Higher end Tubes for Ah Njoe Tjoeb 4000

I have an Ah! 4000 and want to do some tube rolling. Who knows higher quality tubes that they've tried with this cd player? What were your perceptions? Thanks!

I'm not sure about this, but is it possible to try alternative tubes like the 7DJ8 or 6ES8? If so, has anyone tried them, and to what affect? Appreciate the info!

Not interchangeable. You just need to pay up for the NOS tubes
