well, the Primaluna arrived and I set it up last night. It needs about 100 hours to break it in, but of course I couldn't resist and started listening to music right away. Mind you, the Plinius is a great Integrated, but man was I blown away by the imaging, sound, and control of my Summit X speakers. It was absolutely beautiful. As though my speakers came alive. This is a HUGE step up for me.
George and others, what should I listen for that will show me the limitations of tubes with my speakers? Is there specific music that will make this apparent to me? I want to make sure I grasp the effect of the impedance shortfall of tubes before I listen to the Sanders.
I also received the Sanders ESL amp today. Going this route will be more expensive because I would have to buy a preamp eventually. I plan to use the Plinius as a preamp initially if this is the route I go.
I will listed to the Primaluna for about a week, then move to the Sanders. Setup takes time to move back and forth, so I'll probably spend about a week or so with each and then make a decision.
