Amplifiers can you hear a diffrence?

I can give you an answer, I cannot give you an understanding. If you can't be bothered with a 5 minute read, clearly this is not important to you.

Correct, not worth 5 minutes.

I've trained my wife to keep emails to one line, one sentence. That's my attention span for pure communication purposes, but I listen to her talking for hours.
 
I have one for you..

Her: "What is that robe doing at the floor of the bathroom?"
Him: "Honey, I just struck a Jedi!"
Her: "#%&!!$#&%"
Him: "Yes.. yes.. use your anger!"

Chances that this conversation will end up in her throwing her skirt on the floor are pretty much the same as they would be if you use SIY's method. :D

I have one for you as well:

Bull and Lion went to a pub one night, and after several hours of drinking and chatting about cars and sports Bull's cell phone rings.
"What?", he answers the phone.
"I dont now when I will be back, why the f*ck are you even asking?"
"Never bother me again!", and he closes the phone.
"Who was that?" asks the Lion.
"Ahh, my stupid wife, I still need to train her", replies Bull.
After few minutes Lion's phone starts ringing.
"Hello my dear. No, no, I'm not with girls, you are the only girl I need. I'm sitting in the pub with Bull, you know, drinking beer, chatting about car and sports, men's stuff. When I will be home? Well I guess I can make it in 15 minutes. Sure honey, I love you too.".
Bull, knocked off his chair from surpise starts his tirade: "What the f*ck?! What was that?! You are the King of all beasts and look at you! Was that your wife? Can't you train her better?!? Didn't you hear how I talked with my wife???"
"I did, M8, I surely heard. But keep in my mind that your wife is cow and mine is lioness". ;)

Allright that was a good joke.
Anymore .....
 
Not jokes but recommendations?

I still think you would be better with 150w+, whether Serge's Behringer Class D studio amp and a Bluesound Node 2i, there is an Onkyo TX-8390 that is more powerful and my recommendation remains the Quad QSP and Node 2i because I've used both, many thousands have used Quad with Harbeth over 30+ years, the speaker was designed with them and you don't need measurements to make that decision.

That said, when the original Quad solid state 33/303 amplifier was issued in the late 1960s and reviews were usually measured tests by professional audio engineers, the reviewer had to go out and buy more accurate testing equipment at very considerable expense. The QSP technology was first issued in 1983 and was designed to be highly accurate with very cheap components.

On the money side, if you buy a Yamaha or Onkyo for €500, how much will it be worth in 3 years? €100? Like your Harbeth, Quad can be viewed as a long term investment, people keep them for 30+ years, and a used one will hold its value. I owned three and sold them all for what I paid.

There is unlikely to be much love here for Quad amplifiers because you won't find anyone doing measurements and no one is likely to send one to ASR to measure. So for ASR it might as well not exist. It is ironic because Quad was always about top measured performance.
 
+1 for Behringer A800.
 
I am indeed another fan of the Quad 606-2/909/QSP/Artera series. I forgot to look where you are, however, because availability can be an issue in some markets. But with proper maintenance they will last you a life time. And even in the unlikely case if Quad themselves go under, replacement parts will not be a problem.
 
Well, one of the most important tests for amplifiers is amount of power versus distortion. You absolutely will hear amplifier running out of power.

Agreed but thats at an extrreme. Lets talk about two amps running well within their power envelope, outputs level matched through the same speakers located in the same room and in the same listener position. Toss in a blind fold for fun to eliminate all sight bias and then conduct the test. I'm betting most if not all people will fail to distinguish between the different amps.
 
Not jokes but recommendations?

I recommendation you use an amp that adequately drives your next pair of speakers, which will be purchased with the money you save from not wasting $$ on a 'magic' amp.

Further, pay no attention to people who don't understand electronics or science in general.
 
What confuses me is @March Audio with claims of hearing differences between the hypex modules and the new purfi designs.

That puts a big question mark on the idea of what amps might be ' transparent ' .

So assuming he's right , what are these objective measurable phenomenon that break and go beyond psychoacoustic thresholds to produce such a observable difference?
 
It's because not a single amp is really transparent.

I'm not sure we should believe what vendor is saying about amps.. :P

I have extremely high regard for @March Audio (which is no secret) and I'd be happy to use his amps. But... his support for that claim has not been very strong, and I think it's likely that this isn't right.
