Border Patrol DAC tube change

Old thread but,,,

Put Mullard BVA EZ81(Holland made) instead of stock Tungsram EZ80 - big improvement in tone and dynamics. EZ81 can always be used instead of EZ80 - the only difference EZ81 can handle higher plate voltage... Border DAC is stroke of genius.

Bonjour Mmhifi,

Just to know : Could you tell me if the stock ez80 tube was very old? Just wondering if age could be a factor.

PS Before owning the BP, I did not understand why some are saying that tone is more important than details / the last bit of resolution. Now I understand…
 

I had brand new Border DAC - one month only in my system. So stock Tungsram EZ80 was fresh. DAC finished break in and after that I changed the tube. Difference for better was big.

VERY interesting. I will try it. Thanks a lot…
