That QLS is neat. And yes the remote control is something I'm living without right now and it sucks. So a source with a remote is cool. Most of my audio comes from .flac files now so I guess converting to .wav is no problem.
I'm building a portable tube amp now to see what tubes sound like. And if I like them I plan on getting the schitt lyr amp because it is supposed to drive the k701's I have very well.
That being said, because I'm new to this, I was assuming I need to get a good source next, and my assumption was a good CD player, but if I can continue using just "digital media"... I guess I need to solicit more advice at a higher level first and learn some more.
So maybe I should ask, what makes a good source? I'm assuming components used to make said device. But then that source may need help from a DAC and/or amp to power headphones to the headphones full potential.
Thank you guys for taking the time to help me. And sorry if this is basic questions and is trying your patience

I love listening to music and I dont have a guru I can talk to other than the Internet.
