Actually the effective noise floor of the Hex is somewhere between -100 and -90 dB but this is still mostly good enough for Redbook and our ears. I suspect you quoted the effective SnR of the core DAC in the circuit, while the fully implemented device as a whole behaves differently.The quantization errors produced by oversampling DACs is very low in level and pushed well above the Nyquist frequency. The analog filtrations designed into some NOS DACs perform necessarily...
Yup, you're right in that regard -- the defeatable NOS switches as used in the PWD and some Peachtree Audio products aren't truly NOS due to the nature of the chip. But conversely, the article you posted earlier is misleading as modern R2R DACs still have a reconstruction filter external of the chip (delta-sigma DACs have this built-in). Since reconstruction filters of NOS DACs is not standardized by any means, the engineer is at liberty to do all kinds of questionable...
Interesting, because NOS DACs introduce aliasing and intermodulation products (sometimes into audible range). My DAC has a NOS filter switch but I generally leave it disengaged. I initially believed it subjectively more pleasing with my HD 800 but I'll have to re-evaluate as it might be "smearing" the sound more than the non-aliasing mode (due to the aforementioned intermodulation and aliasing products).
Any advice for long-term storage? I'm probably not going to be using my SR-Omega for quite a while, so my concerns are functional integrity and preservation of the parts. They'll be in the original paulownia box. So far I can only think of ensuring the pins are shorted out before storage (to prevent long-term parasitic charges) and some desiccant in the box. I want to make sure the foam and pads don't deteriorate either. Not sure why this is so common on the Sigma and...
Strawman argument.Argumentum ad populum + Appeal to authority + Inducive fallacy + Misuse of anecdotal evidence + (possibly) Confirmation bias All ABX/DBT that has not been properly level-matched (preferably with low switching times) can safely be discarded from consideration. As mentioned above, the need for proper A/D conversion is a hefty consideration for investments in studio equipment.
I suspect he meant allusion rather than analogy. The tale is alluded to when suggesting collective ignorance.
In no universe is a non-level-matched experiment "pretty solid." Variance in output levels has one of the largest impacts on perceived sound quality.With sufficient trials by a single individual it would be at least possible to prove the statistical validity for one person (provided the proper controls are in place). To this end level-matching is essential -- among other things like tightly controlled switching times to compensate for echoic memory.
I wouldn't conclude much from the results unless the cans were explicitly level-matched within 0.2dB (e.g. at 1KHz).
Look elsewhere. The TH600 has a midbass hump that obfuscated some of the sub-bass. The older Denons (except the D5000) have their midbass more in-line with the sub-bass.
