I don't THINK this is the placebo effect

...if you hear a difference that you like…that’s all that matters.

That's all I'm trying to say happened. I haven't spent time recording before and after. I don't really care. It's about how I perceive the difference, and in all likelihood, I'll end up swapping again, but getting a small but noticeable tonal upgrade for $13 seems worth the price to me.

For what it's worth, I think there might be slightly less noise as well.

I also absolutely think it’s worth the price to swap tubes. It’s worth even more to me than $13, but whatever you spend and get a return that you appreciate…that is the point that matters. There are a bunch of people that don’t hear the difference in tubes. They can spend their $13 on a Big Mac combo or something!!

It is the placebo effect. If the tube isn’t defective or way out of spec, it does very little.

I don't agree, I mean it's not always clear the effect, but differences in construction make differences in various parameters, say microphonicity (sometimes making difference in resonance freqs and armonical contexts) , capacitance, inductance ecc. , all these things could have an audible impact
