Isn't this a function of the word length (bit depth or resolution) of the digital volume control? So that e.g., if the music were recorded using a 192 khz sampling rate and a 24 bit sample size and the digital volume control uses and 32 bit word length, then there will be no reduction in resolution when volume is < 100%. Does anyone know if the Oppo volume control is analog or digital; and if it is digital, its resolution?
Just trying to help with the Volume issues of lost resolution etc etc on lets say the Oppo player.....I found this on the
Remember I'm no expert and really have not figured out this Digital-vs Analog Volume Control Issue, about "lowering the Resolution" output! But as Skylab said and I agree, to me it only stands to reason to keep the source's vol.at 100%......Here's what OPPO says................Item 5)
- Improved volume control function for the analog audio output. Volume control was previously implemented using the DSP (Digital Signal Processor). This version utilizes the DAC (Digital to Analog Converter) chips to perform volume control. This change brings the following benefits:
- Fix for the sub woofer hum that happens when the player's volume is set to less than 100 while outputting SACD in DSD format over HDMI;
- Volume control in DSD mode for SACD. Previously volume control does not work for DSD mode. With this version, all analog audio outputs of the BDP-83SE and the dedicated stereo output of the BDP-83 can apply volume control in DSD mode. (Note: OPPO recommends setting the player's volume at 100 and using the volume control of your amplifier or receiver.)
I'd love to read more from anyone on this Vol.Control Issue..... Even if this question/answer needs to be moved to a different post..........
