OK, sorry. It seemed like presenting the FR modification of the Pass amp was an opposite position in the discussion. I've never discounted that fact, though, and recognize it as very real. Also irrelevant in the discussion of soundstage.
Absolutely, speaker response is not supposed to be "flat". It is supposted to be smooth though. Those that are flat, or not smooth, sound terrible in the typical room. Its just important to know which devices in the chain actually change the signal and which to not.
No, no, if you invite me to eat at your house and then serve me spoiled meat, will I feel bad, and is that my fault? I no longer participate, and my stay was short, luckily. I will not make hundreds of contributions again - as happened to me in other forums - only to find out one fine day that they are no more....
Who are "those boys"?
Who deleted their posts?
Why are you so mad?
jaddie ,
Peterbrorsson mentioned Amir....I just replied that the "if you don't like it don't read it" crutch doesn't apply to me. As can be inferred from the story I made, you feel cheated, just that, I'm not angry, just indignant, I'm from the times when codes were respected, (only that, codes, not even the words, that was from the time my grandparents )

most times the proof is by listening not by measurements, so its kind of difficult to discuss the probability of performance over online discussion.
A fact some people can't help themselves from exploiting reflexively, as an antidote to whatever assails them. For thousands of years. Endlessly. In shifts. Many seem to build their lives around this.
Tragic for them, and others too.

Only true of the listening test are done correctly. "I got a new amp and listened" is not done correctly. Listening and measurements should confirm each other, but only if the correct measurements are done.
thats probably best and most ideal, but im more practical.
for example
when i measure frequency response of the speakers i design, i use NCORE and tube amps (300b, 805 and CV391). There's NO variation of the speaker's freq response and yet they sound slightly different for each amp.
note : my speakers have a good behaviour for it's impedance plot because i mainly designed them to be driven by tube amps.
No, no, no... don't get me wrong. I too believe in measurements. I think they are a very important part of our hobby.
But, you know what, I believe that we don't know how to truly measure good sound.
It is all a physics model, and models keep changing as we move along. We really don't know how to properly measure our psycho acoustical reactions. We are getting better, but we're are still far away.
That's why I see measurements only as a start, listening is the second part of the design process.
Flat impedance then?
Quite a mix in there... NCORE and single ended tubes. Awesome, IMHO.
There is no measurable change? Do you A/B quickly or just compare from memory?
I am a fan of listening for days before I commit to a change. I think the mind can overcompensate when expectations are high.
not A/B quickly, but as fast as i could to change....haha.
if its tube, i would give it at least 10-15mins before i assessed them for listening test. i dont do much listening test with ncore except for determining bass tuning.
Regarding what? It's hard for me to understand you, if you're a friend, an acquaintance of Amir or whatever his name is, you guys can enjoy your measurements, and I'll enjoy my perceptions.

It is known that subtle de-correlation between left and right causes wider perception, and this is why inaccurate analog systems offer wider soundstage than more accurate digital ones. Vinyl, analog tape, (some) tube amp offer wider sound stage because of this. When we hear perfectly correlated signal from stereo speakers, we can't tell if the sound is from stereo speakers or mono speaker.
In a small room, the reflections from side walls should impact the stereo widths to some degree, so I would recommend to treat the primary reflection point on the side wall. You can find the point with a toy laser and a mirror. I don't think it would immediately improve the sound stage by itself, but with the combination with the other solution, it may help. The other more aggressive solution is to use M/S processor and add a small amount of delay to the side signal for Haas effect. If you can accept digital effects processors, there are much more solutions, though.
