gday. i would just like to know if there are members who have any experience with smsl audio gears? its my first time to post so please feel free to transfer my inquiry to the appropriate thread. thanks.

I am using SMSL SD-1955 DAC. Bought this more than 3 years ago in Huaqiang Bei.
This DAC uses the Analog Devices AD1955 digital to analog multibit delta sigma IC.
The DAC in unmodified configuration sounds good but with some modifications - heatsink on AD1955 D/A IC, output op-amp change and power supply change sounds fantastic.

I have the M8. Good DAC! Love the ESS, super smooth and great for recordings that sound harsh on other sources.
What I don't like about SMSL is how the amps are over-marketed.
Take the SA-98SE, for instance. A lot of online literature rates it at 98W, sometimes even 120W or 160W, but it's actual wattage is more in the 30-35W range if you want to stay within acceptable limits (1% THD).
From their spec page (https://www.shenzhenaudio.com/smsl-sa-98e-160wpc-tda7498e-class-t-digital-amplifier-power-adapter.html):
Output power: ( DC=32V )
80W/ 6 ΩTHD = 10%;
65W/ 8 ΩTHD = 10%;
65W into 8 Ω @ 10%! I can't see anyone in their right mind who will listen at 10% THD. The clipping would destroy your tweeters! And yet SMSL recommends pushing it as far as 160W. IMO that's just marketing being retarded. Just be honest and say it's a 30-35W amp:
Use the power adapter for DC32V SA-98E. Pick6Ω80W power ( THD = 10% ), then 4Ω100W power ( THD = 12% ), power amplifier distortion is with the power increase and increase. So we mark ideal listening to 120W/ power per channel.
This over-rating of the power output seems to apply across the board to all Chinese-made T-amps. The Lepai "20W" is also at 10% THD, in actual use it's good for 10W at most.
-
These SMSL amps use an external power supply. Best to just look at the power supply specification. If power supply says output power is 50W then the most the amp can deliver is 25W per channel (assuming 100% efficiency).

i was hoping to have a desktop setup using a senn hd600 as hp. i have read/seen some of the reviews on the smsl vmv va2 but there is the vmv va1 hd which is tuned specifically for the senn hd600/650 and the vmv v2. i was just wondering if anyone has experienced these units or better recommendations. thanks.
-
got a question for users of M8. im hooking mine to my laptop thru usb and then after a while theres a buzzing/humming sound on the unit with the message in the screen that theres no signal.
anyone experiencing this? what seems to be the problem and how to go about it

Anyone know where I can get a new SMSL power adapter or have it repaired?

I'm in the same situation. Power supply died after a power outage. I ordered a generic power supply on Shopee for 400 Pesos, fingers crossed.

Let me know sir if it works and what kind you ordered. Salamat

as long as the Voltage & Head is the same those replacements can work. Also the get one that's the same Amperage or higher, also check the max Voltage of your smsl as some vary from 12V~32Volts depending on it's output.
I bet there are guys her who have those PS just lying around the house ;)

i was about to ask about the amperage as most of what's on sale at Lazada or Shopee are different. Either lower or higher
-
the higher Amps would be better as it will have more reserve to push those output BUT never go beyond the maximum rated Voltage like say 12V~32V @ 5Amps
pag sobrang low naman yung current(ampere) mo there's a tendency to overheat the supply if you push the amps to it's upper limit as it tries to draw more power. A good PSU is vital for your SMSL - low noise, high out put.

I ordered 5 amperes. Same voltage 24 V.

I received the power supply from Shoppee today, it was 404 Pesos. It only took one week! It works, the only downside is the electrical cable length is not that long.

I used the Shoppee app, I'll try to look for a way to post the link.

salamat bro, at least verified na ito to work with SMSL

Got mine after a week, verified to work with SMSL Amp. Thanks Conan

any other user po?
gagamitin ko sana tube + FR speaker..
wala ako mahanap na similar feature tulad nito.
any suggestions? ty
mas mura din kay shopee...(https://uploads.tapatalk-cdn.com/20190118/5e358ebc5f931a55b17ca1d6ddbe90cb.jpg)(https://uploads.tapatalk-cdn.com/20190118/e18c7d0b94f9fe66b39db3634cfe452e.jpg)
