Arrived yesterday, happy but scared to check it.
Please go to RESET menu and let us know what for firmware version you obtained with the new unit. Pictures on previous pages show how it may look.

I already know the answer. 48k based DSD rates works correctly on fw 1.0 but don't work correctly on 1.21.I am interested to know if 48k based DSD rates work with firmware 1.21 too.
@meowski No other input cable (USB, coax) connected? No change in powering of your system was done, for example on amplifier side?
I would disconnect all input cables including optical and try with bluetooth if the issue persists.
Try to reproduce your issue with battery powered headamp, if you have one available. That would make sure that the issue has no relation to your amplifier.
What are you trying to play via Bluetooth?I tested the unit on a different set of speakers and with a variety of playback devices.
It seems my issue only occurs when using Bluetooth or optical. I tried all setting combinations without success.
However, USB works flawlessly. I guess my unit is partially broken :/
Tried locally stored FLAC and MP3 from Android (with and without LDAC).What are you trying to play via Bluetooth?
So ASIO completely overrides Format options from the XMOS Control Panel according to the playing file's properties
even if 32 bits set in XMOS CC but the file has 16 or 24 bits, it would stream bit-perfect to the DAC chip?
I'm pretty sure my D300 is already using at least one OPA1612A in the stage just before the output. I cracked my unit open to check the resistors, they look like they match when looking at with my eyes, but on camera they don't. All opa have had their tops scrubbed. On one them is the characteristic yellow/tan dot on the 1612A and in the same position. What's crazy is the pictures previously posted have completely different op-amps. SMSL either has different revisions that they don't indicate to consumers or use whatever they can get their hands on. Either way, it's not good. I wonder if they do this in their other models? Though the newer models advertise using opa1612. I think the other two opa in my unit might be TI NE5532D based on the square silkscreen still showing.If the manufacturer erases the marking of the op-amp, it means that he has installed the cheapest op-amp, such as NE5532 or JRC2068.
At best it will be OPA2132...
Therefore, feel free to install all three OPA1612 op-amps and you will be happy!...
...And if you like the imitation of "warm tube sound", then you can put OPA1656.
