Audio Science Review = Rebuttal and Further Thoughts


@crymeanaudioriver @amir_asr You are sitting there worrying if this or that other useless tweak like a cable makes a sonic difference.

I don’t worry about my equipment unless it fails. I never worry about tweaks or cables. The last time I had to choose a cable was after I purchased my first DAC and transport in 2019.  I auditioned six and chose one, the Synergistic Research Atmosphere X Euphoria. Why would someone with as fulfilling a life as me worry about cables or tweaks and it is in YOUR mind that they are USELESS.

@prof "would it be safe to say you are not an electrical designer or electrical engineer? If so, under what authority do you make the following comment" - concerning creating a high end DAC out of a mediocre DAC.

Well, I have such a DAC, built by a manufacturer of equipment and cables for his and my use. It beat out a $9,000 COS Engineering D1v and $5,000 D2v by a longshot. It is comparable to an $23,000 Meridian Ultradac. Because I tried all the latter three in comparison I say this with some authority, the authority of a recording engineer (me), a manufacturer (friend) and many audiophiles who have heard the same and came to the same conclusion.

Another DAC with excellent design engineer and inferior execution is the Emotiva XDA-2. No new audio board but 7! audiophile quality regulators instead of the computer grade junk inside, similar high end power and filter caps, resistors, etc. to make this into a high end DAC on the very cheap ($400 new plus about the same in added parts).

@russ69 We must be neighbors. I frequented Woodland Hills Audio Center back in the 70s and 80s. I heard several of Arnie’s speakers including a the large Infinity speakers in a home.

I read five reviews of the Benchmark L4.  Uniformly, the reviewers found the pre amp extraordinary in revealing musical and acoustic detail, without any affectation or distortion, in a finely constructed piece of equipment.  Clean and clear was the universal opinion.

It is on ASR, Matt Hooper's review of it and the Conrad Johnson pre-amp Blind Test Results: Benchmark LA4 vs Conrad Johnson Tube Preamp | Audio Science Review (ASR) Forum that I find myself very interested in his keen observations (I used his quote in italics).  The four pages of mostly his observations indicate that despite the super detail, dynamic range and open bandwidth without any negative as to its operation, it is not his favorite to listen to most music and he prefers his Conrad Johnson, with all it's distortion and alterations of the sound.  He prefers a sound with more body and warmth.  Well I prefer my subminiature tube/voltage regulated design pre-amp and I don't prefer the CJ pre-amps or amps I've heard (plenty).  My pre-amp sounds more like an Audio Research SP28 WITH different tubes (6N6 or 6N6).  The stock tubes/unit as is just thin sounding and lacking in the body and warmth department.  I bet it measures better than the CJ and certainly is a more open sound.  With the change in tubes, wow, a totally different pre-amp.

I don't know what is inside of the Benchmark but is reportedly of professional audio quality parts per reviewers.  It may be possible to elevate this to a status which incorporates more body and warmth without losing any of its' measured superior qualities, openness, details and extension.  Changing some caps, regulators and/or resistors.  Or possibly it can't be done and it remains as a finished product with a particular clean, clear sound that is less attractive than other high end pre-amps that may not measure as perfectly.  

So, score 1 for Mr. Hooper whereby he prefers a lesser measuring pre-amp buts enjoys both.   

On the last page, he mentions his love of vinyl.  Score 2 for Mr. Hopper. Immediately, he is warned by a donor member that ASR frowns upon discussion of vinyl records.   Mr. Hooper understands and obliges without pressing the issue.  That's probably why he is still an active member.   Can you imagine if Audiogon members said don't discuss vinyl as a warning, such as that could get one banned from the site?   That's why ASR is so narrow minded.   Don't mention an inferior music delivery format and be careful in your preference for an inferior measuring piece of equipment.   Like there is something amiss not preferring the perfect measuring equipment.   That's where most of the posters here at Audiogon recognize that maybe there are other elements of sound reproduction that are preferred to measured perfection, that are imperfect in some ways.    

Those ASR minions are so silly it makes one want to burst out laughing. I am just reading the thread on vinyl referenced above. What an absolute hoot. Then we get this comment: "Oh, science is right out of the window for this thread." I think there is something seriously wrong with them.; perhaps it is low self esteem. That certainly seems to be the case with Amir, as seen by his responses in other threads.

After reading Prof comments on Audiogon and MattHooper on ASR I would say they are the same person. Seems like a well rounded intelligent fellow who understands the value of measurements but not to the exclusion of what he enjoys. One can like vinyl but understand it doesn't measure as well as digital. You can like tube amps and know they can't measure better than a lot of SS amps. One can understand they are subject to human biases without assuming they are hallucinating, can understand that extraordinary claims that most tweaks advertise should provide extraordinary evidence. 

 

Another pissing contest that will end in the topic being closed.
