For me it's always been about experimentation and finding synergistic pairings in my gear. I never really set out to go tube or SS in particular. I just try everything that looks interesting and see what works for my tastes. Sometimes that is tube based, sometimes solid state, sometimes hybrid.
Right now I've got a Lampizator tube DAC and a Unison Research hybrid integrated. I love the sound they make together. I don't think it's necessarily just because of the presence of tubes or not, just the designs of these particular devices that hit the spot for me.
