never said I was going to change the opamp. just more like wanting to know. like on the do100, SMSL clearly mentions it's using OPA1612x4. I'm guessing the ones on the D-6 are not special?

It'll be similar. Seems to be some TI SoundPlus™ OPA1611/OPA1612. As are most very low distortion output stages nowadays, actually.never said I was going to change the opamp. just more like wanting to know. like on the do100, SMSL clearly mentions it's using OPA1612x4.

We've just kidding. Nobody thought you really want to do this, because with tweaking you could only make it worse and not better.never said I was going to change the opamp.
maybe if you query smsl, they will tell you. or someone can open one up and look...never said I was going to change the opamp. just more like wanting to know. like on the do100, SMSL clearly mentions it's using OPA1612x4. I'm guessing the ones on the D-6 are not special?
Thank you for sharing, what is the difference between pr1, pr0, prd, and how to set up to play music with Bluetooth?D-6 'PrD' is DSD pass through (as per D-6 manual) and this activates DSDD mode of the DAC chip, shown below from AK4493S block diagram.
DSD Direct mode passes the DAC chip DSP (volume control and modulator) and goes straight to switched capacitor filters and through to analogue output.
I actually use HQPlayer to upsample all my music (from hard drive, Qobuz, Apple Music Hi-Res, Spotify) to DSD512 - so all my DSP is done before the D-6.
D-6 just converts DSD direct to analogue.
'All my DSP' includes room correction and headphones EQ', all done in HQPlayer before the DAC.

pr1 is preamplifier mode with volume, pr0 is preamplifier mode with fixed volume set to max, prd is pass-through mode (so no volume at all).what is the difference between pr1, pr0, prd, and how to set up to play music with Bluetooth?
Thanks for your tutorial! The function of the machine is much clearer! I have another question, is the sound quality of pr1 and pr0 the same? Bluetooth play music, which is better, pr1 or prd?pr1 is preamplifier mode with volume, pr0 is preamplifier mode with fixed volume set to max, prd is pass-through mode (so no volume at all).
For bluetooth you need to connect a device ... (e.g. your smartphone), look at the manual of the device how to.
Maybe you should download the manual of the D6 too.
Thank you very much! May I ask if the pcm signal is input to D6, can D6 be set to prd mode?If you don't need to set the volume on the DAC using prd will the best (and most safe, cause no sudden increase of volume due to possible firmware bugs) choice. Using pr1 or pr0 should sound identical at max. volume. When using bluetooth try to set your device to LDAC
thank you very much!I have set prd as common。All my pcm files (16bit, flac) play well in Prd-mode.
does anyone know if the device include a TRS-to-XLR adapter? Thanks
