Hey ASR are you in Korea now? I might acquiring it too but drawback is the HP100 doesnt have balanced input.

seems to me that there should also be an HP100 signature that has balanced inputs as well as balanced headphone outputs. or what's the benefit of the balanced outputs on the da100 signature other than using other headphone amps?

Nope but I'll be traveling there soon enough.

i think they introduced some speakers as well, so the DA100 Sig might have been aimed more at this set-up via their power amp.

Look for the I2S jack on the back. That'll tell you.

Looks like they've changed the power and upsampling buttons too. I kinda like the feel of the old toggle switches... I wonder what the action on the new push buttons is like.

The old DA100 is now in the house. pics to follow.

now D1 will have a long vacation.

Wow, just read about the balanced outputs. I think I am going to come back to Stello now =] The only DAC in the $1000 range without extra pile on it (hp amps and blah blah blah).

Hi Malos, could you please post the link regarding balanced outs. Thanks!

I just got my HP100 and my initial impressions are very favorable. Very neutral sound, crystal clear, tight bass, plenty of power. Works great with my X-DAC V8. Also, really great construction. Fat face plate (helps the sound, right?), Mundorf decoupling caps, Alps pot, Neutrik XLR headhone jack...

Very happy so far.

I have a technical question.

The output voltage of DA100 DAC is 2.4 Vrms.

HP100 AMP has a High/Low gain switch to change the input sensitivity. When it’s set to “High”, the input sensitivity is 1.5 Vrms. When it’s set to “Low”, it is 2.7 Vrms.

I thought that in order to avoid the sound clipping, the output voltage must not be more than the input sensitivity.

So, from the technical point of view, when using the “High” gain setting, is there any problem that the output voltage of DA100 (2.4 Vrms) exceeds the input sensitivity of HP100 (1.5 Vrms) by so much?

Any thoughts would be very much appreciated!

I believe you should set it to "LOW".

I'm searching for a DA100 (buying it directly from Korea makes it so damn expensive...
