I perhaps should have mentioned I have a Pass XP22 pre w/ upgraded umbilical, which I do like very much given its neutrality and touch of warmth.
One part of it is an interest in possibly trying brand synergy with Pass amps, however I do really like how it sounds with JC5 albeit I wouldn't mind a touch more warmth and mid-range at times without losing detail and highs/shimmer.
I very much value all the feedback, especially from actual users. So thank you for sharing.
