Indeed, DACs always have analog circuitry that can be subject to noise, introduce distortion, etc.Oppo made great stuff period. In fact they made the best Blu-ray players period, and I'll show data to prove this. And despite what some people who don't understand how digital actually works think. There are differences in quality with digital. It's not nearly the same at all. Those 1's and 0's have to be decoded. They have to be read from the disc if it's a player. There is an analog output section in it like anything else that requires capacitors. There's power supplies that can introduce noise etc. I have incredibly sensitive ears, and I can't even listen some DAC's without getting a headache. ...
In the purely digital domain before the DAC, a transport either works or it doesn't. It either delivers a bit-perfect stream of data from the disc to the DAC in a timely fashion, or it doesn't. There is no such thing as "quality" to a digital stream. In modern buffered (and re-clocked by the DAC to avoid jitter) digital systems, it is correct; or it is incorrect; or it is correct but delayed enough to allow the buffer to empty.
The latter two are forms of failure.
In short, all working purely digital systems are the same: They emit the data from the source media without even a single bit of change. Deviation from this -- emitting data that does not match the source, or delaying it enough to cause problems -- means a purely digital system is broken and not working.
Note that players with DACs are not purely digital systems. They are digital plus analog systems -- a digital transport plus a DAC, and a DAC always has an analog subsystem -- and not all analog systems are the same.
Indeed, analog systems can be very different. Working digital systems cannot be different, or they're broken.
