Hello, Paulee.
Unless rustydoglim says otherwise about his DAC-9, your DAC will probably change its sound over the next couple weeks (depending on how many hours it gets). Many DACs need a good hundred (or more!) hours to burn in fully. During this burn in, you may notice changes to guitar, piano, vocals, etc. As tempting as it is to listen for changes straight out of the box, even better sound is waiting for you a hundred hours from now.

I wouldn't be surprised if you keep noticing big improvements in your music. The DAC-9 must be much more capable than the DAC inside the Yamaha AVR. [
About three years ago, I went from a Denon 2113ci to a Cambridge Audio DACMagic Plus. There was a huge improvement!] I don't even want to think about how much better the DAC-9 is than my DACMagic Plus.

It's nearly time for me to upgrade my old DAC. I'm really looking forward to it....and I'll try really hard to allow it to burn in completely before I over-analyze it (I hope!).

Listen to all your favorite songs now. Are there any "Wow!" revelations?
I'm an old (too old, perhaps) Pink Floyd fan, so I like that choice. Minor Majority is new to me, so I listened to that song on YouTube. I like it. I'm not too sure I care for 'How does it feel', but that might be my 'censor' kicking in. I suspect D'Angelo enjoyed making that video. I've heard of the Punch Brothers, but I'm unfamiliar with their music. I'll check out Julep right after I hit 'post'. [Edit: Yes! I like Julep. Reminds me a little of Sarah Jarosz.]
Post more impressions of songs as burn in occurs! And educate me with new music, please.

Regards,
Michael
