Great questions. Could I suggest you post this as a new thread and delete this. It is a great question. But this is already a long thread.
I’d be happy to respond. Big questions.
Primaluna?
I’m thinking about giving a full tube setup a go and Primaluna in particular. Looking to hear people’s experiences with Primaluna in general. My main draw to them outside of tubes is there auto bias and protective features. Wondering if people generally replace a single bad tube or if people are replacing all tubes of that type when there’s a failure. Also would be interested if there were any other companies with at least a similar protective feature. The auto bias sounds great but the protective features are a bigger deal to me.
