It is 20% VAT + a customs fee.

Surprisingly, they don’t make a massive difference, but I feel that the music sounds more detailed now.
Placebo effect? Maybe….

Will I be doing an A/B? Nope….

I had a late nice listening session last night using headphones, and I swear that I was hearing detail and separation of instruments I have not heard before. At almost €30 each (after shipping and import tax) they are expensive, but they are easy to fit, and seem to be a much better damper than the o-rings I was using before.

My tube dampers search is over. I am glad I only needed three!

Ah yes I remember now, quite a different approach to the old rubber condom!

Exactly.
User feedback played a great part in my decision to purchase.

We also have Herbie’s opinion here - https://herbiesaudiolab.com/pages/he...per-comparison which was interesting to read.

And in my search for the best “new” 12AX7, they were also mentioned at the bottom of this piece - http://www.audiodrom.net/en/special-...lmost-no-money
