It looks like the dB diff between SE and XLR is less than 6.02dB. Does that mean the Vrms change is less than doubled? Since X16 scales well and SE is fixed at 2Vrms at 0dB, can we conclude that output from XLR at 0dB is less than 4Vrms in general or at least in this sample?
I would consider it...
Feed X16 with bitperfect playback from Android APP - Hiby Music (free) and a DAP - lotoo paw 6000. Tested music encoded in DSD/MQA/PCM. All played at native mode.
Couldn't be happier.
Native playback DSD/PCM works with Windows 10 from foobar 2000 except MQA.
Checkout asr DAC review chart. Anything in the green zone and up is transparent. With XLR or pro balanced output is a must. Medium and low price range, you may consider gustard X16 or topping d30 pro(to be released) are talked about recently.
My understanding is that each DAC has its best performance at 0dB with max. rms input. Using digital volume control in player software or DAC itself may be fine mathematically but the DAC performance will degrade during D to A if volume is too low. I am using digital volume control within 10dB...
