I'm sure you've already asked yourself this question but do you recall if your old ones sounded great right out of the box or if they too blossomed with decent burn in time?
300b tubes burn in time?
I just bought a new pair of Shuguang Black Treasure tubes. For some reason they don't sound as good (open, detailed, life-like) as my old ones of the same brand.
Do you know how many hours 300b tubes take to fully burn in?
Or I am wondering if I got some sub-par pair of tubes.
