Starting to question everything I thought I believed about DACs
I did similar way, using input select button that hdvd800 and stax007tA have. I also use a switch box (all internal part bypass for minimal affect signal)... Or sometimes I compare listening w/o those support, use short memory by manually change the source. With some tracks, I even like the...- TYATYA

Cayin RU6: R-2R USB Dongle DAC with Head-Amp
Today I 1st time curious if Ru6 can produce ultrasonic, example 25kHz properly. Result: not sure it can or cannot (I have no criteria to evaluate). Noise heard clear as you listen to a average dynamic track by a typical headphones at volume lvl 4/100, L gain, 4.4 jack. It should be completely...- TYATYA

Hiby FC6 - another R-2R USB dongle
it's more about recording in pursuit of avoiding affect of low pass filter. Filter doesnt cut off really well at the right Nyquist frequency. To use 44.1 engineers have small margin to cut point, but still not perfection. With 96 or 88 it is ensure to cut after 20Khz and if, any unwant...- TYATYA

Hiby FC6 - another R-2R USB dongle
Do you ever think reverse? Do you heard your device reproduce sounds with many audible flaws? I know the way and do to mine. I do love playing 44.1 what ever the tracks are (88, 96,384...etc) since I audit the noise. 44.1 & dither =the best. I said above, not just relate a cheap dongle(ah not...- TYATYA

Cayin RU6: R-2R USB Dongle DAC with Head-Amp
Heard or not heard the difference depending condition and individual but we may all understand: Relate to noise catching will be amply by a scale so should not use relatively low volume. Relate to output quality (from dap), more volume level got more distortion. Manufactures usually show audio...- TYATYA
