Dlcockrum,
Humm,cnn. Who‘s owner of cnn? He dumped his chinese wife right? You think i agree anything nonsense little Cumo makes on cnn?
Regarding mod, as mr chen claimed, only good judgement should be based on golden ears,if and only if, no other way. Money is not, approach is not (tube vs solid state), feature is not even a fact for audiophilers. I perfect ok that none of my amps and lp turntables have remote control. So, why some device makes bettet sound? In dac case, in dgital domain, once power is clean, clock is acurate, data stream just feed the same dac chip w/o any difference (nowadays, chip makers reduced to very few anyway).
So the answer is how analog signal get filtered and amplified from dac chip analog output pins.cheap approach is ic based low quality circuit used in tv and computers, those design should not used in high end audio. But selling audio equipment is a buisiness, cnn like media feed all kinds of crab to confuse consumers. Use your ears, not looking at price tag to decide which one is better.
As oppo dac goes, it is my attempt to play both cd and dsd lp achieving files with a mobil phone app. I actually would be happy if it is half good as my assemblage. Now it exceeds my expectation:it has latest dac chip, it uses one of my fav voltage amp ic 4562, its usb interface is decent.i just fixed the weak spots of power supply and coupling crab(good preamp should never use capacitor coupling unless western electric ultrapath design for tube amp).
Btw, my korg dsd recording has same issues and more(bad ic chips in signal path), so i have some experience to deal with unnecessary coupling. In korg case, i just short the caps. My phono stage line out is transformer coupled, no reason why recorder needs coupling caps in front.
