In your original post you expressed an interest in a 300b SET amplifier. In my opinion your current Viking speakers afford a terrific opportunity to explore the possibility. 98 db sensitivity horn, I’d encourage you to go for it.
You have had previous push pull tube amplifiers that you apparently enjoyed quite a bit. A good quality 300b SET will provide a different listening perspective/encounter. Whether it’s better or not is for you to determine. Is your speaker the 6 or the 12 ohm impedance version?
