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.


please forgive me for stating the obvious:


Anyone can google the part numbers of the parts in the Benchmark (or any amplification) and see what they are exactly, and how they are specified to perform. 


The Mouser or DigiKey descriptions should explain why the designer's choose it.


I do this all the time especially with power-transformers 



@herbreichert : could you please elaborate a bit more on what you said above for those who don't have the patience to google Benchmark parts by part number?

By the way, are you THE Herb Reichert?

latest AKM AK4499EQ chip (2x in my DAC) cost is in-between $100-$200, depending on purchase quantity.

Yes, but that’s not the chip used in the Genelec 8351b that I referenced. The Genelec 8351b uses or at least used, not sure since fire at AKM - AK4621EF.

Not if the misused apostrophe is any indication. The real Mr Reichert is an excellent writer.


Like the Simaudo boys say, it's the stuff around the chip that matter.
