My dac automatically acknowledges when an HDCD disc has been inserted into my transport, and I must say, I enjoy greatly how they sound.
For OPPO owners. HDCD function
For many years I put the HDCD setting to ON in the settings function, with the confidence that Reference Recordings which use that coding would sound as they should.
I always wondered why those encoded CDs never sounded very good. Indeed they sounded flat and lifeless and at a very low volume.
Lo and behold, I turned OFF the setting today and the same recordings came to life with much higher volume and greater detail.
Is it my machine or a design flaw from OPPO?
