I’m currently running and generally liking Mundorf SGO coupling caps in my EL34 based amplifier. I’d like to preserve the spatial depth and overall energy in the high frequencies, but build out some weight/texture/tonal color in lower registers.

Would the Duelund CAST Cu/Ag be a good choice? 

I’ve used Jupiter caps, as well as the Audyn True Copper caps to great effect in other projects, so I’m familiar with the contenders. That said, I’ve read that some folks did not favor bypassing coupling caps, which is what the CAST hybrid cap is in effect. Ultimately, I’m looking for a vote of confidence before making such a non-trivial investment.
