While I have been playing with audio gear for over 40 years, a lot of audio gear, been selling high end audio, I have very little knowledge re. circuit design etc. The DIY bug bit me recently so I have been trying to absorb a lot of information regarding circuit designs, tubes and speakers.

I'm about to order a TU-8900, which as I understand has plenty of gain, and reading about "Gain Structure" adding a pre will likely raise my noise floor and of course impose its sonic signature. My system currently has 2 sources, LP, building an Eros 2, and currently a Bluesound Node, waiting for an ANK DAC 1.1, and a powered sub. Is there a better way to have source select, ideally for 3 inputs, a pre out for my sub and remote volume control?
