@roxy54 I would have to imagine Atma-spherica is how a good Atma-sphere system makes your room sound. ;) And to the OP a good preamp should make a significant difference and your ideas are good ones.
I’ve got the upgrade itch
Thinking about going back to separates. My current setup is a Primaluna Dialogue Premium Integrated amp. Since the Primaluna has an HT input, I can do the upgrade in two steps, upgrading the preamp first. I am thinking about a 6SN7 based preamp, such as Sachs, Supratek, or, an Atma-Sphere MP-3 (if I can stretch the budget).
Question, will the preamp switch make a big difference over the preamp stage in the Primaluna??
