Jitter isn't much of an issue, unlikely you'll ever hear any and if you start running into posts by a guy named amirm don't say I didn't warn you. DACs are not a big worry, while of course some specs can be better than others, they're usually quite competent, it's a mature science at this point. They're far more similar in terms of audible results; did you worry about the DAC in your other avr?
Did you ever calibrate the volume scale on the Pioneer you had by running MCACC to setup distance/levels etc at your listening position or use an spl meter? Do you remember what volume setting would you play movies or music back at? I don't have an idea of what you consider loud or usual. FWIW the movie THX standard reference volume is 85dB from the speakers, allowing for 20dB peaks (LFE channel is 10dB more); music doesn't really have a standard so the number only means so much but would give us an idea of what your normal listening levels are.
Alright so I bought my Pioneer AVR with no research, just the guy at Harvey Norman recommended it to me, and I had just started working and was super keen to treat myself so I bought it from his recommendation. I still don't know what DAC it had in it - nor would I know what to look out or listen for.
I never used the MCACC setup. All I ever did was plug everything in, turn it on, make sure stereo was selected, adjust the settings with the dial on the back of the sub and watch movies / play games. I never did any tinkering with any of the settings - simply plug and play.
Now that I am taking this stuff a bit more seriously - I would really like to purchase an amp and use it properly (as much as I can with my 2.1 setup).
As for volumes - I would have no idea how loud it actually was - but I would say it was most likely standard listening. As in I would never listen to it loud enough to annoy any of my neighbours. I just appreciated the higher quality sound from it rather than the crappy tv speakers.
Sounds like if I selected any of these Yamaha's and set them up with their YPAO function I would benefit to what I had previously lol.
