I ordered full music gold pin with gold silkscreens from my local hifiman dealer - what a difference, like night and day comparing to not 'gold pin', it is completely different inside when you look inside the glass ... so I was right about it, it is low budget version which is now added as a stock tube to ef-5 so beware
