So what is this music? And how come practically everyone who tries these tweaks, no matter what their system or music they play, "hears" such improvement?
Why doesn't the manufacture suggest such a music? Or limit the improvement claims to such?
This what Sparkos says about their "discrete" opamps:
"Op amps are a key component for processing and amplifying audio signals. They can be found in virtually all audio gear in the form of tiny integrated circuits (IC's) like the one laying on its back in the picture. They also come with all of the pitfalls and shortcomings that IC op amps have, like limited power dissapation [sic] and crummy compensation capacitors. Discrete op amps do not have these limitations, and are a vastly superior op amp for amplifying audio signals than their IC counterparts are. They can run much higher power, have much deeper class A bias, and deliver a much more realistic and detailed sound. Discrete op amps also permit the use of high quality compensation capacitors, and allow for two pole compensation schemes which are impossible to implement in IC designs. All of this translates into a more detailed and engaging listening experience with better imaging and soundstaging than IC op amps can deliver. In short, discrete designs are the best op amp for audio."
Tell me why they make these general statements I have bolded instead the disclaimers you used.
Ok, in your previous question you asked about how these upgrades can always increase the soundstage.
Need to clarify... the videos and reports on other forums (yes I read a couple taking it all in...) they all talk about going from the standard TI OPA chips to something else... when they try it... its almost always positive. But when they go from lets say a Sparkos or a Burson... the results are mixed. Some say that the other chips don't sound as good or there was a mix of good and bad things. Even the Burson Vivids vs the Classics have different sound characteristics.
I've used soundstage, clarity, presence as examples of what others have said. Sparkos says imaging. I don't know what disclaimers I am making other than saying I'm skeptical and not sure of how valid either extreme is in this argument.
In earlier posts on this thread, I used the term subjective. Meaning that a quantitative number isn't given or available.
I used the example ... he was going fast. Now how fast is fast? I don't know its relative.
What one person experiences will vary from another.
So you test the TI OPA that everyone uses as the default op-amp. ( Price is a factor)
Did you test it against a Sparkos? I saw Sonic Imagery...
And again, when i talked about a change in sound stage, you said it would have to have some measurable change in the signal. Ok, so where would we see this?
And how much of a change would be required to be noticable? And how would you test for it? I don't know which is why I am asking.
And that's my point in all of this...
On the one hand I hear tons of people talking about the impact of rolling op amps.
Are they *all* delusional?
Which is why I am asking you... who does measurements... what are we not seeing?
In my analogy, I tried to point out that while you're doing tests and they show one thing... is there another test that would show more information?
Thx
