Try swopping (temporarily?) the Prologue 5 for a Dialogue 5. Listen to your favourite music with the switch in both positions. Take notes. Your ears might tell you which they prefer.The only reason I ask is that I have a PrimaLuna Prologue 5, which I adore. I understand the Dialogue 5 is the same thing but switchable between these two modes.
Thanks for that Bish, really helpful, especially as we have very similar set ups. I might keep a casual eye out for the triode mode 4 power valve model (I forget the name !). Cheers.I've got a very similar setup to you Ian, Croft 25R, Falcon gold badges, and a primaluna - the dialogue premium. I find both modes are excellent and the differences are subtle but in summary:
- Triode - beautiful midrange and excellent for vocals, sweet and smooooooth, less meaty bass but probably better controlled, rounder than UL
- UL - bigger bass, bit more in yer face presentation, great for electronica. Maybe less ultimately defined/detailed but beefier sounding. more snap
When doing A/B comparisons, the volume obviously increases in UL mode so that might give the impression it's more dynamic than Triode as an immediate reaction. Triode mode definitely most effective imo with an EL34, and I spend most of my listening time with EL34s and triode mode engaged.
So much for I’ve finished after 43 years! Anyway hope that you are well and have filled both hard cases with valves!!Thanks for that Bish, really helpful, especially as we have very similar set ups. I might keep a casual eye out for the triode mode 4 power valve model (I forget the name !). Cheers.
Exactly, hence I rushed to change my original post, but I think you may have got to it before I did!Thanks Jules but are you sure? I know the 'dialogue' premium can be switched but I can't find anything on the 'prologue' premium model
