I can read on other sites but I trust YOUR ears more... re. tubes

I picked up a rather inexpensive 12au7 headphone amplifier. I read the stock tube is a basic Chinese POS, I am wanting to upgrade to something that is warm with nice controlled bass. Any ideas on possible replacement 12au7s?

I read the Mullard's are a nice warm sounding tube but you will have more experience than I. Before I pull the trigger inform me, I am COMPLETELY new to the tube world and should be treated as if I know nothing.

Thanks in advance!

    There are lots of good 12AU7/ECC82/5814 tubes out there.

    If you do a search using heiney9 there is a ton of info I already posted.

    I may have some for you as my collection is quite large and I am always paring down. You need a single or a pair?

    Single 12au7 tube for this amp.

    I have read quite a bit on your tube posts. Sometimes I can follow along other times it is like reading when people are building crossovers ha! Too many euphemisms for me to catch up sometimes. I will take some time today to run over a couple articles of yours today @heiney9
