I have mine for two weeks now and just LOVE the sound it give my Sennheiser HD598

I only use USB power, I try but don't hear any difference in the sound quality on my HD598.

I use it together with a S.M.S.L SA-S3 T-Amp, and ProAc_Response 1SC Speakers

Talk about Micro Stereo with a BIG sound :-)

But you need a clean USB with full 5v power, (Not a USB HUB) to drive it

 

Fantastic sound from all of it

does the optical input and output work as a pass through to another DAC? if yes, does the unit need to be powered on for the passthrough to work? thanks!

Yes you need to have power on if you use Toslink

Trying to decide if I should replace my Modi+Magni with this one. Magni has way too much THD when the volume knob is turned past 2 'o clock (needed for my 600-Ohm DT-770/880), Modi has inverted signal and is very sensitive to USB noise.

Anyone who heard the HUD-mx2 and ODAC+O2 and possibly the Schiits to give any comparisons? I am deciding if I should replace the Schiit stack with the HUD-mx2 or ODAC+O2 combo.

 

So.... can anyone provide a comparison of the HUD-mx2 and ODAC+O2?

post #290 of 298

Compared to the O2 combo:

 

More input/output options.

Cheaper.

 

 

I listen to Sennheiser Momentum over ear and Klipsh S4i in ear on my MX2 which are sensitive cheap noisy amps.

 

The background is quite inky blackness as loud as I can listen to it, which is only about 1/2 I've never had to go higher.

 

I hope that helps a bit.

I ran off of USB power for months with no problem other than the lack of volume for my cans. Power from socket made a world of difference, perhaps on sound quality as well. I use the optical ports of my computer and the DAC and I get power from the wall socket. It's quite reliable.  I use a pair of Mad Dogs, for what it's worth.  

Hi, I'm new to head fi and I'm in the market for a pair of Mad Dogs and an amp/dac to go with it. How do they sound on the MX2 (does it make it harsh/bright)? Do they need a more powerful amp or with it plugged into the wall enough?

Any help would be much appreciated.

Cheers!

I have decided: will buy both. O2+ODAC is already here at home and gosh it's great, HUD-mx2 on its way... I like to waste money on nice devices which are different but quite the same :)

Just sold my Modi and Magni stack. Modi was quite worse than my E-MU 0404 USB and Magni had quite high THD with volume past 2 o'clock (needed for 600-Ohm Beyers).

Also selling my Graham Slee Novo right now. Bought in 2009, every year I had it I was realizing more and more what a waste of money it was...

I also realized recently that I could not tell the Magni and Novo (except that the Novo had audibly rolled-off bass with low-impedance phones) from the headphone output of my E-MU 0404 USB. I wonder if in some time spent listening to it I will be able to tell the O2+ODAC and HUD-mx2 (once it arrives) from the EMU 0404 USB headphone out. Right now I feel like the O2, when driven from the EMU 0404 USB, has more dynamic and clearer sound than the EMU 0404 USB headphone out, but I'm not sure I could tell them apart in a blind test.

I wonder how the HUD-mx2 will compare. Considering it has no analog input just for the amp and it is always being driven from the integrated DAC, I wonder how will I be able to evaluate the sound of its amp. Maybe just by using its analog line out feeding the O2 and then switching to the Audinst's headphone out...

Anyway, if I do not forget, I will share my experiences.

I recently experienced that the line-out sounds worse than the amp-out. Never needed it before but got a dedicated headphone amp and therefore used the line-out for the first time. Thats why I had to get a new DAC. But I´ll keep the Audinst for travelling.

Having that said I would rather suggest to use a 3.5mm headphone jack to rca cable to feed the O2. The Audinst can drive both headphone outputs at the same time.

Hi everybody,

 

I have slight problem with my MX2. A couple of days ago it stopped working. When I plug it into my MacBook Pro via usb, it is recognised as an external usb audio-device, but not as hud mx2 anymore as it did before. The indicator is on red no matter in which of the two usb-slots I plug it in. First I thought it might be the cable, so I changed the cable: but still, the indicator stays on red and no sound (I plugged the ac in in a second step to rule power-limitations via usb out: still red light). I plugged it into a windows-machine at work to figure out if it was a problem with my Mac, but the indicator stays on red. Anybody an idea what the problem might be (and probably even a solution)? Thanks for your help in advance already!

post #295 of 298

Just to be sure: the input switch is in "USB"-Position and not "Off" or "Optical"? 

post #296 of 298

Correct, it's in USB position. I turned it a couple of times into off-position and usb-position again, but it didn't change to orange.

post #297 of 298

That doesn't sound good.  Especially if the condition exists on two seperate computers.

 

Are you using external power, or USB bus power?

Thanks for the link (I will post my problem there when I got my confirmation email).

Regarding your question: I have used the mx2 practically exclusively via USB. But when the problem occurred, I plugged the external power in, just to rule out a lack of power-supply...unfortunately it didn't solve the problem.
