@SMSL-Mandy : how is the volume control done ?
analog or digital ?
maybe fully analog with some kind of r2r ladder circuit ?

how can I pre-select the max output level for line output (symmetrical-XLR and unbalanced-cinch(RCA))
if possible at all ?
( I refer to this: -> https://www.audiosciencereview.com/forum/index.php?attachments/qiu_2345-编辑-jpg.366772/ -> "output Level can be selected ...")
The picture is not accurate. You can't switch the output level.
 
I also couldn't find the 4V or 5V switch, and there is no mention of it in their product information. Perhaps this feature was removed before it was released to the market.
Sorry, this design has been cancelled, the artist made the wrong picture and there is no choice of 4v and 5V

Information is currently available on hifi-express.com. That promotional image was done by art designer and was not verified.

Is digital

The number on the decoder shows the current volume, and the volume can be adjusted by means of a knob

Maintain the maximum volume for xlr and rca output

you are kidding with this r2r shit

this is a the cheapest unit in the DL200 AL200 box

its going to be an NJW1194 or equivalent
 
this is the combo DL200 AL200 case so I dont know why they just didnt go XLR on the ESS and AKM variants???
Good question, from specs and pictures DL100 is actually around 25mm less wide than DL200, a bit funny considering that it has more connections and XLR instead of TRS, it indeed appears more crowded in the back.
 
fwiw


its not in english but you get the gist of the unboxing

looks HQ for $175

except the LED display which looks circa 1990

but it does the job
 
The front of the machine looks like a fine matte texture, which I think is very beautiful. In order to fit the standard XLR interface on the back, every inch of space is really used.

Just got one of these in, here some photos including a couple with a ruler to see the size of what amplifier could fit on it. It's indeed smaller than the DL200 so full size amps like the A90 won't fit. There's no high gain mode, just a single one. There's no 4/5 volt switch like was confirmed. Volume control is in decibels (-99 to 0) and not the usual 0-99 on the DL200. It's got a no oversampling filter with the others, I just kept it on the default for now. The plugs on the front are pretty recessed, so thick connectors might have clearance issues. It runs ice cold, even under heavy load for an hour or so. I ran different file formats like DSF (SACD) and it handled them well with the current SMSL driver in Foobar2000. The 4.4mm jack is smooth now, previous models have been pretty scratchy inserting a plug until worn in.

One nice thing is there's no tick/pop when switching bit rates like on the DL200 and D-6s, so speaker people rejoice. All the rest checks out, Bluetooth 5.1 works well, but didn't try the HDMI yet. Coax and Optical is smooth even with a cheap Sybasonic I use to test for functionality. Noise floor is silent when pausing a song with 18 ohm IEMs and turning the volume up to listen for a hiss, nothing to hear. I'll believe the power rating when I see measurements, I remember the DL200 in high gain being a lot more impressive. If I was going to pair this to an amplifier, it would be the Drop SMSL HO150x which would easily fit, and has twice the power. I have an H300 and H400 but doubt those or the A90 are going to fit on it.

It sounds great, and I'm sure this will measure really well. I just don't know why they made it smaller when the XLR plugs on the back are larger than the DL200 with it's 1/4" balanced outputs. One really nice feature is the volume wheel is so far away from the headphone jacks, no chance you'll run into them. The wheel is smooth, but has soft clicks for each DB change. Overall it's really nice, but if you plan to put a full size amp on it, check the ruler measurements I did to make sure it'll fit. It uses the standard RC-8C remote that comes with many of their other things. I'll find an amplifier from inventory to match it up with and take it out for a spin for a day or two if anyone has questions or things to try with it.

Thank you for the info, not switchable gain seemed a bit concerning with the advertised output power, glad to see you didn't hear noise with sensitive iems.
 
What is the difference between DL200 and DL100?
As far as I understand, if you need XLR output and high-power headphone amplifier, then choose DL100. If you think TRS6.35mm balanced output is more suitable for you, then choose DL200. And the headphone amplifier performance of DL200 is not that good.
