Well I fired up my Torii a while ago and low and behold my Valve Art 274 tube in the right channel was glowing a very cool purple. Also at the same time the OA3 was shooting lightning inside of itself. Is this normal?

So right now I'm listening to my Wadia 151 PowerDAC mini. It is so so.
It looks like I need to get off of my wallet and tube up.
I know I have asked this before, but I'm too lazy to look back, But what is the hot setup for a Mark 3?
I'm thinking about changing everything out and starting anew. Might as well do it right.
