At the beginning of this review, we called the M33 an innovative new design. Looking at the distortion and noise results above we can confirm this. We believe this is the best performance to date of a stereo or AV product, that has no analog volume stage. It’s the AKM AK5578 chip used with four converters processing one channel. Wired this way this ADCs performance is about as good as can be achieved from a single chip. We know of no other consumer product with this ADC performance. We believe we are the first to extensively examine the preamp-out performance of the M33 and note the performance standard it has set. Only a relay-based analog volume or a volume using an exotic current mode multiplying DAC with laser trimmed film resistors will provide a significant improvement over what we see here.
