New S.M.S.L. M300 SE 120$

Smsl M300se
Just received yesterday.
First impressions are very positive.
As a headphone amplifier, unfortunately, it is of no interest, but as a DAC it is very, very good.
One of these days I will connect to a good PSU, then I will write a test.

Can you use it as a pre amp???

Can you use it as a pre amp???

"At this time the pre-amp mode is OFF". So likely...no?

"At this time the pre-amp mode is OFF". So likely...no?

"You can select preamp mode turn on or turn off"

"At this time (=in the picture), the preamp is turned off", hence the display reads FIXED

So yes, the M300se can be used as preamp.

I picked up a used SMSL M300 because my new Topping D10 Balanced kept making popping noises. Imagine my surprise when I install the M300 driver and it is the same drive as the Topping D10. I should have figured.

Anyway, I noticed when restarting my laptop the M300 makes a bunch of random noises and pops. Going to need to rewire my USB and see if that helps.

The whole point of this was getting a cheap balanced DAC for my work from home setup. My single ended D10 original makes ZERO clicking or popping noises. It just plays music like it should.

Hello! I would like to know if the SMSL M300SE is detected by a phone's bluetooth connection, if the SMML input is set to optical.
Thanks in advance!

What exactly do you mean? What is SMML input?

In general, and this also applies to the M300SE, Bluetooth is only activated on DACs if Bluetooth is explicitly selected as an input. In all other cases, Bluetooth is deactivated and cannot establish a connection.

Thanks for the bluetooth information( A friend has bought the SMSL PS200 and that one has an input selector, but the PS200 is always seen by his phone's bluetooth network, regardless of the selected input...),
Another question: can you use the balanced and unbalanced output at the same time.?

Another question: can you use the balanced and unbalanced output at the same time.?

Yes. I can confirm that both outputs (XLR/3.5mm) at the back are active simultaneously. Do set outputs to ALL in the menu.

Amazon has "Upgraded" version of M300SE listed, don't know if it has the bugs fixed that were discussed in this thread though.

This upgraded version was listed after just a few months, so at least a year or more ago.

Thank you for your information. Do you have the SMLS M300SE or do you know for sure that you can connect to the DAC only when Bluetooth is selected as an input?
It is very important to me to know for sure.(because in the SMSL-P200 , you can connect a phone and the DAC with bluetooth even if the input is selected as optical-and you do not change that-, which means the bluetooth is always active...)

I have one of these units and the Bluetooth connection only activates when BT is the selected input.

Obviously, this may not be true on all possible hard/soft variants of the M300, but that's how it is on mine.

Thanks a lot. I will buy one.

Just received mine.I have it connected to HS8 monitors with XLR cables and HD650 with balanced cable.I have noted a small problem, a low volume *thud* emanates from the speakers when the DAC is turned on.It also happens when I switch output between All/HP/Line, and when I mute/unmute.This happens only with the monitors and not with the headphones.The SE line out is quite too.

I have it connected to Laptop running windows.The HS8 monitors run fine with my other audio gear.Anyone experience similar problem?

Very common issue with DACs like the M300se.

Removing these power on/unmute pops requires special care during development which brands like SMSL and Topping don't really see the merit in.

The only thing that may help is this: https://www.audiosciencereview.com/...os-driver-settings-for-no-cutoff-delay.25838/

Thanks @staticV3.Did try the above method, I am unable to save the XML file ( not a computer guy ).I will get it done later.

Will this in any way effect the speakers?

Thanks @staticV3.Did try the above method

I don't have an XMOS DAC currently, so the driver panel likely wouldn't even launch

Will this in any way effect the speakers?

The only effect would be minimizing pops and clicks.

Thanks for helping me. I disconnected the DAC from all signal sources, from sound sources. Disconnected from Wiim pro. Disconnected from the computer. Just a naked DAC. Only the DAC itself without anything. DAC power only. I supplied 5 volts to the DAC. First from a switching power supply. Then I tried to apply from a power bank. I connected a multimeter to the RCA outputs. When the DAC was turned on, when switching inputs on the DAC, the multimeter showed DC voltage surges at the RCA outputs. on one channel 3 volts, on the other channel 3.3 volts. If you connect acoustics through an amplifier, these bursts produce pops in the speakers. 2 claps. Almost simultaneously. These pops and DC bursts are always going on. Regardless of whether there is a source of signal, sound, or no signal. But I'll try the headphones tomorrow.The DAC is definitely the source of the pops. Without a doubt.I tried everything you wrote. Except for the headphone test.I think I got a bad deal! Defective item.

Now, how did I miss this post?!!.Did the same test with both balanced and RCA output, you get 3 volt DC with both.Apparently, the balanced headphone output shows no DC voltage.Shame on SMSL for selling this product.
