It was more detailed and soooooooo much smoother. I could play at higher volumes and it wasnt harsh at all, whereas my avr was. A live album that i listened to on my avr sounded live and unpolished, the peachtree made it sound like a professional recording. I couldnt believe it. What can i attribute this to? the quality of amplification? its dac? i was airplaying vs usb cable, but dont think that makes a difference.

A long time ago, I had a tube system that added "warmth" to everything, and made Jimi Hendrix sound like Mozart (not literally, but I hope you get my meaning). This was subjectively pleasant. The thing is, Jimi Hendrix is not supposed to sound like Mozart.
I see that higher than normal distortion and frequency response anomalies are the case with the Peachtree decco65:
So, if you like degraded sound more than what was recorded, you may prefer the Peachtree approach to Yamaha's accurate reproduction of the signal.
In other words, you can attribute the difference to the poor design of the Peachtree. (Some of the poor aspects of it have nothing to do with tubes, but are the sort of thing that tube lovers often like.) You get extra distortion, and a screwed up frequency response, that subjectively smooths off the rough edges, as it were. Consider your own description:
A live album that i listened to on my avr sounded live and unpolished, the peachtree made it sound like a professional recording.
In other words, the Peachtree made it sound like something other than what it was, whereas the Yamaha gave it to you accurately.
If you like it that way, that is fine, but do not fool yourself into thinking that it is more accurate. Jimi Hendrix sounding like Mozart had its appeal, too, but I would rather have him sound like Jimi Hendrix. And when I want to hear Mozart, I put on Mozart.
