Yes, but not so much fun!Still higher quality than a $100,000 turntable.
A bunch of these may have been auctioned off for pennies when the company went bust or whatever. Plus Chinese export subsidies. Normally pricing would have been closer to the IIRC $29 for a FiiO D3... maybe 20-25.Incredible... Digikey sells the pcm1802 adc chip for 4$ singles, 3$ moderate quantity... How can it possibly add up to a profitable finished product, I'm puzzled.
I am sure a better opamp would go a long way towards improving distortion performance. Cheap,suitable for 5 V and high performance don't really go together.Would be fun to mod it to high tier performance
Why would TI auction them for pennies when they took over Burr Brown, and then keep the ic in their current catalog and not discontinue it? Cloning a chip is certainly possible but is it actually cost effective? doubt it, the main chip manufacturers are so huge that with their manufacturing facility, a smaller player couldn’t make them for cheaper. Whatever the reason, of course there is something grey here, there is no magic, but still, it makes you wonder, how the people working on this are getting paid. Volume, yes, of course. But, digikey probably over the years bought tens of tousands of these 1804. if I want one. what they paid for them, plus their margin, makes 4$ (+15$ shipping in canada) the manufacturer of his unnamed adc, also probably bought tens of thousands, and +margins+fixed cost+pcb+all other parts+connectors and case+electronic and mechanical assembly can get this to me for 5 bucks or so including shipping... and that’s if i buy exactly one unit, not a thousand, i gottavisit china more often i guess... just don’t get it.A bunch of these may have been auctioned off for pennies when the company went bust or whatever.

The suspected CS4344 is below $2 in quantity. The "unmarked helicopter" chip in the ADC may be a *cough* unofficial clone *cough* of the CS8416.
PCM1804 is a pretty good ADC, actually.

Nobody is possibly making any money selling these for a couple of dollars, not unless they got hold of them for essentially free.
Indeed. And the mystery remains. Even mostly full of jelly bean parts, there is an intrinsic floor these things can be made for that makes the prices difficult to understand.The D/A (same as @amirm reviewed) has been sold for at least 5 years on eBay in vast quantities at the same general price.
This guy uses PCM1802 which is not as good, but it was used in the first E-MU 0404 PCI back in the mid-2000s. PCM1804 was reserved for their best devices at the time like 1820M and 1616M.PCM1804 is a pretty good ADC, actually.
The "m" suffixed ones use AK5394 ADC. @AnalogSteph , it has 0.001dB ripple!This guy uses PCM1802 which is not as good, but it was used in the first E-MU 0404 PCI back in the mid-2000s. PCM1804 was reserved for their best devices at the time like 1820M and 1616M.

Thanks for the pics, would like to see it measured.This is the A/D version in the same casework. I can't seem to find the D/A- think I gave it my father for optical TV to HiFi sound a while back.

Why? You want it to be able to compete with PS Audio?![]()
