Can you hear a difference between 2 solid state preamps?

[Evenharmonics]

Pavel can perceive the difference on the 3 very low distortion preamps, however I do not find any of them to be poorly designed.

What does that have to do with results of DBT I mentioned?

It actually is good for you if you can not hear a difference, no incentive to spend on more expensive parts like the AD797. Better yet when you find a cheaper parts like the TL072 to sound the same. Too bad for those who do hear. 😀

Must you attack people so often on forum? 🙄

You lead miles ahead by examples.

......, the subjective version is just that, no level matching, no visual bias controlled, no memory span compensation and no room mode accounted for. The level matched version was done by volt meter at the speaker terminal when amps were switched.

As for Markw4's secret listening test method, will you be asking the same?

I was just asking for the detailed description of your listening tests; if you've never done any serious, rigorous controlled listening test, just say so. 😉

In your biased opinion, of course.

I'm just asking, why do you care?

I am interested in your approach to listening tests.

So that you can devise plans to smear me, a.k.a. damage control, because I'm posting things that can undercut your audio business?

 

[mountainman bob]

Wow.......this was a interesting thread, now it’s the same as the rest!

... I'm posting things that can undercut your audio business?

In my opinion, you are posting things insulting the years of diligent work in improving audio by people like Scott Wurcer, Pavel Macura, Nelson Pass, Earl Geddes and others.

 

[Evenharmonics]

In my opinion,

As I've stated, "In your biased opinion, of course." which you are entitled to. If I post what you are in my opinion, it will get reported to the forum authority so I won't.

Cable lifts! the final step to audiophile nirvana?

I took the two files and loaded them up in Audacity... I was not able to time align them well enough to get a null test showing me the difference. The tempo is off by a tiny bit and the files are different sizes... which might actually be what people heard.

 

[PMA]

I do not think so. They are time aligned with the only difference of different phase responses of the two preamps under test. However, it is their inherent characteristics and is not intended to be equalized by digital post process.

I also appreciate ws2. Impression made on a LS70 iem. WS1 is a bit harsh in treble and has less "body". I also feel WS2 has better details in treble area.
