Hey, I haven't followed the thread in its entirety, but I've seen that the QNGEE x2 has a low output impedance. Is there a source on this? Also, has anyone done any comparisons with it? I'm particularly interested in this, Shanling M0 and Sansa clips

neutral isn't just flat frequency response. headphones/loudspeakers are mechanical devices that re-creates sound from the movement of a resonating speaker cone. the output sound signal is an approximation of the input electrical signal at best. neutral would mean the input and output waveforms...

 i should rephrase that, since we don't know about all the things we can't measure huh? Quote:

 which is why u didnt answer it? Quote:

well, any amp/dac that aren't misconceived sound the same to me so i spend actually listen to music than my equipment. and as for audio being a ****ty hobby, that depends. i obviously don't get the enjoyment of rainbows and unicorns when listening to uber expensive stuff, but that doesn't mean i...

Quote: when we doing an A/B we are effectively trying to do a null test. we are trying to discard everything we hear that is the same and trying only to tell what's different. it makes sense that our auditory system is a signal processor just like every other component in the chain and adds...

upsampling is standard, but that article is bile...

there may be aspects of hearing we can't measure yet, but we can measure sound. sound is a wave. waves are purely mathematical. unless u think there's a branch of maths that we don't fully understand yet that is required to characterise a wave, u should re-evaluate ur "there may be things we...

Quote: yet people do the same with opamps, and they have published open loop distortion figures. their implementation into the circuit is (should be) extensively measured, so even if it's a cheap opamp to begin with, changing it, even for a more expensive opamp, will probably decrease...

Quote: i agree optical is very useful, but it was not implemented on the ODAC because it comes at an unreasonable cost for providing nothing more than legacy compatibility. 24/192 and balanced offers nothing more than giving u more ways of getting the exact same result.   the point is...

Quote:  can u explain why: 24/192 is better than 24/96 optical is better than USB balanced is better than unbalanced?

 Quote: this not only goes against the principle of hi-fi, but also puts consumers in an unenviable position when manufacturers can get away with peddling anything under the sun for any amount of money. it also creates the illusion that manufacturers are somehow "above" objective design...

thats cuz consumers dont give a ****   Quote:

the facts that were presented were:   1. cables don't introduce distortion. this is true, as an LCR circuit can't.   2. cables multiply distortion. true, but it multiplies everything. it can't differentiate between what's signal and what's distortion. it simply does a frequency dependent...

what credibility? Quote:

and yet Currawong was attempting to objectify these differences. and the hypothesis that "complex music" requires voltages to rise faster is false. you only need to open a music track and a 20kHz sine wave in Audacity to see which voltage rises faster.     i find the subjective position to...

duno where to start   whether any powered component in existence doesn't exceed the maximum slew rate required for audio,   or the fact u think the required rate is dependent on the number of frequencies or density of frequencies present and not the maximum frequency   Quote:

it was a good thread until all of u derailed it SMH

lols in light of the astounding new revelations we have ascertained the cause of bad things is people doin it wrong. hurrah for school!   btw i hope ODAC will be square

so whats wrong with FFT?

what causes time varying noise? hopefully the power stage and op amp PSRR are such that the power isn't the primary source of noise

no i mean Time invariant because if the output is only input dependent then any non linearities will be revealed by testing with the right input signal and u dont have to wait around to see it happen Quote:

im pretty sure amps/dacs can be approximated to be time invariant  Quote:
