You found the same scenario a lot of is found..The K40Y-9 and the Vit Q are two of the finest sounding coupling caps ever made..Obviously they were both built to high standards because both were used in military applications.
The FT2s which are the 200v rated teflon caps that are capable of much higher voltages to over 750vdc in several tests..You have to mix coupling capacitor types to get a good balance..I typically use paper in oil or teflon on the output and driver stages and I use film and foil on the low voltage sections.
The thing I don't like about the Mundorf silver foil is the fact that after month,they can take on a harshness. I use them but in very selective areas.
I would try a mix of caps in your 8B..Did you try the 6L6gcs or KT66s yet in your 8B? It may be the alternate sound you are looking for.
