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.


speakers usually seem to make more of a difference than the DAC for me.

IMO speakers, room treatments and EQ account for about 90% of what you hear. I don't sweat the other stuff. 

Hmmmm….. show me YOUR room treatment and I will never argue with you again

I agree that you should get a flat frequency response in your room, mine is posted in my profile if anyone cares to check. There is 35 years worth of published research that listeners prefer a flat frequency response. Do I win a pink panther now? BTW, DSP is very limited in what it can correct and if you want to discuss room treatments we need to start a new thread.


@djones51 your dealer sucked and clearly you did not communicate your needs to them. I will leave you with that or did Amir tell you what to buy?
