Amplifiers amplify

Results are results. Plain and simple. They are all over the place in every test. And the results are always different when they see it.

Yes there are measurable differences. Some like DAMPENING factor are barely measurable. But can we hear them? Does the speaker hide THD?

Measurable vs audible.

but it though SQ was snake oil? the speakers wont hid anything they will produce there own unique distorton

A woofer can cover up how much amplifier THD?

Run distortion test and be real about when you start to hear anything

This is just going to be another stupid discussion about a stale topic and it will produce nothing new. We will still end up with the camp that says they can hear differences and the camp that says "no way man, I read it somewhere that they proved you guys wrong".

It's not just about reading it.

I've swapped plenty of amps. Yeah at first I might think something changed. Normally a power change.

But after really listening to it... Same thing

Statistics don't lie.

yea, and he sure won't believe me. i'm done..

So these two will sound the same the same??Autotek-7300-BTS

Rockford-Fosgate-PBR300X2

opcorn:I am curiuos

With the A'tek limited to 80-90w that the RF can accurately perform at, sure.

I've read discussion after discussion on this topic over the past what -- 15 yrs now...

The one that really got me (besides RC) was the high end home audio crowd that had a room with 8 or 10 different amps and identical speakers. Amps ranged from basic Pioneer/Sony stuff to high end Marantz and other stuff I've never heard of.

They did a listening test where everyone knew what they were listening to and they all wrote down comments.

All the high end amps got rave reviews using such ridiculous language you'd have thought the writer just got laid for the first time.

The more mainstream stuff got some decent comments, but mainly average, like you'd expect.

Then they did the blind test and matched up the comments and in almost no case were they the same, or even similar to the previous comments.

Some of them KNEW they had to be listening to the $1000 amp because it sounded so awesome, but it was the pioneer (or whatever), and vice versa.

In the summary there was the typical list of excuses - listener fatigue blah blah blah.

I know what I need to know.

I just went through swapping and went from a 1400w rms @1 ohm class d massive audio n3 to a 2000w rms @4 ohm US amps class a/b amp. I can most certainly tell a difference. If I run across a cheap amp that'll do 1500+ watts, I'll try and get some audio and do a room eq wizard. I wish I had an oscilloscope, I bet it's a cleaner looking signal as well.

thought you died.I'very yet to hear an amp as clean as lunar or arc competition.

Heard plenty of great sounding systems with a lot of processing but it wasn't natural like the really high end systems I've heard with very little to no processing..

So I guess the power difference don't matter. Or the fact Massive makes junk

Next week you will have a new favorite. What's not natural? Can you explain your feelings

A new favorite? You dont know me or what I've used or heard or anthing realy. So you will just have to find out. I been into car audio for over 15 years and the last 5 or so building my own drivers and designing hi-fi for locals in town..

Have a good day.

See I was in band for about 5 years and played several instruments so the realistic sound of the instrumental when a system reproduces that and you can hear differences like if the trombone is tuned flat. That is accurate sound reproduction.

I have an ear for instruments I've played for years..

All that time and you still have no idea what the real world is and how it works.

 

[n2audio 5,000+ posts]

straight bullshit. 50% get it right which is the same as guessing. laughable. results prove they can hear the differences plan and simple.

didn't do well in statistics huh??

If you flip a coin 10 times and have 10 people choose heads or tails and 5 of them get it right I guess we have 5 coin flip wizards.

People that persue the art of music over the science tend to be the ones arguing for the sound quality of power. I'm glad they do. It keeps the high end amp/cable mfgs in business.

If I could afford that stuff I'd probably buy it too, but not because it sounds better.

if you have 50% that get the majority right id be inclined to say hear some difference. the test ive seen adds external sources and by passes all of the amplifiers internal processing. its apparent any introduced noise will be linear among amps becasue of the external sources used. if you listen to each individual amp with out any processing of bypassing i promise you you will hear a difference. I've done it so many times in my life its not even funny. We have test equipment that can measure the differences. its not magical. seriously.

for example an amp with the 3db noise floor difference is audible. its a fact. Channel separation is harder to hear but poor channel separation is noticeable. evne some components driven to there limits have a unique sound.

im not going to argue and i dont need a artical to tell me what i have experienced.

you buy your budget amp set them under clipping and enjoy. but just remember clipping is a measure of the powersupplya ability to linearly produce enough power not how accurately it reproduces the signal. SHM
