Sorry guys, I thought I was clear, but now I realized it was not clear enough, even though I tried, by stating:
"..Even a cheap dongle type will do a good/better job if you use it with an AVR's analog input, direct mode to bypass the AVR's ADC/DSP/DAC block..."
So, my whole point was based on using something like that (ie. such a cheap DAC including the dongle style ones) with an AVR, instead add an integrated that has functions and features that may overlaps with their AVRs.
We all know forum members often asked if they should us an integrated amp with their AVR, with/without the so called HT bypass, and if I were to say yes, I would suggest they get one without build in dac, but buy a separate dac. That's really a point, I should included more details.
And, I would always recommend integrated amps (in the <1-2K price range) that is more of the old traditional style that does not include digital inputs, for the very reason I tabled.
Note: I also know that many members will not consider using an AVR for 2 ch stereo use, so that's that..
I edited the thread title, hopefully it is clear now, if not, please let me know so I can edit it further as I don't want to mislead anyone whether they agree with my suggestions or not.
