To make it a bit more clear, I am not talking of Chips/etc. in the units other operating parts, but in the audio signal path...what you hear, not what makes the display work.
What are the DACs that use good circuits in the Audio sections?
I will admit that I have never meet an integrated circuit that I thought was worth my time/money. That said, is there a good DAC that is good in the conversion process but also has some real components in the audio section rather than "chips".
