What about all those Chinese DACs?


It seems like everywhere I look, there are DACs from China that have these amazing specs on paper. SNR: >133 dB; THD: 0.000004%;

Dynamic Range: 124dB. If you really think about it, these were specs that almost didn't exist outside of pro-audio gear. A lot of these units have chips from ESS, Cirrus Logic, Texas Instruments and very sophisticated conversion circuitry.

So, my question is, what do you all think?

@larsman What's comical is the United States was responsible for the Japanese jump in quality control. After WW2 (In the early 50's) we sent a man named William Edwards Deming to Japan to teach them about Quality control. Little did we know how that would end up.

Yep, I remember Japanese goods were synonymous with crap. Then as the thoughts of Deming took over in a culture of cooperation... the quality went from terrible to outstanding. I studied Deming in grad school and had to laugh at the idea of large scale implementing his ideas in... the US where labor and management were often antagonistic.

The Sony Walkman was a revelation. Could not afford it, but borrowed an AM/FM one for some time and thought it was the bees knees. My first real purchase when I had any money to speak of was a Sony Trinitron TV, I think, 19". Not long after that, I purchased a Honda Prelude. Japan was engineering some great products at the time.

I didn’t mean the car industry went under, but their economy did via the real estate stock bubble burst.

You are a bit of an expert on China, correct? If their real estate bubble (all reports I have read is that it is far bigger than Japan’s of that time) does burst, will they enter "lost decades" ala Japan? A communist country may have levers to pull in order to minimize damage, but an economy does not care how the government is organized. Bad decisions lead to failed markets.

Anyway, human failure is at least consistent. America had the auto and tech peak from the 50’s to the 70’s, then Japan ruled, now it looks a lot like China has the same upper hand.

Of course, the oil crisis is what brought America down to earth as if we need anymore parallels of oil dominating the world order. I have read where over 50% of a car is made up of oil products. Most, I would guess, being made of plastic.

@willywonka

Good point on Deming. I guess he thought sharing would be reciprocated, or that one country could work in good faith with another.

That quality control you talk about is what is in doubt with China audio products, there is no American at the end of the production line (certainly would be for Apple products, right?) confirming measurements are fittingly correct to meet a standardization. No representation means one should not expect validation when it comes to measurements.

I am not an ASR fan, but do read Stereophile and appreciate the time and effort they take to cover all aspects of a component.

Yes the real estate bubble is real. I’d walk by these huge tower buildings... just beautiful for a couple blocks with new ones being built all around them and realize I was walking by vacant buildings with squatters camped in window wells and in corners outside the building. These would be thirty - forty story buildings. This has been going on for a very long time. 

But the Chinese government has more levers to pull than countries like Japan. They also have vast resources  and a huge labor pool that would love to have a job that paid $1/ hour. The economic boom started in the East and has been moving to the west. First the boom is started by incredibly low wage s of unskilled labor. Once they start becoming skilled then the wages rise and the management is kindled... wages rise further and they produce high quality goods and a middle class. The use of low wages to start things off continues to move West. 

Just a little note. The thing that always blew me away traveling in China was the scale. Let's say I was driving for two hours west to east. Either close up or at a mid distance I could always see six or more huge cranes on both sides of the highway building at least eight high rise apartment complex. Sometimes five or six groups at one time... continuously for hours. The scale boggles the mind. 

If you are interested I have a few of my photos posted here:

My Audio Alchemy DDP 1 (Dac/Pre)+ PS 5 power supply finally stoppeg working. I was  thinking to get it foxed, but they responded, which left me (on SS retirement budget) to explore less costly options. Being Prime member gave me the opportunity to return. First I ordered a SMSL PL200T transport $600 and a Topping D90iii Discrete 1 bit dac/ pre, which is excellent but the pre was lacking so I replaced it with Topping D90 preamp, Cables and power cords matter A LOT, but blows away the 13 year old AA tech
