Hi Freediver
You're seeing more people heading toward one source systems these days. One reason is because having one input is better sounding than multi inputs. The other reason is systems are designed to favor one input over the others. Meaning if you tweak your system to work it's best with your vinyl it will not sound as good with your tapes, cds or streaming. Every source requires it's own system setting to get the most out of it, just like every recording is different.
