I daresay USB>DA100 is as good as SB3>DA100, so the DA100 is a good first purchase. I've yet to do some critical listening with this, although the selector switch will make A/Bing quite easy.

Update on the hum issue. Thomas from April Music has been emailing me about this problem. He sent me a picture, and suggested that I remove some screws from the AC socket and lift the PCB from the ground, whatever that means. I'm skeptical about it because lifting the entire ground with a cheater plug didn't work. I'll give it a shot anyway after work. Here's the picture he sent me:

Sigh.

I took the DA100 to a friend's house a few miles away and plugged it into his hi-fi system. No digital source was connected to the DA100. The hum started like it did at my flat.

At first I suspected that the AC power at my flat was causing the problem, but now I'm convinced that my unit is faulty. April Music have been amazing so far in dealing with this problem, so I hope we can sort out an exchange without me losing out on shipping and duty.

I am surprised to see it has more refined and extended trebles suddenly. 3D imaging too improved now. I am very happy with this jewel and will not upgrade for some time.

Approximately how many hours of use/burn-in has it been?

About 130-140 hours!

First Impressions from EMU1212M User

Just got mine last night, configuration:

Foobar > ASIO > 1212M > (Coax) DA100, (Analog, +4db) > MF A3

I listen to pop / acoustics.

Some observations:

1. 1212M has more 'details' in +4db mode, but this might be what some call 'harsh'; I was actually disappointed with this result (given the price). You may say it's not volume matched, but I wish I could easily make DA100 louder. With DA100 the vocal seems blended with the music
2. At -10db, DA100 shows more detail; bass from 1212M is a bit blurred by comparison
3. A problem that occurs occasionally but getting more frequent now is that I hear noticeable dropouts. At first I thought it's the source material, but it also happens when I use my scanner - now it happens even when the machine is idle. I might try USB later.
4. The unit is hot! There is also a big thud when I switch it off - is it supposed to be on all the time?

Appreciate it if somebody can help me with the SQ and the dropouts

1. If your ears are used to a brighter and harsher sound then maybe you have to "burn in" your ears for DA100. Listen to it some time and maybe you'll start to appreciate its sound. It's also possible that you simply like 1212M better.

3. I've never had any dropouts with mine.

4. Yes the unit runs very hot but it's normal.

Congratulations! Turn the volume on your amp all the way down before turning the DAC off, that's what I do.

No dropouts on mine, just the confounding hum issue. I'm going to exchange it (hopefully) next week, otherwise it'll be a refund and I'll get an Opera.

Yes It runs very hot due to discrete class A output buffer. Stello advises not to cover ventilation holes in the DAC to avoid possible heat damage.

hello

what is huming?if its your amp unplug everything and just leave your speakers hooked up.if its huming ists your amp.if no hum your amp is fine.do not unhook your ground.

next hook your dac to it with nothing hooked to any inputs.next start hooking one input at a time.if no hum then start to hook your preamp up to the outputs of dac one cable at a time and listen.

after that start to hook up other sources and you will find the cause of the hum.

but by no means disconnect the ground because if there is a problem with the grounding you could hurt yourself.

i have the full stello line and i could tell you that they are dead quite.

if you have your tv hook to it the cable or sat has its own ground and will make your system hum.

they make audio and video isolation as well a cable isolation.

let me know what happens

good luck.

What do you think about the bass performances of the two?

Almost 2 weeks and no DA100 to be found anywhere in sight Maybe I should look at other DACs (Purchasing a DA100 from April Music would be too expensive at nearly $800)?
