Lamp cord?

I've tried lamp cord and was actually quite surprised.

This thread is like watching a group of scientists try to explain quantum physics to primitive cavemen

[PeterSt]

but the scientists didn't turn up.

Amplifier, Preamp, source and cable should not impart any coloration of their own

 

The operative words here are should not.   In practice, it is an entirely different matter .

My observed results are that CPU load under 50% doesn't  degrade what I hear with the caveat that I don't use/like oversampling/PCM to DSD conversion.

And that given two like computers playing complex music pieces, the computer with the faster CPU will resolve better even if CPU usage is approximately the same.

 

 Agreed, but the usual suspects will refuse to accept that this is possible.

 Have you also ever tried running a full Security scan at the same time on a Computer with a slower CPU and noticed any SQ degradation.?

 I certainly have on a Windows XP and Windows 7 PC.

Why don't you start a Poll on this subject ?

So you have no idea about it but relies on polls?

by definition a security scan uses significant system resource and lots of hard drive activity. Neither of these is good for music playback in any OS

Why? Any evidence?  

[davide256]

BTW Windows is a poor choice for a networked solution, easily goes into “mumble mode” if the network misbehaves. And readily develops memory leaks

 I was attempting to humorously suggest that you do this to show you what a silly statement you had made.

 Almost all Amplifier, Preamps, sources and quite often cables, impart some degree of degradation or coloration of their own .

 Are you by any chance related to either Ralf11, Marce or Mansr ?

 

Audiophiles do not normally have the background knowledge or test equipment needed to take such measurements and the Objective members here refuse to accept the results of correctly performed DBT sessions.

This is the job of qualified members in that field !!!

Yes. But do you have the evidence?  Or is there a reason for you to believe a 100W amplifier Amplifier to sound a like the 100W Bryston?  Both are 100W, right?

Probably, my great great great x n and his great great great x n originated from Africa. I am not sure about you.

 This is getting ridiculous . I

f you can't hear, say the difference between a 100W Class A amplifier from Nelson Pass, a typical not too expensive 100W Class D

amplifier, and a 100W Vacuum tube amplifier then you have major problems with the rest of your system.

I can make both Amp to sound alike or even could make Nelson Pass to sound worse than the cheap 100W. So now how do tell which one is really a better amp. Still by listening only?

[STC]

Why @Teresa why? At least say why you are disagreeing. You don’t believe I can make the Bryston or Nelson to sound inferior to the cheap Amp by subjective listening?  What is the conclusive evidence that would show these two amplifiers better than the cheap amp.

Because it sounds like complete nonsense to me. Such an extraordinary claim would need ironclad  proof.

 

Bob Carver with internal component changes was able to make his amp sound like a highly regarded tubed one. Carver equipment is not cheap, though. And redesigning an amp to sound like another would not satisfy your bizarre claim.

 Let's hope that you don't do that for the owners of the amplifiers that you repair !

I’m sure that you can make any amp sound worse 😝

Does the possibility exist that this kindergarten changes into a biergarten again ?

Unbelievable that you guys find it so hard to admit that measurements should show which is a better amp or not.  Trying so hard  NOT to say the word.
 

Measurements determine what is good bad. 
 

Once your reach the threshold of human hearing than whatever subjective opinion that you make is subjective and cannot be proven.

 

IF YOU WALK IN TO A ROOM BLINDFOLDED and unable to confidently guess the speaker, cable, amp, source than you are wasting your time chasing the minute difference.

I will say the word for you  -

 Bullshit!

Current measurements can only suggest a possibility as to how a component may sound
