Musiland MD30 is out (musilol)

I am and I would like to assure Musiland that so is everyone else!


Will we be able to enjoy the successor of the epic MD11 with:
a) buggy drivers and firmware without change logs or proper testing/QM or release management or installation instructions or manuals to reflect the changes in operation,
b) high noise floor due to PSU issues,
c) intermittently working power button and the
d) fiddly navigation with 1 overloaded jog dial doing everything. The jog dial that has to be authoritatively gripped holding your hand directly opposite it to turn (otherwise it slips) (and is overloaded with to nearly 0 usability with all actions being via it)
e) instability at high ambient temperatures (freezes).
f) overstated specs? quoting not measured specs, but DAC chip specs - see b), extrapolate the effects to SNR . (also, half of Soomal's RMAA pics are for some reason gone now and only the 44.1k measurements are left up)
g) nearly 100mv DC offset out on line. Goes really well with your directly coupled amps (it really doesn't)!
h) a nice looking box with 0 corner strength and undecipherable marketing gibberish on it.
i) sound quality severely degrades for higher impedance headphones (e.g. GMP450 PRO), sound sig becomes mids centric and hollow. Distortion/noise floor also raise significantly to make things even worse
j) Polished metal conductive and GROUNDED front plate. Touch the USB cable while touching the plate to be pleasantly surprised.
k) HP out has 150mv of DC on it... fail.
....

?

All this, for only $600 RRP + local dealer markup and shipping! (plus the approximate $100 on you sending a couple of units back to hopefully get a working one, because of epic QA, although I guess you could have a good seller who's honest and all...)


What's there not to be excited about?

DAC chip: ADI (Analog Devices Inc.) AD1955 company

FPGA芯片：Xilinx XC3S250E

With AES / EBU professionalDigitalInput. With Canon (XLR) balanced analogOutput. There is no limit between the two does not mean that only AES / EBU signal to come through to the output XLR balanced. All digital inputs, including MULINK, coaxial RCA, coaxial BNC,Fiber, AES, or evenUSB, Can be balanced by Canon to output.

And MD11 asMD30The USB is not a traditional PCM2704 and the like, butMonitor 01 USD, as designed, and MD11 than the Monitor 01 USD and the USB to be good. It is done in the FPGA chip, it is necessary specialized equipmentDriver. Signal precision than a lot of PCISound CardDigital outputs are good. It is worthwhile to compare the PCI Love your sound card and MD30's USB, then you hearFeelingDecide which to use.

And a lot of different codecs, MD30 is independent of the clock decoder. Explain.
Let us talk about principles: sound card via coaxial, optical digital connections in both the signal sent over the data signal, another clock signal. Good understanding of the data signal isSoundTheir own content. What is the clock signal? Music is definitely with theTimeClosely related to it, what time is set out what sounds good. So just as we sing, beat time, like playing musical instruments, sound cards, play a sound decoder, the data also need to have "beat."PCRecord audio data is in one of a number of forms, the number of positive and negative, said vibration direction, the size of thatVolumeSize, according to the scheduled time shown these numbers to become a continuous heard music. For example, our most popular music files,SamplingFrequency is 44100Hz, the number is 44100 per second, number and interval between the number of 1 / 44100 sec.
So what, sound card, the decoder according to this beat a number one player, we can listen to music.
In fact, the "beat" is not absolutely accurate, the sound of the clock source will be errors, coaxial, fiber optic transmission will cause errors when there is always error, will be faster, slower, or rhythm instability , when the fast slowly. So in the sound distortion.
General decoder, which failed an independent clock, it's "beat" is the sound card provided to the clock signal and data signals together a good compilation code (easy transfer), in the coaxial, fiber optic lines in the pass over, the digital receiver translated back to the I2S format chip signal sent to DAC chip digital-analog conversion.
The MD30, what he himself has a clock, use the DDS generated (Direct digital frequency synthesizer, see Baidu Wikipedia, here:http://baike.baidu.com/view/38405.htm），High precision, up to the MD30 in 1ps. For received data, MD30 as long as the data signal part, for the clock signal is ignored, but with their own high-precision clock to play it. In this way, "beat" playing a more accurate, the soundSoundAlso been a considerable increase.

FIFO pointers, the start, the pointer will swing around the clock with the input signal, and finally stopped at a certain place, which indicates that, 1ps programmable clock and clock synchronization on the input.

To the other Chinese audio manufacturers - love your work, guys.

Relatively high-frequency detail more MD11 stretch, the sound is more loose, but the transient performance and very good. Overall, MD30 MD11 relatively clear voice quality improvement, the sound has some different styles.
