Thorsten Loesch vs Amir


Let the games begin!

An interesting conversation should be developing concerning the credibility of  the numbers race by the measurement is everything crowd and the rest of us out here in the real world.

 

It's an interesting read so far, the following quote from Loesch in the thread is what I would call as plain as the nose on your face:

“I will not particularly criticise Amir, but I'm looking forward to the day when he finally fixed the groundloops/pin1 problem plaguing his AP2 measurements, something really basic.”

Amir will not address that statement in any credible way since this would be an admission that he is totally incapable of dealing with the intricacies of proper measurement details and would make all of his tests suspect. Even if Loesch's opinion that maybe Amir was dumb enough to have pin 1 connected to the shell of his xlr connectors when he performs a test there is obviously some reason for the constant apologizing for the 'I tried everything I could to get rid of that 60hz crap but couldn't do it.' Not to mention the interference and noise sources common in a residential neighborhood which would negate the chance of any single test results being repeatable.

Now, if you were to choose any amplifier (especially any Class D) test on the site with a favorable sinad value and recommended by Amir the majority of them would show that amp operating within its linear range with a thd+n level approaching -80db or more so often from tests other than sinad Loesch's opinion that performance on a level far, far less than the cult at ASR drool over ( sans any personal experience) is audibly unimpeachable.

The question of equating accuracy of reproduction to measurements will go on forever, no doubt. My question is, will it be answered over at ASR.

If Amir is dumb enough to go up against Loesch what will soon happen is that  Amir will get frustrated and Loesch will be banned from the site.

I was on ASR a while back, just to see what the fuss was about. And I lost interest in the reviews (and the support of its members) in a short amount of time. Bought quite a few top-performing units based on the master table, didn’t like them, sold them. End of story.

I can understand what Amir is trying to do: become a popular/credible source on the internet among audiophiles, audio enthusiasts, and audio professionals. Being "the" faultless" source of information to others who share his interest in audio gear. Furthermore, he went out of his way to purchase costly measurement systems: Audio precision measurement system, speaker measurement rig, and even a headphone measurement rig! Could have spent that money on audio gear!!

Not to bash Amir or ASR, but he has been kicked off/deleted/banned from nearly every audio forum on the internet. Some years ago, this was visible on a bunch of forums (as him being a banned member) but now, I think we can only see his 15k plus posts on Whats Best Forum.

One of which that makes me laugh is him talking about being a subjectivist and "battling" objectivists; then somehow becoming an "objectivist" and going against the grain, in other words: listening and ignoring measurements vs not. There is a nearly infinite number of his posts I’ve read whereby his constant misunderstandings and drivel is enough to make even the most balanced forum members furious.

I think Amir is a reasonable guy, intelligent, yet is investing his time, money, and energy in the wrong places. His community is always quick to mention that a $100 DAC that measures well will sound identical; not volume matching, higher THD levels, and not taking blind tests are the only retorts they can fathom. Rather then, say: audio components "are different’ at the fundamental level, and therefore, will sound different as a result, which they do - it becomes: measurements are everything.

Those measurements don’t include: damping factor, wow, flutter, gang errors (between circuits), side-by-side null testing, using an oscilloscope, input/output sensitivity, testing internal parts, or even an indication/certification of quality control. For this reason, quite a few units that measured well fail prematurely, according to ASRs own members. (that’s what you get when cost-savings was the top priority for manufacturers).

Who is Thorsten Loesch ? is this a well-known person in the audio industry/hobby?

The Musetec Audio (LKS Audio) MH-DA005 has a headless Pink Panther.

The Topping D90SE has a sweet spot Pink Panther.

I recently sold a Topping D90LE (the non-MQA version of S90SE). Thank goodness for ASR because they helped me sell the DAC quickly. It is an OK DAC but to my ears it is not comparable to the Musetec 005. Musetec 005 is comparable to DAC’s like my new Lumin X1. All 3 are ESS DACs

The designer of the 005 posted that he could have made the 005 measure better but then it would not sound the way it does. I have 2 005’s and now selling 1 of them.

@larabee

Can you explain it in context of this:

What is Thorston saying?

  • Is it to not connect pin1 on XRLs
    or
  • Not to connect pin1 to the shell of an RCA?
    or
  • Something else?

 

I think the warning here is to avoid the cult of personality prevalent in consumer audio that is almost completely absent in professional audio. My customers never ask "who" designed a particular speaker. They do ask for particular engineers when it comes to system implementation, integration and tuning, but design? Never.

I don't know why, but I wasted time looking at Thorsten's posts, and some of Amir's replies. I never came across anything on XLR connectors, just one comment about power cables. I did come across Thorsten's strong opinions against ABX while at the same time, I think, putting forth superiority of the ITU methodology. We do extensive formal listening tests so it is something near and dear to my heart. I agree with Thorsten in principle on many areas of testing, differ in some, but also disagree with his fundamental premises on ABX (including that it is discredited, which is not true).

The overall impression I get from both of them is that they are not used to, and certainly do not like being challenged by people who are able to do it effectively and calmly. To me, they both try to browbeat their detractors as a way to avoid addressing the arguments made against their positions. I doubt I would enjoy a spirited discussion with either of them. I am reminded of one of my favorite comedy sketches by George Carlin. I will just say obviously neither of them is stupid, and I don't think either of them is nuts, so that leaves one option.

I am looking to buy a high end DAC.

Does anyone have the link to the manufacturer of the Musetec (LKS) MH-DA005 DAC?
