josh uses the pixie dust to make his amps sound better.

I personally feed my amps taco's for nourishment to make the sound stronger!

I agree with zane.

The cleanest amp I could find was at best buy. The guy was actually polishing it, it was very clean. No dust, no scratches. I could almost see myself in it (and it was "matte"). One time I saw a real clean amp in a car, then some dust fell on it...

Oh, and by the way....

Ya know how vinyl stickers give you more hp?

Guess what metallic stickers give you on an amp? I've seen (with my own eyes) lower THD by 95%, a 20% increase in RMS AND actual stickers being used as SSF's! Seriously, what's in those stickers...?

what about the difference between AB amps and Class D amps? Where the signal is converted from analong to digital long the chain doesnt matter? And what about DB per octive crossovers? Like the new kicker SX amps have 36db per octive crossovers, and that wouldnt sound cleaner than a pyramid amp trying to cut off unwanted frequencies at 12db per octive?

the price tag, man...

honestly though, a pure class B amp.. aren't those notorious for sounding horrible?

any THD over 2% would be audible to any of us, 75% would be ridiculous

Disregarding Pyramid and the like - there isn't an amp on the market (other than class D) that has a higher THD than, what? 0.1% at rated power - which is at least 10x, some say as high as 30x less than audible distortion. THD isn't worth concerning yourself with.

...a S/N ratio of 90, versus a S/N ratio of 110 is a huge difference, 20 DB is a lot.

That's just not true. Engineers in the field routinely claim that S/N is only a factor if it's below 40 or 50 - which we all know every amp is well above.

It's all relative. Think of it this way, using your example of an amp with a 90 S/n vs. a 110S/n - both amps producing 100dB of music. The amp with 110 S/N will have .91Db of noise while the amp with 90 s/n will have 1.11db. How "huge" of a difference is that?

Most everyone here understands that you generally get what you pay for - but with amps - you're NOT paying for SQ.

any THD over 2% would be audible to any of us, 75% would be ridiculous, not barely noticable and a S/N ratio of 90, versus a S/N ratio of 110 is a huge difference, 20 DB is a lot.

Heh...you wouldn't be able to hear a 5% THD unless you were in an anechoic chamber listening to pure test tones //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
And a quick sweep of Etronics shows no Pyramid amp with a THD more than 0.2%...

And do you know what a signal/noise ratio is? If you do, I'm sure that you also know that it's expressed as dB (that is, 10 times the logarithm of the power ratio).

Sit in your car where ambient noise is 50 dB. Now play music at 140 dB (90 dB). Let me know if you hear anything but the music //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

BTW, if 20 dB is a big difference, then you just told me that JBL (90 dB) is better than Xtant (110 dB) //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

I wish I was cool enough to have a SQ amp! But until i get much dinero to buy a mcintosh or zapco or something of the likes i will have to stick with my "SHITTY" Rockford fosgate Power 1050s BTW why is my amp so shitty anyway? I always here PPL say how RF is shitty now days but no one can tell me why...Is it the fact my amp is underratted by more than 200wrms(birth sheet to prove it) or the fact the S/N is only 100 db or the THD is

 

[b0mbrman 10+ year member]

I think the general consensus isn't that RF amps are bad; just that they're not worth the inflated retail price.

I can totally understand that and had i not gotten mine for 300 bucks i would have never bought it. However i have had people tell me that they just ****! More than a few times! I dont understand it.... I think for the 300 i spent i got a pretty **** good amp! Would that be a false statement?

 

[somekook 10+ year member]

ok guys, if youre going to argue with me, refute what i said. most of you are making irrelevant points. all i said was that amplifiers do affect the signal somewhat, i didnt say there was a large audible difference, or even an audible difference at all.
