SCD-1 & SCD-777ES Sonically What's the Difference?

The power supply is the same,it's the 2 encapsulated transformers($340 without labor)that is the main difference.Add to that,the fifth foot,balanced outputs(fake or not,it can still be used with balanced equipment)and don't forget their difference in appearance.I did prefer the SCD-1 to the 777ES when comparing the two,though it was not night and day.I do feel the transformers play a large role in regards to these differences.Gary.

I have a pro audio background, and every time I see someone calling a balanced out a "fake balanced out" I have to laugh. This is one of those tweaky audiophile distinctions that is lost on the rest of the world.

A balanced output simply means that there are two signals - the original and an inverted version. They share a common ground. The whole point of a balanced out is to allow for very long cable runs without introducing cable-induced noise, or losing big chunks of signal. So, a balanced output enables common mode rejection, and has high gain to support the long cable run.

The balanced outputs on the SCD-1 do this job just as they should. So how is that "fake?"

And yes, I know about an inverted signal derived from a "differential" split output versus an op-amped flip-flop. The fact is that it makes no difference regarding the purpose of a balanced out. Most pro audio gear simply flips the signal with an op-amp or similar inverter circuit.

Some units have two DACs outputting a true differential signal that is then amplified in a differential analogue stage.

An op-amp inverter used to create a balanced signal does, as you say, provide the balanced output that is useful on longer interconnection runs, but the typical user does not run such long interconnects. These users expect a better quality signal from the balanced output (I don't know why), so an added stage that may degrade the signal is a bit of a disappointment.
