@bluethinker Sound signature is something I'm still trying to understand what I want. Perhaps if I share my audio journey it will help you understand what I like.
My old system was as follows....
Schiit Saga plus preamp
Schiit Modus dac which I'm still using
Emotiva PA-1 stealth monoblock amps
Magnepan .7 speakers
Some cheap cd player can't remember the name.
I remember when I upgraded the the cd player to the Rotel RCD-1572, I could hear a massive improvement in sound instantly. If was like more of the layers of the onion were peeled back exposing sounds in the recording I had never heard before.
Then I added the Modwright and Maggies and I think I'm in a better position to actually hear differences dacs, cables, etc can make in the sound.
I like hearing details in a recording that you can't hear on cheaper gear. I like a wide, deep soundstage where I can close my eyes and pinpoint each instrument and it be true to if you were watching it live.
I can answer or explain more if you have other questions that would help you recommend a dac.
