Only one source well it depends on where I am, I can't take my TT with me on long vacations to some place in the US other than my home. I can't take my TT when I drive around in my car on a long trip. I don't own thousands of LP's ( hundreds) I really haven't seen anyone getting by TSA while carrying their TT to listen to music, while at the beach with the wife, I use my smart phone and some good ear buds, so for a total general use "everywhere" one source, I'm picking door number three = digital.
My Astell Kerns Ak240 along with my smart phone does just fine when I'm away from home. Now if I'm stuck at home with No where to go, and since I enjoy music, it's my Lumin 90% of the time since it allows me the choice of a vast music selection from downloads, my rips from SACD's and CD's, and its excellent access to Tidal. Now if I like something I hear on Tidal and if its available on LP, I buy the LP, because I do enjoy vinyl.. But a lot of the music I grew up with is NO longer around on vinyl which makes my music source selection easy. Its all about the music. Without the music you actually enjoy, a source just becomes another box on a rack.
