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.

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

 

i appreciate prof sharing his perspective. the guy is saying over and over that he consciously chooses equipment that "speaks" to him in some way beyond a set of measured specs, and that he doesn’t look at SINAD charts and go "oh yeah that one clearly sounds the best." jokes and differing opinions are all good imho but the way some people have responded to these threads looks like a mirror image of the worst aspects of ASR - the ignorance, lack of reading comprehension, closed-mindedness, tribalism etc.

as for amir i think he’s got an engineer’s brain with a manager’s skill set and he’s been arguing on audio forums for 20 years. thus the certitude, the imperiousness, the unemotional attitude, the hostility towards subjective experiences of any kind, and the (it has to be said) admirable ability to wave away any/everything that challenges his position. this might not be a great set of traits for a scientist, but for a forum poster it’s basically ideal.

anyhow, for my part i’m basically with art dudley on this stuff - there’s no one Correct way to hi-fi, and the people who claim otherwise are just confused

Art Dudley-I miss him too. (I followed his reviews since the 1990s)  There are so many roads to reproducing music. His reviews were generally full of feeling for the music, music that I appreciate.

I more thing about the Benchmark L4 pre-amp. Four of the major reviews (Stereophile, Absolute Sound, Positive Feedback, Soundstage) had the reviewers extol the superior attributes of the unit at the price. However, none of them indicated they would replace the pre-amps they currently use or purchase one. Reviewers often purchase well reviewed products. This unit got outstanding reviews. Nope, no one purchase it. Why? Maybe the sonic flavor was missing (like warmth or body). I don’t know but based on what Mr. Hooper, two friends experiences with their amp & pre-amp, maybe there is a less perfect pre-amp at that price that is more endearing to the music listener.

Topping DAC versus Benchmark DAC-At significantly higher price, the Benchmark is a very superior constructed unit. My modified DAC, despite it’s ordinary parts, has a dual mono balanced design with linear power supply, nice size transformer and very good quality DAC chips. I forgot to mention how fantastically 3-D it sounds. The downside of the DAC is it’s analog volume pot. Sonically lovely, it has a significant channel imbalance when played below 50% level (measured reviews indicate the amount and setting). Benchmark now uses stepped resistor attenuators to alleviate that problem (The L4 uses 40 precision relays and two independent 256-step attenuators, one for the left channel and one for the right channel).

One other point, I only use balanced interconnects from my DAC as the unit was designed that way and sounds best that way.

@td_dayton +1, as for the one right way I can't say about components that is true but what about the room? I think a close to a flat frequency response in the room beats willy nilly, that is a constant. 

 

@sngreen The former forum was closed by the moderator. It got rather snarky at the end and discussion was getting off topic (especially after Amir returned to add his two cents-what his comments are worth here).

@djones51 No, Prof is not Matt Hooper. Mr. Hooper owns and cherishes his Von Schweikert VR5 speakers. Prof has Joseph Audio speakers and never mentioned VS speakers in his extensive speaker review on Audiogon. Prof thinks we are all hallucinating if we hear differences (without measuring or blind testing) and think they are worthwhile. Mr. Hooper speaks for himself.
