I'd be interested in hearing both your immediate opinions and then your opinions after the 'burn in time'.
Murph. This is my first piece of tube gear so I'm definitely no expert.
I don't buy into the whole "burn in" thing when it comes to SS gear or cables, but from what I read(and you can take it with a grain of salt)tubes do benefit from burn time(extended usage to a point) and it makes sense. Or maybe I took your post the wrong way?
Any way... I'll use the 6j1 and the JAN-GE 5654W and report back if interested.
