When he announced the release of the ODAC, NwAvGuy posted the the following on his blog:
QUOTE
NO SNAKE OIL REQUIRED: Many audiophiles want to believe more elaborate or exotic DACs offer higher fidelity. The ODAC demonstrates you do NOT need any of these for 100% transparent performance:

Asynchronous USB
UAC2 (USB Audio Class 2) Support
Asynchronous Sample Rate Conversion (ASRC),
Minimum Phase Filtering (no pre-ringing)
Non-oversampling NOS DAC chips
Dual DAC chips
Balanced Outputs
Vacuum Tube Stages
Elaborate and/or High Current Power Supplies


Is his position accurate/defensible?

If there was a well-designed DB/ABX test of the ODAC and sub $500/$1000 DAC's (e.g., Audioquest Dragonfly, iFi Micro iDAC, Audioengine D1, Emotiva XDA-2, etc.) that are are Asynchronous, USB Audio Class 2, etc. etc., do you think there would be 'audible/discernible' differences?

The reason that I am asking is that I am curious as to the whether there really is much of an audible difference between various sub $500 or $1,000 DAC's, and I haven't come across any DB tests of DAC's. I have read many subjective reviews that claim differences are quite noticeable. Of course, there are major differences in terms of the types and number of inputs and outputs that a DAC may have, whether they include a headphone amp, how portable they are, etc.

I am not trying to start a fight/flame war, I am just curious as to what the 'prevailing wisdom is' on this site. If you think there are differences in sub $500/$1000 DAC's, what do you believe are the relevant factors (e.g., USB vs Toslink/Coax)? I know that 'speakers' make a difference, but am unsure about how much, if any, difference there is between DAC's. Again, just trying to become an informed consumer (and save $), not trying to start fights.

TIA

PS...I should note that I appreciate people like NwAvGuy and others who try to provide quality products, diy options, etc., at reasonable prices.

Okay, what do you believe is a reasonable price point and what DAC's at that price point do what they are supposed to do w/out adding noise/distortion. Not challenging your statement, just curious. Thanks.


You could start with a $40 Sansa Clip+: play a file through it, record it with some high quality ADC, align and volume match with the original file, and ABX that. I'd be surprised if you were successful.

Personally, I love my O2/ODAC: it matches my needs perfectly, it's fully transparent, and yeah, I enjoy it even more because of my expectation bias. I can recommend it to anyone who can afford it, simply on the grounds that it's convenient, well built (can't say the same about my FiiO E7), compatible with pretty much any headphones and IEMs, it's transparent and sounds great, without comparing it to anything else, without claiming that nothing cheaper could do the job.

Unfortunately the NwAvGuy has lost interest in the audio scene. His last blog was in May (with a few short responses in the summer) and his last visit to another forum was in July.


I have strong suspicions that he is actually quite active on some audio-related forum, under another pseudonym. I won't say who nor where, because I can't think of a good reason to break his anonymity, which he clearly wants to protect. If I'm right though, I haven't the slightest clue as to why he stopped posting on his blog. I dearly miss his insights.
