@jetson I just finished speaking to folks at Ayre as you can see in my thread about the Codex. They were quite unambiguous in stating that the Codex output could very much be fed directly into a power amplifier.
That said, according to them, the codex was designed first as a DAC and a headphone amplifier. So the fact that it has a digital volume control and variable out does not mean it will perform the same as a high quality pre-amplifier. Adding a good preamplifier will definitely improve things, however, that does not mean that the Codex cannot be used to directly feed an amplifier.
He said that they themselves had done so many times.
