Coupling caps

I own a Tube Audio Lab WE91 300 amp and a JE labs linestage. They use Jensen aluminum foil POI coupling caps and I am thinking about changing them out.

I have some Jensen paper tube copper foil PIO caps on the way and was also thing about the Dueland copper cast and Jupiter copper foil paper/wax . Has anyone changed coupling caps in any of the TAL equipment or can venture opinions? There a lot of "shootouts" around using different equipment so there are system and listener dependencies in these evaluations.

Personally, I value a smooth midrange as opposed to extended treble as I have some hearing hyperacusis issues that make me very sensitive to upper mids and treble such as sibilance.

Jarrett, I am a confirmed cap roller and have checked myself into a 12 step program to break the habit! Based on what you are saying, and I share your sensitivities to upper mids and highs, your best choices would be....

1) Arizona Capacitor Green Cactus caps - best choice and $25 each
2) Jensen paper tube PIO and Jupiter copper foil or aluminum flat stacked

I have rolled in SET amps like yours and these caps will indeed please you greatly.

Just call them and give them the value you want. Make sure you know the uf value and voltage rating. I purchased .47 uf at 600v.

They require you to call in. That is what I did.
