I finally got a new multimeter biggrin.gif ... and a chance to measure DC offset on the Line out and HP out again.

It looks like HP out is worse.

I got 130mV and 145mV DC (pics 1-2) on the two channels respectively (0.13/5v biggrin.gif pic 3 ). As far as I'm concerned that's pretty appalling considering the AC voltage for the IEMs volume was about 600mV (Look at the tangent opamp page, he says even DIY crappy amps shouldn't have > 100mv).

This is very very very disappointing.

Measured line out again, (pic 4), and it's 70mv frown.gif (oh and yes, it's badly out of focus, but I can't be bothered retaking it, since there are a few pics of the same measurement for line out with my old fluke mm, before it died)

bleh.

250 (hp R)
250 (hp L)
250 (hp L, V instead of mV)
250 (line out)


The last pic is a baseline measurement of the DC offset on an external amp (showing about 4mV)
250

my beloved Firestone Spitfire DAC outputs 3mV on the L and 4mV on the R...the HA-160D 0mV on the HP out.

 

your sales pitch isn't very effective anyway biggrin.gif

lol... I just realized that there is no digital out (coax, toslink, etc are all ins biggrin.gif )... That means I can't even use it as a transport (combined with the analog section being all fubar it's not really useful for anything it seems)...
Oh wait, it is...Now it's serving as a glorified monitor stand biggrin.gif

mmm yea... So basically the DC offsets are by design and the power button issue doesn't look to be a power button issue but the bootloader or something. In other words, if you buy one of these, be prepared to get a HP and line out cable with some capacitors in line biggrin.gif

Output impedance on the headphone out is too high (I somewhat suspect it's higher than the quoted 2ohms). Low impedance/high sensitivity IEMs (e.g Unique Melody Aero or Mage), sound terrible and have interaction issues (high noise floor, distorted frequency response). Even hp out 2 doesn't seem to fix it fully.

Not something I'd expect from a $300+ amp/dac. Will be buying an nwaguy o2 amp for low impedance headphones and iems.

new beta drivers and firmware are out (a year + after last firmware and drivers)
http://dl.musiland.cn/beta (uninstall old drivers, reboot, install new ones, flash firmware.... There's also something that updates the 'boot block' but I don't see it mentioned anywhere...yea)
Finally upgrading MDxx series owners to the new control panel style and adding a 5 band hardware-ish-EQ (mudsp) and 32b/384k bit/sampling rate (yay new bugs biggrin.gif )

svyr,

 

These drivers are for the MD11 exclusively?  I have an MD10 and 01USD.  Never messed with the MD10 driver wise but have updated 01USD a couple times.

MD11 and MD30. 10 had a different architecture. Not sure about 01 - monitor series has its own FW and drivers (you can try upgrade it to the latest firmware marked as *mon* in the dl and utils folder above)

So....have the drivers fixed all the problems on this unit?

 

A buddy of mine wants to trade DACs(a musiland MD11) with my Xonar.

 

Is this unit really that messed up!?!

 

How's the audio quality compare to a schitt modi, yulong, or HRT DAC?

 

Maybe the $300 purchase price went to the sweet blue screen!

 

BTW.....is this unit horrible for the price of $300 or just a craptacular DAC even after firmware updates?

 

For example, I planned on buying a Schitt magni(I'm using more so for the DAC than head amp although that's useful too).

The drivers haven't really fixed anything since the issues are in the hardware (output circuit design for the line out and headphone out sections - namely DC offset for both, and high output impedance for the HP out)
Just about the only nice thing about it is a bulk mode USB implementation that you usually see in pro-audio cards, or high end DACs.

if dc on line out, or HP out don't matter to you - it's fine (err, not too sure what else you'd use it for). The new v2 drivers are still buggy as they introduce new features, but not too bad.
MD11 is pretty much unsuitable for IEMs or low impedance+high sensitivity headphones (buzzing/noise and frequency response curve interactions) or amps connected via line out with high gain and no DC filtering. (e.g. stax amps)
If those don't bother you - by all means trade for it
They're possibly suitable to drive 300 ohm HD650 or 600 from the built in amp (with 600, it'd probably give a pleasing laid back sound, and the HP out problems probably won't affect HD600 much).

To be honest, I'm not sure what the alternatives at say $100 are (today), but I'm sure you can do better.
